Drawings for the construction of sheds. Metal poles for a canopy Design options for canopies made of metal pipes

Architectural structures made from profile pipes can be found everywhere; they are installed in summer cottages, near large stores and industrial sites, next to government and commercial institutions. You can make a canopy yourself if you have basic skills in working with a welding machine.

Compared to brick, concrete and wooden canopies, pipe structures have a number of undeniable advantages.

In addition, such structures have a relatively low cost. Light weight allows for significant savings on excavation and foundation work. Such positive characteristics of canopies have become the reason for their popularity among numerous consumers.

Stages of construction work

Any construction work requires a careful and very balanced approach and planning of your actions several steps ahead. In addition, you need to have special tools and practical experience working with them.

Important. Any welded canopy is a source of increased danger to others. The work should only be performed by a professional welder who guarantees the quality of all seams.

Table. Stages of manufacturing a structure

Stage name	Brief description and practical tips
	At this stage, you need to decide on the location of the canopy and its functional purpose. The canopy can stand alone, next to the house or other outbuildings. It can be used to protect swimming pools or sports fields from precipitation, used as a shelter for a car or various industrial products. Only after the general requirements for the canopy have become clear can we proceed to the next stage.
	It is necessary to take the dimensions of the future structure, select the optimal type of roof from numerous options, and select roofing materials. At the same time, you should decide on the type and size of the foundation and all linear dimensions of the structure. It is strongly recommended to draw a sketch of the general view of the canopy, separately all its elements, and indicate their dimensions. Make details of the responsible loaded nodes.
	Carefully calculate the amount of materials, taking into account unforeseen expenses. If the project is created independently, then due to the lack of experience in performing such work, some elements will necessarily need to be adjusted during the construction of the structure. It is important to remember that any stop in construction due to a lack of materials always causes an increase in the total estimated cost. At the same time, the serviceability of tools and equipment should be checked. Buy electrodes of the appropriate diameter, cutting discs, hardware, etc.
	A very important stage. It is necessary to weld trusses and spans, prepare vertical supports. Depending on the project, braces and other elements are provided to increase the mechanical strength of the structure. In this case, it is necessary to ensure that the dimensions of each element are strictly observed; the actual distribution of loads and their compliance with the calculated ones largely depends on this.
	In most cases, it is more rational to perform such work with assistants; this not only speeds up the assembly process, but also makes it safer and of higher quality. The order of connecting individual elements into a single structure depends on the engineering features of the project.
	Sheds can be covered with polystyrene slabs (monolithic or cellular), profiled metal sheets, flexible bitumen shingles or other roofing materials. Taking into account their physical parameters, the dimensions and type of sheathing, slope angles or bending radii of arched rafter systems are selected. If desired, decorative forged elements are installed on the structure.

Step-by-step instructions for making a canopy

As an example, we take a 6 m wide canopy without intermediate supports. Such a large distance between the supports requires the manufacture of strong supporting beams on which the canopy will lie.

Step 1. Calculate the required amount of materials for construction. For the manufacture of trusses, you can use a pipe with a cross-section of 40×20 mm, for beams 40×25 mm. The wall thickness in both cases is two millimeters.

Practical advice. Always reserve approximately 5–10% of the estimated quantity. We have already mentioned that an independent project cannot provide for the exact number of pipes.

Step 2. Start making beams. The length of the element is 6 m, vertical intermediate posts for such a beam must be placed every 60 cm. The height of the structure is 30 cm. To increase resistance to bending loads, two differently directed jibs are welded between the vertical supports. You can cut pipes with an ordinary manual grinder, but if you have a large volume of such work, then it is recommended to make a basic machine. Check all beams against the template; their dimensions must be exactly the same.

Step 3. Make load-bearing trusses. They can be made according to the same engineering scheme, only with reduced dimensions. The height of the structure is approximately 25 cm, the pitch of the vertical jumpers is 75 cm. The forces on each of them are not as great as on the beams, which makes it possible to reduce the size of the units.

Step 4. Thoroughly clean the structures from scale, metal stains and technical oil. Prime and paint surfaces.

Step 5. Reinstall the beams and trusses and weld all structures. Work very carefully. We have already mentioned that canopies are considered high-risk structures; all components must exactly meet the calculated load-bearing capacities.

Step 6. Everything is normal - start installing the drainage system on the canopy. Gutter hooks must be metal and can be welded or screwed to the beams. We recommend the first fixation method - it’s much easier and faster.

Important. Do not forget to make a slope - per linear meter the difference in height between the fixation elements must be at least five millimeters. For our 6 m long canopy, the total slope will be three centimeters.

Now you can cover the canopy with cellular polycarbonate slabs

If you live in a private house, sooner or later you will need to install a canopy near the house, which will serve as reliable protection for your car, as well as a cozy place to relax. A country canopy in the yard can be used to create a comfortable stay, because it provides good protection from the scorching rays of the sun and precipitation. In addition, depending on the type of structure, it can also be used for decorative purposes, for climbing flower gardening and planting vineyards.

Today, there are a huge number of different models of country and yard canopies, which differ not only in appearance and characteristics, but also in material, as well as purpose. One of the simplest and most popular types of country house canopies today is a structure made from a profile pipe, which you can easily make with your own hands. As a rule, this type of metal canopy is highly durable, durable and stable. Visually, such buildings are quite light; they will not burden the appearance of the yard.

Canopy made of profile pipe

The most important feature of this type of design is the low cost of materials and ease of installation. You can easily install canopies made from profile pipes yourself, provided you have the necessary tools and patience.

Other advantages of structures made from profile pipes include:

• reliability of the material;
• flexibility - you can create both straight and arched structures from profile pipes;
• ease of assembly due to the correct shape of the material;
• minimum tools for installation;
• long service life;
• when created from a frame profile, it will be lightweight;
• quick connection of material using bolts or a soldering iron;
• frames made of similar material can be either collapsible or stationary;
• affordable price of material.

Country canopies made of profile pipes can be divided into two types depending on the type of structure: separate and stationary. Collapsible structures, as a rule, are created on the basis of an installation with a frame made of profile pipes, as well as using plastic or fabric with a waterproof coating.

This design is very convenient, and its installation will not take you much time. A collapsible garden canopy has the following benefits:

• fast assembly process;
• ease of installation;
• convenience and mobility;
• Possibility of use only in certain seasons;
• low price.

The stationary type building is a prefabricated structure, the main material for creating the frame of which is metal pipes. As a rule, such a design also has a more complex installation process, but if you have minimal construction skills and a set of necessary tools, you can do the installation yourself.

Before you begin installing the structure, you need to decide on its type. When choosing the type and size of a country or yard canopy, especially if it is made by hand, it is best to give preference to rectilinear structures, the installation process of which is simple. The rectangular design with two ribs can also provide high stability and strength to the canopy.

Straight canopy diagram

In addition, the choice of material is also an important aspect in this process. It is best to give preference to the highest quality and durable materials so that there are no problems with the finished structure in the future. For this purpose, pipes made of high-carbon steel, which are protected from the effects of corrosion and rust, are better suited. When it comes to choosing the size of the structure and the thickness of the walls, this will depend entirely on the type of shed you have.

High carbon steel pipes

Before starting construction work, it is necessary to carry out preparatory work, which includes drawing up a project and design drawing, as well as calculating the dimensions and quantity of materials. All calculations are made strictly according to the developed drawing of the canopy. The project must indicate the dimensions of the structure, the relationship between the length of the building and the angle of the roof. In the work drawing it is also necessary to indicate the outlines of the support belts. In this case, the height of the building must be calculated based on weight, type, ability to move, type of floor and other features. If you have any difficulties at the stage of developing a project or design drawing, it is best to contact professionals who can draw up a competent project for you.

Work on installing the canopy must begin with marking and installing the frame. After you have made marks on the place where the canopy will be installed, you can proceed to installing the structure's supports.

Installing a canopy support

For light garden or yard structures, it is best to install supports in increments of up to 2 m. First, you need to dig holes 60 cm deep, compact them, cover them with a layer of gravel and proceed to creating a column from concrete mortar. Each column is installed using a plumb line.

Columns made of concrete mortar

It is worth noting that this type of work is best done not alone. In order to install the columns exactly at the level, you will need more than one pair of hands. The place under the suspension must be strengthened; for this purpose, they can be covered with tiles or simply create a concrete screed.

Concrete screed

Next, you need to proceed to the installation of a frame made of reinforcement, and also fill it with concrete to a depth of at least 50 mm. Such a base can withstand loads of no more than 3 kg. The next step will be to create a frame around the perimeter of the canopy, which will serve as a fastening for the roof truss.

Now you can move on to working with the pipes themselves. First, you need to weld cylinders with through holes to one end of the profile pipe, which will serve for fastening to the base of the structure. Holes must be drilled at the ends of the support to secure the frame and stand. You can then begin assembling the pipes using bolts.

Ready canopy

If you want to make the job faster and easier, you can use special metal plates instead of cylinders. However, in such a case, the reliability and strength of the structure is significantly reduced.

Today, this type of canopy, the arched one, is very popular. A design of this type is distinguished not only by high strength and reliability, but also by a very attractive appearance, due to which its scope of use is expanding. Arched canopies made of profile pipes are a fairly simple structure in type and construction, the installation of which can be done with your own hands. You can often find arched buildings in private houses and dachas, which perform both decorative and protective functions.

Arched canopy

Before you decide to build an arched structure at home, you need to worry about choosing high-quality material, preparing the necessary set of tools, and developing a construction project. At this stage, it is mandatory to create a project or detailed drawing, which will indicate the calculation of parameters and placement of the structure, as well as the amount of materials needed.

Arched canopy project

This stage of construction is very important, therefore, if it is difficult for you to develop a competent project yourself, you can use ready-made projects of canopies and profile pipes on the Internet. On the Internet you can find a wide variety of developed drawings of finished structures made from profile pipes. You can easily use a detailed drawing to build a canopy with your own hands, this will greatly simplify the work.

The process of installing an arched canopy made of profile pipes has the following features:

It is worth considering that materials for creating an arched canopy will have to be ordered or purchased in a specialized store. The store will also help you correctly calculate the radius of materials based on the desired width of the canopy.

Today, a canopy made from a profile pipe can be found in literally every yard. This can be either a small canopy over the porch or a spacious covered parking lot for several cars.

The popularity of this building material is understandable - the structures are beautiful, strong, and the work on their construction takes very little time. In this article we will cover the main issues regarding the design of a canopy made from a profile pipe.

Canopy made from corrugated pipe: calculation, drawings, construction and types of fastenings

Large canopies require special attention when making calculations - for a car, a swimming pool, a recreation area, etc. Small canopies for lean-to canopies can be made with your own hands without taking into account SNiP.

How to calculate a canopy, drawings

The calculation of a polycarbonate canopy made from a profile pipe begins with creating a sketch. It reflects the desired type of construction and finishing, as well as approximate dimensions. We determine the exact parameters only after going to the site of the future location of the structure - we take measurements of the construction site and the wall of the house, if the frame of the canopy from a profile pipe is attached. The sketch can be made either manually or using a special program.

We make a canopy from a square pipe with our own hands: a sketch made in a computer program

Initial data for calculations: the house is 9 x 6 m, there is a free area (9 x 7 m) in front of its free side.

• The canopy can be made the width of the entire wall of the house - 9 m, let the overhang be a meter shorter than the site - 6 m. We get a structure 6 x 9 m.
• The optimal height of the low edge is 2.4 m, the high edge is raised to 3.5 or 3.6 m.
• Based on the difference in height of the slope, we calculate its angle of inclination - it turns out to be 12 - 13 degrees.
• We look at the wind and snow maps of our area and calculate the probable loads from them.
• Based on the obtained figures, we select materials and proceed to drawing up a drawing of a canopy from a profile pipe.

Separate drawings must be made for the roof trusses. Several of their options are shown in the following figure.

Making trusses from profile pipes for a canopy: diagrams of different types of structures

Note: SNiP allows you to calculate a truss from a profile pipe for a canopy with a slope of 6 degrees. However, it is better to start from at least 8 degrees. This is due to the fact that a small slope in winter will create the problem of snow accumulation on the roof surface.

Drawing with dimensions

The process of making a canopy from a profile pipe

Making a small wall canopy from pipes is not at all difficult. We begin design calculations and selection of suitable materials. This process is described in the previous and next paragraphs. Next, according to the drawing, we mark the working site, or rather the location of the foundation pits on it.

• We dig holes to the required depth.
• Place a layer of crushed stone at the bottom.
• We install embedded parts vertically into the holes.
• Fill the hole with cement-sand-gravel mortar.

We weld squares of steel onto the lower ends of the racks, the size exactly matching the areas of the embedded parts. The bolt holes must also match. After the foundation pillars have hardened, we screw the posts to the mortgages.

Now we move on to assembling the roof frame. We mark the corrugated pipe and cut it into pieces of the required length. We first weld or bolt together the side trusses, then the front lintels, and at the very end we mount the elements of the bracing grids, if they are needed. In the process, we check the building level; you can also use magnetic corners. We lift the finished frame onto racks and fix it with hardware/weld it.

For your information: Before installing the roofing material, the corrugated pipe canopy must be painted or treated with an anti-corrosion compound. This is due to the fact that during the assembly process of the structure, the factory metal protection is damaged at the points where the fasteners enter.

Types of fastening elements to each other

Very often, canopies are assembled using through bolts or self-tapping screws. This method is good because you do not need welding in the process - not everyone knows welding techniques. All you need is the hardware itself and a drill with a metal drill. The diameter of the selected bolts/screws directly depends on the cross-section of the corrugated pipe - the salesperson at the building materials store will advise you on this matter.

We assemble canopies from a profile pipe with our own hands: photo of fastening with through bolts

Welding is no less popular for assembling canopies from corrugated pipe than bolts or self-tapping screws. A welding machine, electric or gas, is required for operation. The latter involves the use of a certain number of consumables. Welding provides a very strong fastening that does not violate the integrity of the body of the elements. For example, the same bolts require drilling holes, which weakens the entire structure.

Note: The disadvantage of such installation is the complexity of the process. Not everyone knows welding techniques at a level sufficient to assemble structures under heavy loads. Therefore, if you are not confident in yourself or do not have the opportunity to hire a specialist, it is better to give preference to bolts/screws.

How to make canopies from a profile pipe with your own hands: the photo shows the welds

Small canopies made of profiles with a cross-section of up to 25 mm are assembled using special clamps, or, in other words, a crab system. They are T-shaped - to connect three ends and X-shaped, to connect four ends. The clamps are tightened with bolts (6x20 or 6x35) with nuts - hardware is usually not included in the kit and must be purchased separately. The disadvantage of the crab system is that the elements are connected only at an angle of 90 degrees. Welding is not appropriate here, since the corrugated pipe of the specified section has a small wall thickness.

How you can fasten a canopy from a profile pipe with your own hands: crab systems

For your information: The corrugated pipe has anti-corrosion treatment only on the outside; the inside metal surface remains susceptible to rusting. Therefore, all sections of the structural elements of the canopies must be closed with plugs.

Choosing a professional pipe for a canopy: size and cross-section

When choosing professional pipes for large canopies, you must use data from SNiP:

• 01.07-85 - regulates the combination of snow loads and the weight of structural elements of the building.
• P-23-81 – work with steel products.

Based on the data from these provisions and your own needs, you will need to decide on the following: choose the angle of the roof, the type of corrugated pipe for the racks and the type of trusses. For example, let’s take a wall-mounted canopy 4.7x9 m, the front edge of which will rest on the posts, the rear edge will be rigidly attached to the wall of the house. Location, for example, Krasnodar region. The optimal roof inclination angle for canopies of this type is 8 degrees. The snow load for a 4.7x9 m roof for this area will be 84 kg/m2.

The approximate weight of one rack (2.2 m) is 150 kg, the vertical load on it will be 1.1 tons. A round corrugated pipe with a cross-section of 43 mm and with walls of 3 mm, popular in construction, will not work here, the minimum values ​​are 50 mm and 4 mm . The square pipe can be 45 mm with a wall of 4 mm.

Table of correspondence between wall thickness and section

The simplest and most convenient version of trusses is two parallel belts with a diagonal lattice. With a truss height of 40 cm, a square corrugated pipe with a cross-section of 35 mm and a wall of 4 mm is better suited for chords, and 25 mm and 3 mm for diagonal gratings. The connection system must go along racks and trusses.

Example of a roof truss

A canopy made of pipes and polycarbonate is becoming an increasingly popular architectural form on a personal plot. No wonder, because this building can perform many functions, ranging from an open garage for a car, a wood warehouse, an indoor playground and ending with a recreation area with a barbecue and soft chairs.

The key advantage is the ability to make such a design with your own hands. This article will provide recommendations on the choice of material, examples of calculations of supports and trusses, and how to weld a canopy from a profile pipe.

Calculation of the optimal canopy shape

The length of the rafter depends on the angle of inclination of the truss. For different angles, it is optimal to use different roofing materials:

• 22-30 is the optimal angle of inclination for buildings in areas with significant snow loads. The design of a canopy made from a profile pipe with such an angle provides a predominantly triangular shape. It is optimal for straight and corrugated asbestos sheets, various types of metal profiles and ethernite roofing.
• 15-22 - are also gable with metal types of roofing. This angle of inclination is typical for regions with increased wind loads. The maximum span of a triangular truss with this angle is 20 m.
• 6-15 – predominantly single-pitched trapezoidal trusses covered with polycarbonate and corrugated sheets.

Calculation of a canopy made of polycarbonate from a profile pipe is carried out in accordance with SNiP P-23-81 “Steel Structures” and SNiP 2.01.07-85 “Loads and Impacts”.

The technological requirements for the farm and the calculation sequence are as follows. In accordance with the technical specifications, the required span is determined. Using the presented diagram, we substitute the dimensions of the span and determine the height of the structure. The angle of inclination of the truss and the optimal shape of the canopy roof are set. The contours of the upper and lower chords of the truss, the general outlines and type of roofing are determined accordingly.

Important! The maximum distance at which trusses are placed when making a canopy from a profile pipe is 1.75 m.

Diagram of the dependence of the length of the rafters on the angle of the roof when calculating a truss from a profile pipe for a canopy

Profile selection

As a material for assembling a truss, you can use channels, tees, angles and other profiled products made from steel grade St3SP or 09G2S (in accordance with GOST). However, all these materials have a significant drawback compared to profiled pipes - they are much heavier and thicker with comparable strength characteristics.

The dimensions of the frame elements for a canopy made from a profile pipe depend on the dimensions of the building. In accordance with GOST 23119-78 and GOST 23118-99, the following materials are used to create a canopy from a square pipe with your own hands:

• For compact buildings with a span of up to 4.5 m – 40x20x2 mm;
• Medium-sized structures with a span of up to 5.5 m are made of corrugated pipe 40x40x2mm;
• Structures of significant size with spans of more than 5.5 m are assembled from profile pipes of various sections 40x40x3 mm or 60x30x2mm.
• The size of the canopy stand made from corrugated pipe is 80 80 by 3 mm.

Drawings, dimensions and main connections

Before you begin assembling a canopy from a profile pipe with your own hands, you need to draw a detailed plan of the entire structure indicating the exact dimensions of all elements. This will help calculate the exact amount of materials of each type and calculate the cost of construction.

In addition, it is advisable to make an additional drawing of the most complex structures. In this case, it is a single-pitched truss and the fastening points of its main elements.

Scheme for making a truss from a profile pipe for a canopy with the main fastening units

One of the main advantages of a profile pipe is the possibility of a faceless connection. This is manifested in the simplicity of the design and low cost of the truss with a length of rafter spans of up to 30 m. In this case, the roofing material can rest directly on the upper chord of the truss, provided it is sufficiently rigid.

The advantages of a bevelless welded connection are:

• Significant reduction in truss weight, compared to riveted or bolted structures, up to 20% and 25%, respectively.
• Reducing labor costs and manufacturing costs, both for single products and for small-scale production.
• Low cost of welding and the ability to automate the process by using devices with a device for continuous feeding of welded wire.
• Equal strength of the weld and the products being connected.

Disadvantages include:

• The need to have quite expensive equipment;
• Welding experience required.

Bolted connections in the production of products from profile pipes are quite common. They are usually used in collapsible canopies made of profile pipes or in products produced for mass consumption.

The main advantages of such connections are:

• Easy to assemble;
• No additional equipment required;
• Possibility of complete dismantling of the structure.

Flaws:

• The weight of the structure increases;
• Additional fasteners required;
• The strength and reliability of bolted connections is somewhat lower than welded ones.

Summing up

The article examined the design and methods of making the simplest single-pitch canopy from a profile pipe with your own hands, however, profiled pipe is a rather “flexible” material from which complex and aesthetically attractive structures can be made.

A complex design for creating a canopy from a corrugated pipe with your own hands, photo of a lean-to, dome structure

Outbuildings such as sheds can be found in many suburban areas. Under the roof arch of the open structure, it is convenient to arrange a recreation area, a place to store a car and garden tools. Therefore, the question of how to weld a canopy from a profile pipe with a minimum investment is relevant for many owners who are ready to independently build the structure they need on their farm.

What to consider before starting construction

A beautifully designed canopy is an excellent design solution that complements the architectural ensemble of the site

Constructing a lean-to canopy from a profile pipe is a feasible task that can be completed by any owner who has basic skills in repair and construction work.

To calculate the future canopy from a profile pipe, there is no need to have special knowledge. It is enough just to take into account a number of points.

1. Determine the functions that the structure will perform and the angle of inclination of the roof of the structure.
2. Calculate the optimal height of the support pillars, length and width of the canopy.
3. Calculate the dimensions of the panel structures and determine the distance between the main components of the future canopy.

The number of support posts is determined by their load-bearing capacity with the expectation that the metal will be subject to load not only from its own weight. In winter, large snowdrifts that have considerable weight can accumulate on the roof surface.

The canopy can be a structure adjacent to the house or free-standing.

When designing an independently standing structure, the number of supports should be taken twice as large as when constructing a canopy combined with a house.

You can make a drawing of a canopy from a profile pipe yourself, or use ready-made solutions by looking at them on thematic construction forums.

Important! To create a reliable structure that will serve you well for more than one season, the support pillars should be rested on a concrete base.

It is worth considering in advance how to connect the elements. If the canopy is adjacent to the wall of the house, then provide for the installation of embedded parts or supporting shelves.

Technology for installing a canopy from a profile pipe

Selection of materials

The first step is to decide what the structure will be built from.

The material for constructing the frame will be a profile pipe.

It has high axial compressive and bending strength, and is also characterized by minimal weight with maximum manufacturability. In the manufacture of simple, lightweight structures, cold-rolled or electric-welded pipes can be used.

For the manufacture of supports, it is better to choose square pipes. They will ensure maximum pairing of elements placed at right angles. In addition, on the straight surface of the posts it will be easier to make any type of connection, be it bolted, threaded or welded.

For vertical racks, it is more advisable to choose profiles with wide shelves, the size of which varies between 50-100 mm, and thin walls.

When planning to slope the roof, you should take this into account in the lengths of the support posts.

When choosing pipes for purlins, it is worth considering that, unlike support posts, they will experience force in the transverse direction. Three- to four-meter rectangular pipes with a height of 80-100 mm can withstand such a load. To connect the main structural elements, the easiest way is to use a small-width steel angle.

The most commonly used coverings are:

• galvanized sheet metal;
• metal tiles;
• corrugated sheeting;
• polycarbonate

The choice of roof design is limited only by the preferences and financial capabilities of the owner.

Tools for making a canopy will require:

• measuring equipment (ruler, marker, tape measure);
• construction knife and hacksaw for metal;
• shovel or drill;
• welding machine;
• hammer and screwdrivers;
• surface level;
• screwdriver and electric drill;
• set of wrenches;
• soldering device for fixing fittings to pipes.

Preparing the base

Installation of a lean-to canopy from a profile pipe involves excavation and concrete work.

The site for the construction of the future canopy is cleaned and leveled. Along the perimeter of the installation of the structure, holes are prepared for deepening the supports. The size of the holes must be at least 100x50 cm. Support pillars must be installed rigidly in the foundation. To do this, they need to be walled up in the concrete body, building a strong columnar foundation.

Installation of supports

All elements of the future canopy must be cut according to precisely verified drawings that correspond to the calculations.

The cut racks are installed one by one in dug holes. When installing poles, it is important to control their verticality using a level or plumb line.

After making sure that the installation is correct, concrete is poured.

To give strength to the future support, pour a small part of the solution into the hole and lift the pipe so that part of the mixture gets into its cavity. The racks filled with the solution are left until completely hardened.

Frame making

The complexity of making a roof directly depends on the pitch of the support posts and the length of the side to be covered. The most optimal option is when the structure has a three-meter span, thanks to which it is possible to obtain a maximum covered area with minimal material costs.

The easiest way is to build a pitched roof using simple purlins from a rectangular pipe.

To do this, crosswise mounted tie elements are secured to the installed racks by welding, fixing them at two points on each plane of the rack. Horizontal guides are mounted to the upper ends of the supporting pillars, which will hold the sheathing.

Video: how to weld profile pipes

Profile pipes are laid parallel, maintaining a pitch of 300-400 mm. Fastening is carried out by welding or self-tapping screws.

Design of the structure

The finished structure remains to be covered with roofing material. The installation method depends on the type of roofing material. When working with corrugated sheets, the sheets are attached to the transverse beams, placing them overlapping and secured with self-tapping screws mounted on rubber washers.

To impart rigidity to the structure, the longitudinal wall of the constructed frame can be formed at the base with blocks or bricks.

All metal structures need protection against corrosion. To do this, after cleaning the surface and welds, they are coated with special paints for metal.
