Hiring a construction team of 2-3 people costs about 300 rubles per hour. The cost of building materials at the contractor will be 20-30% higher than at a retail outlet, not to mention wholesale warehouses. In general, it is better to keep silent about the conscientiousness of the performance of work. Why not then make a canopy from a metal profile with your own hands and save money and nerves?
Preparatory land work and selection of materials
In order for the construction process to be successful and nothing later had to be redone, it is necessary to immediately take into account all the nuances. This applies both to the selection of the right materials, cleaning the territory, and engineering work to calculate the ultimate load. Consider the sequence of actions.
Step 1 You need to choose a construction site.
If you have several options where you can build a future structure, then it is better to give preference to a place with shallow clay to save on concrete. The angle of the slope of the land should also be taken into account so that your building does not end up in a collection point for water from the entire site - this will provide you with many inconveniences, regardless of what you built it for. It is best to choose a hill or a relatively flat area with the possibility of water drainage.
Step 2 We choose the material.
It is immediately necessary to calculate the cost of the future design. If you use a galvanized metal profile for the roof or powder coated, then a solid cost will come out. If you just buy metal and treat it with anti-corrosion protection, you can save up to 30%. The size of the metal square for the racks must be calculated taking into account the rainfall load per 1 m 2 in your territory + the wind effect coefficient (somewhere around 3.4% for a temperate climate zone). With a size of 4x4 meters and a slope of slopes of no more than 45 0, a metal square of 40x40 millimeters is enough. The greater the distance between the supports, the greater should be their thickness.
Step 3 We clear the area for action.
The floor of the canopy will be concreted, so it is necessary to remove a layer of earth about 10 centimeters from its location, cover it with sand halfway, a little crushed stone and leave about 5 centimeters for a concrete screed. This will be enough for a car weighing 1200-1800 kg. If weighty objects are supposed to be in the canopy, it is better to make a screed 9-12 centimeters. In the course of stripping, we remove all roots from the ground, large stones.
Step 4 We build communications.
Before you build a canopy from corrugated board with your own hands, you need to consider its subsequent operation. The first step is to make ebbs in the ground, calculate their location and other details. In some areas, it is necessary to take into account the availability of electricity, water supply, gasification (depending on the purpose for which this structure is being built).
Now that we already have a "master plan" in hand, we can proceed directly to construction. It is better to check everything at once, since any alteration will cost you a lot or take a long time.
Installing supports and framing
The manufacture of the supporting structure is the most important process, since the durability of the structure directly depends on the correct execution of all actions. An incorrectly assembled frame can simply fall under a solid load in winter or be untidy in appearance. To prevent this from happening, everything must be done gradually, taking into account all possible situations during operation.
Step 1 Installation of columns.
First of all, it is necessary to drill holes in the ground with a diameter of 30 centimeters - they will be intended for the subsequent concreting of metal supports. Next, we insert a support into them, only carefully so as not to pour a lot of earth on the sole of the pit - then the concrete can sag. After you pour 50% of the solution into the pit, you need to take a plumb line, measure everything and adjust the rack left / right. Perform exactly the same operation with the three remaining supports, and then align them in height.
Step 2 We make a binding.
It can be done at the very top - this is a traditional construction method, or you can try extraordinary ways to strengthen the structure. For example, weld the strapping crosswise (the top of one support and the bottom of the other are connected), with a mesh, or even make a double one - at the top and bottom.
Step 3 Crate.
If you have a straight shed roof - there is nothing to fool yourself and come up with "cunning" designs. Just install metal beams every 80 centimeters, a profiled metal sheet will be screwed onto them. With a gable roof it is a little more difficult: we make a straight beam and a ridge, under the ridge there should be a perpendicular reinforcement to the straight beam. One boost is enough. The most difficult option is a double arch. Here it will be easier to buy ready-made bent elements, and then make L-shaped reinforcements every 40-50 centimeters between these arched squares. If the canopy is more than 4 meters wide, a direct additional reinforcement must also be installed.
Do-it-yourself canopies made from corrugated board will cost about 7,000 rubles if you buy metal at the average market price. The installation process will take no more than 1 day, and only 1 worker can do it (you need to be able to use a little welding machine and basic skills in working with a grinding tool).
Preparing the roof
This is the most important process, since the appearance of the entire structure depends on the quality of the assembly. We will mount on a bolted connection - it's much easier. To prevent the roof from leaking, and also to prevent corrosion of the bolts and metal profiled sheet, it is better to use plastic or rubber washers that are worn directly on the hat and can protect the hole from moisture in the winter. Let's take a closer look at the step-by-step instructions for installing the roof.
Private land plots for our citizens are always identified with the hard work of growing their own organic products. However, dachas do not lose popularity, since with the development of the industry in the field of building materials, it has become accessible and easy to ennoble your own dacha and build a corner for relaxation or other pastime on it.
Rolled metal products have become one of the raw materials for the construction of sheds. The welded frame of the canopy is more popular with owners than the wooden one. The process of constructing this object is described below.
Frame canopy from a metal profile - advantages
So, what are the advantages of a metal frame over a wooden one? Let's take a closer look:
- The metal is not subject to deterioration, if corrosion is excluded. The latter is easily eliminated or prevented by applying special means to the structure. The metal frame is not threatened by fire, mold, or rodents.
- A canopy from a metal profile is unknown to shrinkage, in contrast to a similar wooden object. Welding will not bend, the grooves will not dry out, the logs will not crack. Of course, it all depends on the processing, but over time, these problems are inevitable for the tree.
- The lightweight metal profile frame is mobile - it can be moved to any convenient place if the racks are not concreted into the site. In addition, if summer residents are concerned about the durability of the metal frame, then during construction, all elements are fixed not by welding, but by bolts. Thus, for the winter period, the entire structure can be removed in a dry place.
Forms of a metal canopy
We are talking, of course, about the truss system - the rest of the structure is a rack, concreted into the site or installed directly on the ground. So, the features of the forms of the roofs of the canopy:
- Single roof. The easiest option for self-design. It is a plane sloping for a slope of rainwater. The shape allows you to make a canopy of any size, which means that such a place is suitable for any purpose - a barbecue, sleeping places, even a pool. However, this has its own pitfall - large areas will take on an impressive amount of snow, which means that either the structure is dismantled for this period, or a careful calculation and appropriate reinforcements are made.
- Gable roof. Such canopies are rare and can be a roof for extensions - verandas, terraces. Rainfall is facilitated by the steepness of the slopes and the right material for the roof.
- Arch. Canopies prevailing in popularity. They have a feature that other designs lack - the sun's rays are reflected from the roof, and an optimal temperature is created inside.
The following describes how to make a shed canopy yourself, using simple steps for this. You need to decide in advance on the purpose and desired dimensions.
Installation of a shed canopy
Consider a small mobile welded structure, since the advantage of installation in any suitable place is welcomed by all owners of summer cottages. In addition, inexperienced home craftsmen, based on their own product, will receive the necessary training for further creations. So what will be required:
- Welding machine and universal electrodes.
- Level and measuring instruments.
- Profile pipe with a section of 80, 60 and 40 mm. You can also use other rolled metal products - corners or channels.
- Roofing material - cellular polycarbonate. It withstands loads better, unlike monolithic, which is used on vertical surfaces.
- Fasteners, thermal washers, rubber seals.
- Protective minium for metal. You need protective equipment for yourself and you can start.
Calculation of a metal frame for a canopy
Professionals use in their work data from the area about the amount of precipitation that falls during the season, soil conditions and other figures. This is a prerequisite for structures exceeding a length of 10 m and a width of more than 5.
The creation of a small structure must also be subject to certain parameters. For example, how to calculate a shed metal canopy yourself:
- The canopy length of 6 m should have 8 supports. A profile pipe from 80 mm and above with a cross section and a wall thickness of 3 mm or more will completely cope with the task of stability.
- One side of the canopy should be higher than the other according to the chosen angle of inclination and roofing material - 20-25⁰ is enough for polycarbonate.
- Each pair of supports should receive reinforcement in the form of trusses. They are made of equal-shelf corners or a profile pipe with a cross section of 60 mm.
- The crate is welded in increments of 1 m from a pipe with a cross section of 40 mm. Such a design can withstand up to 400 kg of wet snow, if it is decided not to transfer or dismantle the canopy for the winter period.
Site preparation
A do-it-yourself mobile single-sided canopy made of a metal profile is notable for the fact that it does not require special preparation. It is only important to level the ground by removing the turf for this and tamping the ground.
Subsequently, under a canopy, you can make a lawn, a wooden platform or lay out paving slabs. Under the racks, pits should be dug in advance so that the structure does not begin to sag.
Frame assembly
The whole structure is assembled "upside down" for convenience. Only the roof is laid on top. So:
- First, a frame is welded from a profile pipe or corners.
- Racks are evenly fixed.
- The supports receive reinforcements in the form of trusses - corners welded to them at an angle.
Now, the slag is beaten off, the welds are cleaned and the structure is turned over for installation in place. It is important to wrap the ends of the posts with several layers of roofing material in order to reduce the effect of constantly wet soil on the metal.
Assembly of the truss system and roofing
When the canopy is already stable, they begin to weld the crate. According to the drawing, metal pipes or corners are fixed at a distance of at least 1 m. It is immediately necessary to drill holes in the crate and frame of the entire rafter system to fix the polycarbonate.
It is impossible to cut sheets of plastic in advance - there is a risk of incorrect measurements and, as a result, the coating will have to be redone. It is better to do this on top of the finished frame. The sheets are overlapped without fixing, the attachment points are marked and cut out at the bottom.
Fixing is not complete without the use of thermal washers, as an additional sealing of the metal frame from moisture. Double protection of the structure should also be in case a single-sided wooden canopy is conceived with your own hands - then rubber o-rings are glued to the logs, at the attachment points.
When the material is ready for the final coating, the metal frame should be brought into a decorative form in advance, not forgetting about protection. Surikami - with protective compounds against corrosion, the finished canopy is painted even before the roofing - so, there is a chance not to miss a single centimeter of metal. Next, polycarbonate is laid using a connecting profile, and at the end of the work, protective end caps are installed so that moisture in the form of evaporation does not penetrate into the plastic cells.

How to make a canopy from a profile pipe with your own hands
Canopy structures made of shaped pipes can be found in many places: in the yards of country houses, on the territory of summer cafes, in parking lots and other public places. Their main advantage is that you can do all this with your own hands. To do this, you do not need to have special skills and knowledge, just follow the detailed instructions.
Scope of application and installation of a canopy from a profile pipe
The metal profile today has become one of the most popular and sought-after materials for the manufacture of canopies of various types and types with a polycarbonate coating, since its main advantage is a long service life. If such a building is properly looked after, then it can stand for more than a dozen years. Such canopies can be used in a variety of places:
- in car parks;
- in country private houses to create large covered areas of the territory;
- in various public places.
The scope of canopies from a metal profile is quite extensive, since they are universal structures that have a large number of different modifications.
The most popular today is the arched type of product. It is much more difficult to make it than a single or gable, but it looks very impressive. Such a canopy is built separately from the house or adjacent to its side.
When choosing the type of roof, it is necessary to take into account the fact that the snow does not linger on it, but falls freely to the ground, without creating a large load on the roof.
In addition, there are canopies of a dome, arc, pyramidal shape, as well as single-slope and dual-slope.
In addition to polycarbonate, slate or metal corrugated board can be used for roofing. Therefore, we can say that the complexity of erecting a canopy from a professional pipe directly depends on the choice of frame design and materials chosen for the roofing.
Preparatory work: drawing development
First you need to accurately determine the location of the canopy, as this is very important for choosing the material for the future structure and roofing. It is best to place them on a flat area or hill, as it will be easier to make the necessary drainage there. If you decide to build a structure in a lowland, then the collected water will "force" you to make additional storm sewers, which will entail unforeseen costs.
It is also important to make a preliminary drawing of a canopy from a metal profile. In addition to the location of the racks, it is necessary to take into account the cross section of the profile pipes. If the length of the structure does not exceed 6 m, and the width is 4 m, then for the installation of supports, you can take a pipe with a cross section of 60x60 mm. For the construction of a large structure, a pipe with a cross section of 80x80 mm is taken.
List of required tools
To make a metal canopy, you will need a certain set of tools:
- building level;
- bayonet shovel;
- apparatus for welding;
- roulette;
- rule (level);
- drill;
- Bulgarian;
- perforator;
- bolts and washers;
- profile metal pipes;
- roofing screws with special gaskets;
- building corner;
- polycarbonate, corrugated board or slate;
- cement, sand, medium gravel;
- flange.
Calculation of the required number of profile pipes
For the construction of a small shed canopy, it is necessary to make accurate calculations and draw up a preliminary drawing:
- A canopy 6 m long should have 8 supporting metal racks. To do this, you can use a metal profile with a section of 80x80 mm. The wall thickness of the pipe should be more than 3 mm for greater structural stability.
Do-it-yourself step-by-step instructions for making a canopy structure from a professional pipe
The sequence of work depends on the type.
Shed canopy
This design is the simplest. For its manufacture you need:
- Install supports and fill wells. The distance between the posts should be from 1 to 1.5 m. If slate, corrugated board or natural tiles are used for the roof, then this value is 1.2 m.
- Outline the location of the support pillars, pull the construction rope between them in a straight line. For each rack, dig holes at least 60 cm deep and 20 cm in diameter. Reinforce the pipes with special strips (heels) that are welded to the bottom of each of the pipes. They will then be completely filled with concrete, and will hold the entire structure in a vertical position.
arched structure
The construction of an arched canopy is carried out in almost the same way as a shed, but they are more aesthetic and functional.
It is quite difficult to build an arched canopy on your own, since for this you need to have special manual or electrical equipment so that you can easily bend the metal profile. At home, it is almost impossible to perform such actions.
double awnings
A gable canopy is mounted similarly to a single-sided canopy, however, there are two triangles in the structure, which are mirrored relative to each other. The roof of such a canopy is formed by two inclined planes at a certain angle.
Due to the presence of a ridge knot, this design has a more complex structure system, but it can cover a much larger area of \u200b\u200bthe site.
Multi-slope canopies
Such structures are used to cover large areas such as car parks, exhibition pavilions, etc. At their core, they are a series of sequentially arranged gable structures. Here, in addition to the ridge knot, which is located at the upper points, it will be necessary to create a drainage system.
How to weld a professional pipe
In the process of carrying out any welding work, safety precautions must be observed. Also, after completion of all work, each weld must be cleaned of slag so that there are no joints. This can be done with an ordinary grinder with a special metal hedgehog nozzle.
To connect metal structures from a profile with a wall thickness of more than 3 mm, it is best to use gas welding, since an electrical analogue may simply not “pull” such an amount of work.
How to bend a metal pipe
For this, a special pipe bender is used. With it, you can easily bend various types of metal profiles. But if there is no such tool at hand, then a grinder and welding will help to cope with the task.
It is very important when bending various pipes to prevent the appearance of cracks and large kinks, which should not be in the structure of the canopy. Also, they should not be flattened. In the process of working with a manual pipe bender, considerable physical effort must be applied, so it cannot be used to bend a profile with a cross section of more than 40 mm.
External finishing of the structure
After the structure of the canopy frame is fully welded and cleaned of scale, it is necessary to degrease all metal elements before painting them. To do this, you can use a common solvent, acetone or gasoline, which must be allowed to dry. After that, you can start the priming process.
Light gray primer suitable for any type of paint. Dark is used for bright materials. White is usually used when painting a metal profile with pastel colors.
The primer can protect the metal from premature corrosion, and thereby significantly extend its service life, as well as reduce paint consumption.
Do-it-yourself canopy construction from a profile pipe - drawings, instructions with photos and videos
Scope of canopies. Manufacturing preparation process. How to make a structure from a profile pipe with your own hands: step by step instructions. Video.
We could also consider gable structures, but the purpose of this particular article is to make an extremely practical, simple and cheap canopy with a metal frame, so we chose a single-slope structure. Make it 2 times faster, since there is no need for bent trusses, joining the roofing material in the center and materials will go 30% less. Consider the entire instruction step by step and start with the preparatory work.
STEP 1: choose a place for a shed canopy. You can build wherever there is space, but it is better to choose a small hill in the yard and a place with shallow clay so that water after rain does not accumulate under a canopy, and you can spend a minimum of money on installing concrete under the supports. Fans of Feng Shui are not welcome here, since the main thing here is practicality.
STEP 2: choice of materials. We have already chosen it. Our supports will be made of a metal square 40x40 mm, we selected it taking into account the load of the structure and the possible wind load of 4%, we also did not forget the precipitation for the harsh climatic zone. The supports are designed for a metal canopy with a slope of 15-20% and dimensions of 4x4 meters. The roof can be made of polycarbonate, but we still preferred metal corrugated board, as it is inexpensive and easy to work with. 
STEP 3: clearing the area. We will use a concrete floor for the car, so the area must be planned and about 10 cm of earth removed for adding slag and installing a screed at least 5 cm thick. This is a lot, quite enough for a heavy SUV (within reason, up to 2500 kg). If you want to buy a hummer or a tractor in the future, then your screed depth will be at least 12 centimeters. 
STEP 4: calculate communications. Yes, you heard right, there will be more communications around the canopy. What for? It's simple. Firstly, water will not wash it away, it will not flow under a canopy, and secondly, it just looks cool and is inexpensive. These will be ebbs in the ground and drainage systems. In addition, it is necessary to supply electricity to the shed just in case of a fire (suddenly there will be nowhere to fry a barbecue or you need to warm up the car) and make wire conclusions from under the screed or along the supports in the future. 
Metal carports can be of different sizes, you can make it just for a car, or you can create a parking lot for 3-4 places (suddenly the mother-in-law will come to visit or former classmates), it is better to think it over in advance, since the expansion will be problematic. At the very least, you need to pour the foundation and supports immediately to the size of the canopy you have chosen and start manufacturing after the calculations. Look like that's it. Now we have prepared the site, morally gathered and accepted for courage - you can go to build.
We install metal poles for a canopy and crate
Making the frame is the hardest part, because installing the roof and decorating is already a breeze and even a child can handle it. But the frame must be carefully done, do not be lazy to use the level and more often check the correctness of the work. If you install the supports or the screed unevenly, then it will be possible to fix it, of course, but it will take a lot of time and effort, because this is almost completely redoing everything. Consider how to concoct a metal canopy with your own hands according to GOST in detailed instructions.
STEP 1: install the supports. There are about dozens of different methods for installing supports, but we will not bother our heads with lower strapping, we just make a 40-50 cm deepening in the ground with a drill or a shovel, put a metal profile in the center and fill it with concrete - the support is ready. Here it is important to install the supports exactly vertically, measure everything with a level so that they are in the same plane. We make a concrete solution 1: 3. 
STEP 2: top strapping. But at the top it is necessary to tie the supports, since their height will be 270 centimeters above the ground and 240 cm, respectively, on the other side, where the slope will be (we chose just such a height), they may deviate slightly. Therefore, at the top along the perimeter it is necessary to weld a metal profiled pipe, the length of which will be equal to the length of one side (we took the dimensions of the canopy 4x4 meters as a template). 
STEP 3: crate. Since metal sheds with a shed roof do not require bent elements and joints in the middle, making the crate is as easy as shelling pears. It is necessary to weld a metal pipe every 60 centimeters between the sides of the canopy with a height of 270 and 240 cm to form a slope. We will get about 20% slope, even a little less - this is quite enough for the metal frame of the canopy to successfully cope with any amount of precipitation. 
Now it remains only to screw the roofing material. The frame will cost only 3,500 rubles, you can still save money by installing jumpers every 80 centimeters, instead of 60 cm as we did, but it’s better to have a margin of safety, you can make the construction easier only if the carport is located in a cozy place in the yard and not exposed to strong winds.
We select and fix the roof on a metal carport
As we said earlier, it is possible to lighten the structure and attach polycarbonate to the roof, but this will not be very rational from the point of view of efficiency. It is best to make a shed metal canopy from corrugated board. In addition, it does not need to be bent, leveled, put tricky washers and it’s not scary to pull a little. Installing it is easier than a steamed turnip, consider the step-by-step instructions:
STEP 1: drill holes. It is necessary to lift the metal sheet and make holes in it at the level of the metal beam that connects the sides of the canopy. This can be done simply: put the sheet on the beam, mark the bottom with a marker where you need to make holes, remove and drill them. Holes every 35 centimeters. 
STEP 2: drill out the metal carport. Holes can be made both in advance in the marked places, and when the sheet is already applied to the frame and a jumper is drilled through the hole on the corrugated board. It is necessary to use special screws with sealing caps so that the screwing points do not rust. You can use plastic washers to work, it's convenient and cheap. 
STEP 3: treatment with protective materials. It is better to use deep impregnations for metal and varnishes so that our work will stand for many years. When using varnish, metal canopies for summer cottages last at least 2 times longer, since even high acidity of precipitation does not cause corrosive processes. 
We looked at how to make a metal canopy without the help of a specialized team, but we also suggest watching a video on how to properly screw the corrugated board to the metal frame in order to avoid mistakes:

The choice of a place for the construction of a canopy is a very important stage of work.
It is also important to make a preliminary drawing of a canopy from a metal profile. In addition to the location of the racks, it is necessary to take into account the cross section of the profile pipes. If the length of the structure does not exceed 6 m, and the width is 4 m, then for the installation of supports, you can take a pipe with a cross section of 60x60 mm. For the construction of a large structure, a pipe with a cross section of 80x80 mm is taken.
A preliminary drawing of a canopy from a profile pipe is necessary for calculating the material
List of required tools
To make a metal canopy, you will need a certain set of tools:
- building level;
- bayonet shovel;
- apparatus for welding;
- roulette;
- rule (level);
- drill;
- Bulgarian;
- perforator;
- bolts and washers;
- profile metal pipes;
- roofing screws with special gaskets;
- building corner;
- polycarbonate, corrugated board or slate;
- cement, sand, medium gravel;
- flange.
Calculation of the required number of profile pipes
For the construction of a small shed canopy, it is necessary to make accurate calculations and draw up a preliminary drawing:
- A canopy 6 m long should have 8 supporting metal racks. To do this, you can use a metal profile with a section of 80x80 mm. The wall thickness of the pipe should be more than 3 mm for greater structural stability.
Supports for a canopy from a profile pipe must be strong
- One side of the structure must be higher than the second, depending on the chosen roofing material. So, for example, for polycarbonate, an angle of inclination from 20 to 25 degrees will suffice.
- For each pair of racks, reinforcement structures called trusses must be provided. They are made of equal-shelf corners or a profile with a section of 60x60 mm.
The main method of joining metal parts is welding
- The crate is welded in increments of 1 m from a metal profile pipe with a section of 40x40 mm. Such a canopy can withstand about 400 kg of snow, provided that the structure is permanently installed.
- For the installation of racks, you will need 8 profile pipes.
- For the roof sheathing you will need 12 profiles. In some cases, homeowners save money, install only 6 instead of 8 racks. You can also reduce the number of pipes for the crate, but experts do not recommend doing this, as this will lead to a loss of rigidity, and in the future to the destruction of the entire structure.
The number of racks should be such that there is no doubt about the rigidity of the structure.
- The basis of a shed canopy is a triangle of shaped pipes, which has one angle of 90 degrees. Its larger leg should be equal to the distance that corresponds to the length from the end edge of the post to the wall of the building or to the outside of the opposite post if the canopy is built far from other houses.
A shed canopy is the simplest design
Do-it-yourself step-by-step instructions for making a canopy structure from a professional pipe
The sequence of work depends on the type.
Shed canopy
This design is the simplest. For its manufacture you need:
- Install supports and fill wells. The distance between the posts should be from 1 to 1.5 m. If slate, corrugated board or natural tiles are used for the roof, then this value is 1.2 m.
- Outline the location of the support pillars, pull the construction rope between them in a straight line. For each rack, dig holes at least 60 cm deep and 20 cm in diameter. Reinforce the pipes with special strips (heels) that are welded to the bottom of each of the pipes. They will then be completely filled with concrete, and will hold the entire structure in a vertical position.
A shed canopy from a profile pipe can be placed anywhere in the backyard
- Lay and compact a small layer of sand at the bottom of each hole. Then install the support strictly vertically in level, and pour concrete (mix sand, cement and gravel in a ratio of 3:1:3). After that, raise and lower the support several times so that the mixture penetrates into the internal cavity of the profile.
- Check the vertical position of all supports with a building level, leave them until the concrete dries completely. It usually takes 3-7 days, depending on weather conditions. If you are building a canopy on an existing concrete surface, then metal racks can simply be screwed to the base, having previously welded special square plates to the bottom of the pipes.
- Form the upper part of the shed canopy. To do this, it is necessary to weld two pipes, which are located along the legs of the structure. Then measure the hypotenuse of the truss, cut off the profile of the desired length, weld it to a certain place. If a pipe with a rectangular section is used, then it is necessary to mount it in such a way that it is turned upwards with its larger side, which will facilitate the fastening of the cladding.
- Reinforce the finished hinged structure. To do this, in a metal triangle between the largest leg and its hypotenuse, weld pieces of a profile pipe.
- Calculate and install all frame elements. To do this, weld metal strips to the smaller leg of each triangular element. In this case, the side of the frame should divide the slats into two identical parts.
- In this frame element, make four identical holes in order to attach the canopy to the wall of the house. To do this, you will need another person who will help install the base, and mark the position of the holes for the anchor bolts. But since shed structures with corrugated board or slate are very heavy, this fastener may not be enough, so you have to install additional racks that are screwed to the wall. A shed canopy, in which the roof is made of polycarbonate sheets, is much lighter and therefore additional fasteners near the wall are not needed.
A canopy made of polycarbonate from a profile pipe does not require additional fasteners
- Polycarbonate is fixed to the roof of the canopy without removing the protective film. Using a drill, you need to drill holes in the sheets. In this case, 4 cm will have to retreat from the edge. Special thermal washers with o-rings and plugs are used. In the process of attaching polycarbonate to the roof of the canopy, you need to put a thermal washer on the drilled hole, then screw it in with a self-tapping screw, close it with a special cap with a plug. The fastener must enter strictly perpendicular to the surface of the roofing sheet. It is necessary to twist tightly, but at the same time it is impossible to overtighten, so as not to spoil the surface of the sheet.
Attach polycarbonate sheets to the frame with special plastic washers
- All polycarbonate sheets on the roof of the canopy should be joined using a special split profile. Screw the bottom of it onto the crate before laying the roof. Fasten the cover with a toothed lock, in which the "legs" are located on two parts of the profile.
It is necessary to join polycarbonate sheets to each other using a special profile
- Then close all side cuts of polycarbonate sheets with a special perforated tape and an end profile. Thus, you can protect the air channels of the roof from dirt and moisture penetration.
The ends of polycarbonate sheets must be protected

arched structure
The construction of an arched canopy is carried out in almost the same way as a shed, but they are more aesthetic and functional.
It is quite difficult to build an arched canopy on your own, since for this you need to have special manual or electrical equipment so that you can easily bend the metal profile. At home, it is almost impossible to perform such actions.
An arched canopy from a profile pipe cannot be made without special equipment
double awnings
A gable canopy is mounted similarly to a single-sided canopy, however, there are two triangles in the structure, which are mirrored relative to each other. The roof of such a canopy is formed by two inclined planes at a certain angle.
Due to the presence of a ridge knot, this design has a more complex structure system, but it can cover a much larger area of \u200b\u200bthe site.

Multi-slope canopies
Such structures are used to cover large areas such as car parks, exhibition pavilions, etc. At their core, they are a series of sequentially arranged gable structures. Here, in addition to the ridge knot, which is located at the upper points, it will be necessary to create a drainage system.

Photo gallery: finished designs from a profile pipe
An arched canopy in the form of a visor is ideal for the porch of a house. A gable canopy will perfectly hide your car. An arched canopy for a gazebo can be made of multi-colored polycarbonate.
You can build a metal canopy from a profile pipe yourself quickly enough, without much effort, if you have the appropriate materials, drawings and the necessary tools. The simplest structure that can be built on the territory of a country house is a shed canopy. The main thing at the same time is to follow all the rules of installation, to follow exactly the developed scheme of the project.
Metal sheds are reliable, functional outbuildings, durable, practical, but visually light, harmoniously fit into the landscape of the site, do not clutter up the natural landscape. In the article, we will analyze the advantages and disadvantages of metal structures, what is better to build from, we will offer examples of simple projects, we will tell you how to correctly calculate the dimensions of the building, as well as its individual elements.
We will give detailed, step-by-step instructions on how to make a shed canopy from a metal profile with your own hands, for example, the drawings were chosen with average sizes, if necessary, they can be adjusted to individual conditions.
General characteristics of metal canopies
Canopies made of metal, a photo diagram of a standard design is given below, you can make it yourself, even if you are far from construction. The design of the building is simple - these are vertical pillars, a truss truss is attached to them, then a crate is arranged, then a roof.

Application area
Metal awnings are widely popular in private individual as well as commercial construction. These are covered parking lots, stops - a shelter for people waiting for public transport, structures above the entrance to the building, according to the regulatory regulations, their presence is mandatory in houses above 2 floors, visors above the gate, galleries leading from the gate to the house, outbuildings - shelters for firewood, other utensils, gazebos - from mini structures to combined buildings, sometimes two-story.

Constructive
Metal canopies can be divided into three types:
- Mini designs - visors, mobile gazebos, mono-product - barbecue with a roof.
- Independent detached metal buildings.
- Combined - extensions to the garage, house, bath, etc., more often it is a veranda, a terrace - a place to relax, or a shed for household purposes.

The project of a canopy of metal structures is made based on the functionality of the building, these can be:
- open buildings, consisting of supports and a roof;
- closed buildings, where the sides are sewn up with sheet material, panels, wood, gratings, glazed, closed with thick curtains, awnings, fabrics with special moisture-resistant impregnation, canvas, soft glazing.

Tip: For glazing a metal canopy, it is recommended to use sliding aluminum systems, they do not block the view, the sections can be moved to open the building as much as possible. Such glazing is a reliable protection against precipitation, dust, gusts of wind, in a slight frost it will maintain a favorable microclimate inside, which will make rest comfortable at any time of the year.
Large metal structure combined with brickwork
Open metal canopies, due to the low weight of the structure, are often arranged on the roof of a garage, summer kitchen, gazebos. Such a solution is a great opportunity to organize a comfortable recreation area with a gorgeous view, if there is no space for an independent building on the site.
materials
Metal canopies are divided according to the materials of manufacture:
| Material | supports, | truss system | Auxiliary elements, crate | Fastening |
| The thickness of the walls and the section of the profile depends on the size of the structure | ||||
| round pipe | 50-100 mm in diameter | Ø25-30 mm, often the truss is made of wood | Ø18-25 mm | Welding |
| Profile rolled | Profile rib 50-150 mm | 25*25, 40*30, 25*50, 40*40 mm with a wall of 2 mm for small, medium buildings, 3 mm for large buildings, or a 60*40*2 mm profile is used | 40*20mm | Welding on a metal scarf or bolted connection |
| Prefabricated structures made of aluminum profile | Finished products are assembled as a constructor: on washers or end method | |||
| Canopies made of stainless steel | Only professionals can make a quality product with their own hands; a special type of welding is required. Canopies made of stainless steel do not require finishing or additional protection. | |||
| Forged Products | The most luxurious, sophisticated type of canopies that will decorate the house and the site. There are 2 options for implementing the idea: order a finished building or do it yourself. The first solution is simpler, but comparing the cost, there are less financial costs, if you weld a frame from a metal profile, decorate it with forged parts, serial stamping, which you can buy on the market, will cost less at a price. | |||
It is more practical, more economical - to build a canopy from a profile pipe with your own hands. Over time, it can be closed with curtains, glazed, overlaid with brick, stone, decorated with forging, wooden grating.

The technical side of the issue - projects, diagrams, drawings, calculations
Analyzing any drawing of a canopy from a profile pipe, the structure can be represented in two parts: a metal frame and a roof. The base is vertical pillars made of a round pipe or a square profile, along the upper heads of which there is a strapping with rolled metal or the lower belt of the truss. This gives rigidity to the metal structure, helps to maintain the geometry even under significant loads.
supports
Pillars are recommended to be placed at a distance of 1.5-2 m from each other. If the building is adjacent to the house, garage, sauna, etc., then it is advisable to place support columns near the main building that will hold the canopy. In the absence of such an opportunity, in order to tie the canopy to the house from the metal profile, with your own hands you should attach a transverse beam to the load-bearing wall, which will serve as a support for the farm. Long anchors are used in the work. The solution will help distribute the load evenly across the entire load-bearing wall.
Farms
The main load from precipitation and gusts of wind falls on the truss system of the canopy, so it is important to make the correct calculation of the trusses, to determine the thickness of the profile for its manufacture. Canopies from a metal profile, photo examples below, are arranged under a single, gable or arched roof.
Which canopies can be made from a profile pipe with your own hands, photo examples of different types of roofs
Farms are:
- Triangular, polygonal, parallel, broken - determined by the contour of the belt.
- Inside the belt there can be lattices - triangular, rhombic, slanted and semi-slanted.
- According to the method of support - cantilever, beam, arched, beam-cantilever.
Typical truss arches for metal canopies
In order to correctly calculate a truss from a profile pipe for a canopy, it is necessary to take into account snow and wind loads, the angle of the roof, and the size of the structure. Experts will help you avoid mistakes in rather complex engineering calculations or you should use an online calculator.
For the manufacture of small or medium metal canopies, in private it is better to use ready-made drawings and projects, to make universal trusses that are suitable for all types of structures.
Standard shed trusses
The optimal roof slope is 15-25o, suitable for all types of roofing material: polycarbonate, corrugated board, soft roofing, metal tiles, etc.
Requirements for materials and fastening
In order for a frame for a canopy made of a profile pipe to meet quality standards, a number of conditions must be met:
- It is unacceptable to use a profile with cracks for the manufacture of units that carry elements of the canopy.
- The end face of the supporting ribs must have a roughness of Ra £12.5 µm, which is regulated by GOST 2789-73.
- For trusses of the lower belt, steel without internal layers is used, coarse slag inclusions are strictly prohibited.
- According to GOST in section 14771-76, joints should be made by mechanical welding, using carbon dioxide or a mixture of carbon and argon.
- Guided by paragraphs 2246-70 and 26271-84 of GOST, PP-AN-8 wire is required for welding.
- GOST in part 7798-70 states: rafters are attached to vertical supports and rafter parts with class 5.8 bolts.

How to make a metal canopy with your own hands - step by step instructions
We will make a canopy from a metal profile with our own hands, we took typical drawings, adapted them to the size of the site, the dimensions of the building are 4 * 3 m, the roof is made of polycarbonate 8 mm thick.
The standard scheme, according to which we will build a canopy from a metal profile with our own hands, a photo of a typical design with an arched roof
Foundation
We enclose the site with pegs, pull the rope, mark the installation site for the pillars, check the geometry, the diagonals should be equal. We remove the upper soft layer of soil, dig holes for supports, 700 mm deep.
Attention: If the terrain is swampy, uneven terrain or the ground on the site is quicksand, then it is better to equip the pile foundation.
We fill the bottom with crushed stone and sandstone, layers of 100 ml, we ram the pillow. The site can be lined with paving slabs or poured with concrete. For concreting the site, a reinforcing frame is made of corrugated rods, a cell of 100 * 100, 200 * 200 mm, is laid on a pillow so that the reinforcement does not touch the bottom by 50 mm, pebbles or ready-made coasters should be placed. A crate is installed around the perimeter, a 100 mm thick slab is poured with concrete at once, without interruptions. The fittings must be immersed in the solution by 50 mm from all sides.
How to concrete a metal pole
We pour concrete at the bottom of the pits, a layer of 100 mm, insert pillars from a profile pipe, check the verticals, fill the solution to ground level. If necessary, we set the selections until the concrete has completely solidified in order to maintain the geometry of the frame for the canopy.
After a week, when the solution gains strength, we file the pillars to size. We weld the harness along the upper heads, this will fasten the building and give it rigidity.
How to weld a truss for a canopy
The farm is best made on the ground, then raised to the frame. To bend the profile, you can use a special machine or make a rigid template with your own hands, according to which the details of the farm will bend. In large stores, a service is provided for bending a metal profile along standard radii. Farms should be installed every meter, there are 5 of them in our construction. We need 10 curved parts, as well as a 30 * 30 * 2 mm profile for internal stiffeners.
How to bolt a truss to a metal frame
We cut the farm elements to size, cook the main nodes of the truss system. When all the parts are ready, we lift them with a crane onto the frame, then we attach them to the strapping with bolts or by welding onto a steel scarf. Next, we weld the crate from a profile of 40 * 25 * 2 mm, a distance of 750 mm.
Treatment
After assembly, we clean the frame with a stiff brush, remove scale, remove signs of corrosion, then go through with sandpaper to finally get rid of the lesions, as well as increase the adhesion of the surfaces. Before painting, to degrease the frame, it should be washed with a rag soaked in a solvent, when it has completely evaporated, it can be primed.
Useful advice: A light gray primer is suitable for any color of paint, dark mixtures are relevant for bright colors of paint, for pastel colors it is better to use a white primer.
The primer will protect the canopy from corrosion, significantly reduce paint consumption. If the coloring composition does not have good hiding power, then the primer layer will provide a reliable protective layer and a uniform color. Under hammer compositions, one layer is sufficient; for coating with conventional paints, it is better to apply primer 2 times. Metal canopies are painted with brushes, rollers, spraying from an airbrush is most beneficial, which will significantly speed up the process, reduce paint consumption by one and a half to two times, and provide an even, holistic, reliable, aesthetic coating.

How to fix polycarbonate to the metal frame of the canopy
For metal canopies, it is better to use cellular polycarbonate. Cut with a grinder with a disc for metal. Sand the edges with a fine abrasive to remove burrs. You can fix polycarbonate on thermal washers or using a special profile.
In the first case, holes are made 2 mm larger than the diameter of the fastening leg. A rubber seal is put on the washer, which prevents dust and moisture from getting inside, the part is inserted into the hole until a characteristic click. Point fastening allows the material to maneuver a little, which protects the polycarbonate from deformation, cracking during the operation of the material during cooling or heating.
Thermal washer mount
The profile connection is more hermetic, it is justified when it is necessary to join the panels. The edges sit on thermal washers. Which type of profile to choose depends on the type of roof, so it is selected individually.
Detailed diagram-instruction on how to properly bend and fasten polycarbonate
Subsequently, the sides of the canopy can be sewn up with blank panels, glazed, hang curtains or plant grapes, climbing roses, climbing plants, when they grow, you get a beautiful, lively gallery.
Be sure to see how to make a canopy with your own hands from metal, the video tells in detail how to join the main components of the structure, cook the farm, and strengthen the frame. The video tells in detail what errors had to be encountered in practice, as well as how to eliminate them.
The design of the canopy, which is simple at first glance, requires preliminary calculations, and before erecting the frame, it is recommended to draw at least elementary drawings. It is worth doing this out of material savings - in order to accurately calculate the need and use expensive materials as completely as possible. In addition, the correct calculation will ensure the reliability of the structure and its ability to withstand gusts of wind.
What is included in the canopy?
Any canopy is a structure with a roof and no side walls. Thus, in any canopy, several mandatory elements will be installed:
- racks or supports;
- overlap runs;
- elements of vertical and horizontal links.
And if it is easy to calculate the need for materials for racks and for floor runs and is quite capable of doing it yourself, then a design engineer or any other specialist familiar with the basics of drawing can correctly calculate and draw a drawing of a farm. If there are none, or you decide to make your own canopy from “a” to “z”, then a few tips will help you figure this out. We will talk about how to make a canopy from a profile pipe - this is the most commonly used material for canopies. Although the drawings are the same for any material, including wooden structures.
Briefly about supports
Most often, steel pipes with a square or rectangular section are used for the manufacture of supports. The round section of an ordinary pipe will also work, however, difficulties may arise with it at the junctions of structural elements.
As for the parameters of the pipe, that is, its thickness and wall width, then there is a whole methodology for determining taking into account loads. However, in a small structure, these calculations can be neglected, since with a relatively small vertical load on the canopy roof, even a thin-walled pipe will not be deformed. In general, use either a thin-walled pipe with a wide cross section, or a thick-walled one, but with a small cross section. From the point of view of costs, it is more economical to use thin-walled with a large sectional perimeter.
As a standard, a do-it-yourself canopy from a profile pipe is made from a pipe with a size of 50-100 mm. The pipes can be thinner if the racks are placed more often. If the roof rests on only four pillars, then it is better to make them from a pipe of a larger diameter or section.
Supports are poured with concrete or installed with anchors. In the first case, particularly careful derivation of the vertical level is required. In the second, with the help of anchors, it is still possible to subsequently correct some skew of the support.
Farm calculation and drawing
Since the canopy is exposed to the wind, you need to very securely fasten the frame of the cross-beams with the uprights. The transverse beams are fixed as rigidly as possible on the uprights; for this, the metal elements should be securely welded or bolted at two points on each of the supports.
It is more reliable to install a pair of crossbars, which are interconnected by cruciform ties.
Next, proceed to the calculation of the truss - a structure that firmly and tightly connects the transverse beams to the supports and the crate, creating a monolithic frame system.
The farm is designed depending on the type of roof of the canopy.
The simplest roof is a pitched roof. More difficult are gable and multi-pitched roofs. The calculation of the arched roof is made in a special way. But whatever the design, it is important to know that with an increase in the height of the farm, its bearing capacity will increase, so in winter the snow will not linger on such a canopy roof.
With strong stiffening ribs, you will increase the strength of the entire structure.
For stiffeners, of which there will be several, you need to choose a strong pipe. Its size is determined by the size of the canopy structure itself:
- metal pipe size 2x20x40 mm is used in the construction of small sheds, less than 4.5 m;
- pipe size 2x40x40 mm is used in construction up to 5.5 m;
- over 5.5 m will require a pipe with a size 2x30x60 mm.
The distance between the pipes cannot be more than 1.7 m, so this must be taken into account when planning the farm step.
The larger the overlapped side, the more racks and, accordingly, the more expensive the canopy comes out, the more difficult the work will be. It is optimal to make a span of three meters, it will provide sufficient area and at the same time will be minimal in terms of costs.
Single slope canopy
This canopy is the easiest to make. For its installation, only simple runs from a pipe with a square or rectangular section are required.
The beams should be calculated taking into account the loads on them, the climatic features of the region and the length and pitch of the runs, the weight of the proposed roof. It is better to entrust the calculations to a specialist. For self-calculation, we can recommend small beams of 3-4 meters and a profile for them of 80-100 mm.
The upper and lower belts are connected by a central post, the upper beam is reinforced with a strut. Other types of canopies, including arched ones, should be mounted according to separate calculations. In this case, the frame is built on the basis of the above schemes.
How to cook a canopy and collect it
If you do not know this craft at all, then it is better to entrust welding to a specialist. But if you have a welding machine and skill, then you will be able to make, among other things, welding with a tubular section. First, splicing is carried out along the edges. Then continue to the center. Spot baiting, level checking, straightening with a sledgehammer, welding of all elements are the stages of welding. As a rule, the side parts and rafters are assembled alternately and separately, and then they are also placed in turn on the supports - the side ones and then on them and the rafters. With a lift, the frame can be completely assembled directly on the ground and lifted into place already assembled.
The finished frame is placed on supports, this will require help, since one pair of hands is not enough. Next, the same spot welding is carried out, accuracy is checked using a level, and finally, constant welding is carried out. When the frame is assembled, the joints should be cleaned to remove scale, and then the metal frame is treated with an anti-corrosion coating. Often the metal profile already has such a coating. If it is not processed, the processing must be carried out independently.
Important: All metal frame elements should be carefully checked for anti-corrosion treatment. If the surface of the coating was damaged during installation. Needs to be re-processed. Only in this case the canopy will serve for a long time.
Manufacturing of crates
A wooden crate is placed on the farms, on which the roofing is installed. The easiest and most reliable way is to lay a simple metal profile flooring. It is reliable, quite durable, and is relatively inexpensive. The use of polycarbonate sheets for the manufacture of canopy roofs is also common today. In addition, no one has canceled slate, and you can also use polymer sheets.
In order for the crate made of wood to last longer, wooden structures should be treated with antiseptic preparations. Polycarbonate roofing is laid directly on the girders of the farm.
A canopy is a simple design, which, nevertheless, is very important for any suburban area, cottage, etc., since it allows you to protect from rain, a summer terrace, a parking lot, etc. One of the most popular is a hinged structure made of metal profile, since this material is inexpensive, durable and practical. Today we will talk about how to make the simplest (single-sided) canopy from a metal profile with your own hands (drawings, photos and video instructions are attached).
From the metal profile it is used mainly in cases where the most reliable protection of any area from precipitation is required. The metal profile is very popular due to a number of undoubted advantages:
- Environmental friendliness. The metal profile fully complies with all regulatory documents and requirements for roofing materials.
- Fire resistance. The material undoubtedly wins against the background of plastic and tiles, having a fairly high level of fire resistance: even near an open source of fire, the material will not ignite.
- Thermal stability. The metal profile tolerates sub-zero temperatures quite normally (not the slightest freezing was noticed at a consistently low sub-zero temperature). In addition, the material responds well to sudden temperature changes (during temperature fluctuations, neither chips nor cracks are noted).
- The high quality of the material allows you not to worry about the repair of the roof for 5-10 years. The metal profile is strong enough, but it is very easy to install.
Roofing materials - Aesthetic appearance. A rich color palette and a variety of shapes of profile sheets allow us to talk about the possibility of choosing a unique product, based on the features of the exterior, etc.
- Affordable price. The material is affordable for most segments of the population, so it is beneficial to use it for small home sheds.
During the construction of canopies, special attention is paid to the choice of a certain form of construction, since its practicality and convenience will largely depend on this. So, shed canopies can be considered the simplest form, presented in the form of an inclined plane located at a certain angle.
This design has its own distinctive features, among which one can note the natural drainage system and ensuring maximum protection of the territory.
Advice. The sloping surface does not allow precipitation to accumulate in large quantities, so shed canopies are especially relevant for use in regions with high rainfall.
Do-it-yourself construction
The manufacture of a canopy from a metal profile is a rather laborious process, therefore it requires careful study of the details and well-executed calculations. About all this further.
Carrying out calculations and preparing materials
So, if you decide to make a shed canopy with your own hands, first of all, pay special attention to several issues:
Shed canopy - drawing - Tilt angle. This indicator should be calculated in such a way that there is no excessive steepness, otherwise it is likely that moisture will get under the canopy, and in large quantities.
- drainage system. The drainage system must be carefully planned in order to avoid the appearance of a powerful water flow that can wash away the soil under the structure.
- Slope direction. When choosing a suitable place for mounting a hinged structure, you should carefully study the statistical information regarding the direction of air masses.
- Additional reinforcement. This parameter must be taken into account without fail in those regions where frequent strong gusts of wind are observed.
Advice. If we are talking about building a canopy with our own hands, it is best to give preference to a shed design, since all the rest are quite difficult to manufacture and install, so only those who have professional skills can do it.
Using a tape measure, measure all the main parameters of the site for the installation of the future structure. Given the figures obtained, calculate the amount of materials that will be required to create a canopy.
Assembly and installation of the structure
First of all, you should carefully clean the area under the canopy from various debris, branches, foliage, etc. Then level it. Now you can proceed directly to the preparatory work. Let's start with the foundation (in this case, the supports). Make markings for the supports, keeping a distance of about 1 m between them.
Shed canopy made of metal profile In places where markings were left, make recesses for the supports and carefully compact the soil at the bottom of each hole. After that, fill each hole with a partially drainage layer consisting of a mixture of sand and gravel. Place the supports in the prepared recesses, carefully level them and fill with concrete.
After the concrete dries, it is possible to weld longitudinal beams and girders to the supports, which will be used as supports for metal profile sheets. A welding machine is best suited for this work, but if one is not available, you can replace it with self-tapping screws and a screwdriver (however, it is difficult to call such a design reliable).
The last stage is the laying of metal profile sheets. You should start from the lowest level. Lay the sheet and fix it on the beams with special screws. The next sheet should be laid in the same way, but slightly overlapping the previous one. We move in vertical rows.
Here, in principle, are all the subtleties that should be considered when creating a shed canopy from a metal profile. Good luck!
