Today, one of the areas of self-production of metal structures is the use of profile pipes. And if round pipe is used in most cases for laying pipelines, and sometimes for constructing frames and racks, then profile pipe today is a material with a much wider range of applications.
In this article we will look at the most significant aspects of the use of this material, as well as the most common homemade products from a profile pipe.
Pipes of different profiles
Profile pipe
General information about profile pipes
The term “profile pipe” most often refers to a pipe having a cross-section other than round.
The most common profile pipes have the following cross-section:
Most often, the profile pipe is made from carbon or low-alloy steel (grades St3SP, 09G2S or similar). Stainless steel pipes are also available. Aluminum profile pipe can be placed in a separate category - the use of this material differs from the use of steel pipes.
Profile pipe production
Profile pipes are produced by hot or cold deformation of a round pipe blank.
- From the workpiece (the so-called “strip”), a round welded pipe of the required diameter is made by bending and welding (determined by the calculation method).
- The round pipe blank is fed into a forming machine, where it is deformed to the required shape and cross-section.
- To relieve mechanical stress, the pipe (now we can talk about a profile pipe!) is subjected to heat treatment, followed by mandatory inspection of the weld.
Thanks to the formation of stiffening ribs on the pipe, products made from a profile pipe are quite strong - their metal frame can withstand loads many times greater than a frame made from a round pipe of a similar configuration.
Types of country lounge chairs
Depending on the design features, the chaise lounge chair is conventionally divided into several types:
- Monolithic products are chairs in which all components are interconnected during manufacturing and cannot be disassembled. Such sun loungers have good strength, durability and can withstand heavy loads. However, when using such a piece of furniture, certain inconveniences may arise. For example, in such a product it is impossible to change the angle of the backrest, it cannot be folded, due to which moving from place to place will be problematic.
- Monolithic chair with inserts. This type of DIY chaise lounge made of wood has a decorative appeal. The presence of additional fragments made of different materials will reduce strength and reliability, but this will make the chair more aesthetically pleasing and neat.
- Portable chaise longue. The design of such a product provides for a mechanism through which you can quickly and easily change the position and overall configuration of the chair. You can change the angle of the footrest, headrest or backrest. In addition, a folding lounge chair can be transformed into a compact cargo and taken with you when traveling out of town.
- Chair on a metal base. It is somewhat more difficult to make such a chaise lounge with your own hands from a photo, and you often buy a ready-made product. It is distinguished by the presence of an aluminum or steel frame on which a fabric sheet is attached. The advantage of the chair is its light weight, compactness, resistance to dirt and mobility.
Application of profile pipe
Profile pipe in industry
The widespread industrial use of profile pipes has become one of the factors that ensured the popularity of this material.
The most popular in industry are profile pipes 200x200 mm and 150x150 mm - various load-bearing structures are most often erected from such pipes, and the connection of profile pipes is made by welding.
Profile pipes of the specified section with a wall thickness of 6-12 mm provide the structure with strength equal to the strength of reinforced concrete load-bearing trusses.
At the same time, the economic effect of using a profile pipe is quite noticeable!
Canopy frame made of profile pipes
In industry, smaller profile pipes are also used - the use of such pipes is allowed when constructing frames that do not experience significant loads. For example, a 120x120 or 100x100 pipe is acceptable for the construction of warehouse-type structures, change houses, etc.

DIY products from profile pipes
Along with very wide industrial use, today profile pipes are very actively used in private construction.
What can be made from a profile pipe? - Yes, almost anything!
Gazebo on a pipe frame
Profile pipes with a cross-section smaller than that used in industrial construction (for example, 100x50, 80x80 mm, etc.) are used for the construction of small architectural forms. Frames for country houses, domestic and outbuildings, pavilions, kiosks, advertising media, etc. are made from profile pipes.
In addition, fences and gates made from profile pipes have recently become quite popular. Indeed, it is much easier to dig columns of pipes of the appropriate size into the ground than to install concrete pillars or pedestals of appropriate size and strength.
Also, profile pipes can (naturally, with certain precautions) be used as a frame for frame-type residential buildings.
The advantages of using profile pipes for such tasks are obvious:
- With a profile pipe wall thickness of 4-8 mm (the most common parameters), the weight of a linear meter is 12-15 kg. This weight allows you to manipulate frame fragments without the involvement of heavy equipment, which is important if you are building structures from profile pipes on your own.
- Installation of profile pipes, both detachable (using brackets and couplings) and one-piece methods, is quite simple.
- The service life of such a frame is estimated in decades, and with proper protection from moisture, the structure turns out to be almost eternal.
Profile pipes with a cross section of 50x50 and 40x60 mm are widely used for internal frame structures: as frames for workbenches and small machines, for the manufacture of racks, shelves, display cases, trade and exhibition equipment, as well as furniture.
Due to the fact that such furniture made from profile pipes does not experience extremely high mechanical loads, thin-walled pipes (2-4 mm) are used for its manufacture. As a result, the structure itself, as a rule, has little mass.
To produce furniture from profile pipes (most often this is furniture for common areas, such as benches, desks and chairs for educational institutions), a profile pipe with a cross section of 40x25 or 20x20 mm is used. The wall thickness of such a pipe is 1-2 mm, which makes the furniture quite light with high strength values.
A profile pipe made of thin metal (0.8 - 1.5 mm) can be easily processed using a blowtorch.
With a sufficiently low level of heating, you can give such a pipe any shape you need.
That's why profile pipes are so valued by metal craftsmen!
Bed made of profile pipes
Aluminum profile pipes are also widely used for the manufacture of furniture and interior items. Despite the somewhat higher cost, its anti-corrosion properties make aluminum profile pipes very popular.
As you can see, the number of situations in which the use of a profile pipe will be justified is almost innumerable. That's why we strongly recommend that all craftsmen keep this wonderful, inexpensive and practical material in mind. And it’s quite possible that the acquired skill of working with profile pipes will come in handy!

Making a chaise lounge on a frame base using thick fabric
Another popular and simple way to make a chaise longue for a summer house with your own hands is a chaise lounge made of material on a frame. This is a light and comfortable summer cottage option that can be converted from a lounger to a chair and back with one movement of the hand.
You will need the following materials and tools:
- two wooden slats 0.25x0.6 cm of different lengths (120 cm, 110 cm, 620 cm);
- wooden slats 2x2 cm (65 cm - 1 pc., 2 pcs. 60 cm and 50 cm);
- high-quality dense material 2×0.5m;
- drill;
- bolts and nuts of suitable diameter;
- PVA glue;
- “zero” sandpaper;
- round file.
Choose a wear-resistant fabric that is not afraid of open sunlight and moisture. The ideal option would be jeans, canvas or tarpaulin. It is better to choose slats from oak, birch or beech (they have increased hardness and strength).
To make light sun loungers for your garden with your own hands, you need to prepare slats of the required length and sand them.
General information about the profile pipe
The profile pipe can be made with a rectangular, oval, or square cross-section. As a rule, the material for its production is carbon or low-alloy steel. Stainless steel is less commonly used for these purposes.
Since profile pipes have stiffening ribs, they, like the products made from them, are characterized by increased strength. The resistance of such a metal frame to mechanical loads is much higher than that of a frame made from standard round pipes.
Profile pipes are convenient to store and transport. Pipes with a parallelepiped cross-section take up less space when stored and are more secure than pipes in the form of a cylinder.
Necessary tools for working with corrugated pipe
To cut the workpieces, you should use a circular saw - an angle grinder; a hand saw is also suitable. The parts are connected using a welding machine, but those who do not have one or are not skilled enough in handling one can take an electric drill and a set of drills for metal and wood. Also, to work with a profile pipe, you need to prepare a hammer, tape measure, chisel, screwdriver - or an electric screwdriver and a set of attachments, emery cloth.
Those who plan to create a structure with rounded elements are recommended to use a tool such as a profile pipe bender.
Components, tools and basic materials for creating a standard chaise longue with your own hands
Today, using competent drawings, it is relatively easy to make a multifunctional and decorative chaise longue for your site or home. In addition, designs of this type are now presented on the World Wide Web, for the manufacture of which you do not need drawings with your own hands. But you will definitely have to put in some effort, theoretical knowledge and physical labor in order to create a design of this kind that is attractive in appearance and reliable in operation for spending leisure time in a country house under a canopy or for sunbathing (if there is no comfortable swing in the country house).

The necessary tools and components, which are simply impossible to do without in the process of creating a product such as a chaise lounge for the home or a rocking chair for newborns (or for dolls), include a certain list of tools and materials.
This process cannot be done without:
- saws;
- self-tapping screws;
- wood putties;
- roulette;
- sandpaper;
- marker;
- paints of a certain (desired) color range;
- drills (preferably electric);
- square
In addition, it is impossible to make a piece of furniture such as a chaise longue or rocking chair for newborns (dolls) with your own hands without:
- wooden boards, the size of which is 400 cm x 2.5 cm × 8 cm, in the amount of four pieces;
- wooden blocks, measuring 400 cm x 5 cm x 10 cm, three pieces;
- pins, which are intended for fixation, in the amount of two pieces.
Options for the use and application of profile pipes
Now we will look at a number of examples of the use of profile pipes for various structures.
Manufacturing furniture from profile pipes
In the design and production of furniture, the key property of profile pipes is versatility. This material is great for shelves, benches, coffee tables, hangers, open kitchens and desks.
To make furniture from metal elements, you need to follow the following step-by-step instructions: 1) study the drawing of a piece of furniture, cut the profile pipe into parts for blanks;
2) cleaning the cut burrs and drilling the necessary holes; 3) bending of frame structural elements using a tool; 4) welding work to connect structural parts; 5) tie the structure using bolts; 6) preparation and installation of fittings on furniture; 7) installation of wooden and plastic structural elements; painting furniture parts.
Greenhouse frame made of profile pipe
Self-construction of a greenhouse frame from profile pipes requires a certain amount of time, money and effort, but such a structure will last for many years and, as a result, will constantly bring benefits. When planning the construction of a greenhouse, the question of choosing frame material often arises. In this case, a profile pipe is one of the best solutions. The manufacture of a greenhouse, the frame of which is made of corrugated pipe, is described here.
Steel profile pipes for greenhouses are advantageous because different types of coverings, in particular polycarbonate, can be easily attached to them.

Gazebo made of profile pipe
To build a gazebo, a steel pipe with a square or rectangular cross-section is often used. The combination of the strength of the material and the rigidity of the pipes due to their shape ensures uniform distribution of the load on the gazebo, while at the same time the design is lightweight. With this profile, the required dimensions of the gazebo can be easily adjusted, which also has a neat and stylish design.
A gazebo made of profile pipes has many positive characteristics. The main ones are: • lightness of construction due to the absence of a massive base; • stability and long service life; • relatively low cash costs for the material; • fire resistance; • no need to carry out repairs from time to time.
Canopy made of profile pipe
Those who have a private house or just a plot outside the city often think about building a canopy. In addition, canopies made from profile pipes are often found in commercial organizations and public places, such as outdoor cafes, parking lots, recreation and entertainment areas. The main advantage of such canopies is their ease of manufacture - they are quite capable of being made independently. This task does not require special skills or knowledge, you just need to do everything according to the instructions. How to make a carport is described here.

Assembly steps
- you need to drill holes suitable for the selected bolts on each long rail, always retreating 7-10 cm from their edges; all irregularities should be immediately sanded with a needle file until smooth surfaces are formed;
- at the head of the frame (indicated in figure “B”), several holes should be drilled at once for subsequent adjustment of the tilt of the seat back;
- to create a seat, you need to make two more holes at the ends of the long slats; their diameter must match the diameter of the prepared round slats (in this case - 2 cm); To make the slats hold tighter, you should lubricate their ends with PVA glue;
- combine structure “A” and “B” using screws passing through the upper holes, then combine the resulting module with element “B” in the same way;
- stretch the fabric by folding the edges over the crossbars and sewing several seams with strong threads (this procedure can be completed before the final assembly of the product, then you can sew the material using a regular sewing machine).
