How to bend a profile pipe without a pipe bender at home. How to bend a profile pipe with your own hands: technologies and devices for bending How to bend pipes

Drywall has already become an integral part modern renovation. From this finishing material you can create various complex curly elements for walls and ceilings, as well as assemble beautiful partitions. And everywhere you will need to bend profiles, which are an integral part of the frame needed to install drywall sheets.

Therefore, the question “how to bend the profile?” remains very relevant. If everything is done correctly, then in the end you can get exactly what you wanted.

The structures that are made of drywall today often contain a variety of curvilinear and curly elements. Especially often they are used in the installation of suspended ceilings. Here you can find the following options:

  • circles and ovals;
  • squares and rectangles;
  • various geometric shapes;
  • waves, steps, flowers, sun and much more.

complex ceiling

In addition, bending a metal profile will be needed in other situations:

  • arch installation. Here the profile should be bent into an arc;
  • creation of a single composition of walls and ceiling when the figured elements of the ceiling flow onto the wall;
  • installation of niches with curved elements;
  • creating a curly partition. It can be decorative, contain complex curves and curls, or be straight.

Drywall arch

In any of the above situations, in order for the installation of drywall to proceed according to a given pattern, it is necessary to bend the profile. If you do the whole process correctly, then the subsequent installation of drywall sheets will be quick and easy, and the end result will please the eye for many years.
As you can see, in almost any repair using drywall, bending profiles at different angles is a necessity.
bending metal elements the frame for drywall sheets is carried out according to the scheme. Therefore, in order to correctly fold the profile, you need to read the corresponding instructions. We present it below.

What is required for bending?

Working with metal profiles for drywall requires a certain set of tools. In order to bend metal elements and make cuts on them, as well as to carry out their further installation, you will need the following tools:

  • screwdriver;
  • screwdriver;
  • pencil, tape measure and building level;
  • scissors for working with metal.

To the list necessary materials in this situation will include:

  • metal profiles;
  • fasteners. Here you will need self-tapping screws.

Don't forget to protect yourself while doing the work. So, you will need protective gloves that will prevent cuts and scratches on your hands. In addition, you may need protective goggles.
With such a set of materials and tools at hand, as well as taking all precautions, the procedure for giving the profiles the necessary shape will take you 20 minutes at most.

Getting Started

At the moment, there are two main types of profiles: guides and rack.

Note! You can only bend the profile guides, since the rack ones are used to support the main weight of the drywall structure.

In addition, when creating an arched opening, you can use a special arched profile.
Regardless of which frame element is used, bending methods can be applied to all of them. It is necessary to bend the profiles before they are installed.

The bend is given to the element due to cuts at a right angle. The angle here should be 90 degrees, i.e. direct.
There are two options for the execution of cuts, which depend on which part the further installation of the frame element will be carried out:

Side notch

  • an incision at a right angle of 90 degrees is made on both side parts of the profile. The base of the element remains intact, which allows you to keep the stiffeners intact. This method is great for making arches, semicircular elements or a circle;

Note! When using this method, you need to remember that the smaller the bending radius is needed, the more often you need to make cuts at an angle of 90 degrees.

  • an incision is made on the basis of the frame element. It is also necessary to cut one of the side parts of the profile. This method is used to make ovals or wavy elements.

Often curly elements are made on the ceiling. Therefore, it is necessary to start their formation only after the frame of the first level has been assembled and sheathed with plasterboard sheets.
The procedure for forming a bend is as follows:

Notch on side and base

  • we apply markings on the first level of the frame or wall surface (in the manufacture of decorative shelves). This stage is mandatory, since without markup it is impossible to make complex curly elements;
  • we take the guide profile and shorten it to the length we need;
  • to shorten the element, you need to use scissors for metal;
  • further, depending on the method of cutting, we make an incision at a right angle of 90 degrees. The cuts must go strictly parallel to each other, otherwise the element will not be able to bend. The step for incisions can vary, depending on the needs. But often it is 5-8 cm;
  • we make incisions where you need to make a curl or along the entire length of the profile;
  • we apply the incised profile to the marking line;
  • after that we fix the finished element, bending it in the course of action. Must be fastened with self-tapping screws. Here you should be extremely careful not to cut yourself on the sharp edges of the metal product;
  • you need to fix the element sequentially, carefully giving it the desired shape.

Curved element fastening

Note! Self-tapping screws are installed whenever a bend needs to be made. This will give the final design more fluidity.

When attaching a frame with curved elements, be sure to check each profile with a building level. It is necessary that all frame elements are in the same plane. Only in this way will you be able to make a flat surface of the ceiling or walls.
To give greater rigidity and strength to the curly element, we mount rack profiles inside it.
After that, you can carry out the installation of drywall. The main thing here is that the pieces from a single sheet are cut to exactly the required size. If they do not fit slightly, they can be cut to the desired length with a drywall cutter.
Following this instruction, you can correctly bend any metal profile and give it absolutely any shape.

Things to remember

So that the procedure for giving elements metal frame the required form has passed correctly, you need to follow some rules and recommendations, because only in such a situation you will be satisfied with the end result:

Sheet fastening

  • There are several types of profiles that differ in purpose and size. You need to choose a frame element based on what kind of structure you plan to design;
  • strictly follow the steps given in the instructions;
  • to create curly elements, you can use two types of guides - "UW" and "UD". These elements do not have profiled sides. Therefore, it will be possible to make a couple of cuts on their sides without problems;
  • in rare cases, the use of "CD" profiles is allowed. But only if they do not carry a load and are part of a small curly element. Cutting their sides at a right angle will be a little more difficult;
  • the curvilinear frame structure must correspond to the parameters of the element that were applied to the drawing;
  • installation of drywall on a curved profile should be carried out using self-tapping screws;
  • the greater the bend in the profile, the smaller the step will need to be done when installing drywall. So you will achieve maximum attachment of sheets to the frame, without the formation of cracks;
  • use the right tools, especially for notching profiles. So you will avoid damage to your hands and quickly cope with the entire amount of work.

By adhering to these rules, you can easily create unique drywall curly elements at home, giving your home a new, original look.
As you can see, there is nothing complicated in bending the metal frame elements. The shaping process drywall sheets much more difficult than for profiles. You just need to follow exactly all the points of the above instructions and the result will be great!

A tubular frame made of pipe rolling with a square, rectangular or round section attracts many gardeners with its strength and long service life. Due to the high strength of this material, the greenhouse frame can be made thinner, which allows more light to enter the greenhouse.

Tips: how to bend a profile for a greenhouse with your own hands correctly

Bending of pipes of any profile is carried out in two main ways - this is pressure on certain sections of the pipe, and pressure, combined with heating, on the section to be bent.

In the course of working with the pipe, the parts may not be located in the same plane, and the pipe may burst due to a strong bend.


Without knowledge of the technological rules for bending pipes, it will not work to get a high-quality frame for a greenhouse. In order to bend the profile correctly, its dimensions, cross-section and profile thickness, elasticity of the steel alloy and other parameters should be taken into account.

Namely:

  1. Wide pipes, with a wall thickness of 2 mm or less, are not recommended to bend at all, since in this case the pipe may burst. Pipes made of carbon steels or low-alloy alloys can spring back, i.e., after bending, they will partially tend to return to their previous state. When installing the frame of the greenhouse, it will be necessary to adjust such pipes on the spot, again bending in the right direction.
  2. Should be studied specifications pipes, in particular, the height of the profile, the thickness and length of the pipe, and, depending on this, it is possible to calculate the minimum and maximum bending radius of the pipe without damaging it. In case of difficulty in calculations, you can use online calculators, it is enough to enter all the parameters of the pipe, and the calculator will show to what maximum radius the pipe can be bent.

You can most successfully bend the pipe yourself if you use a profile bending machine, as industrial production, and amateur. If this is not possible, you can use a vice, clamping one end of the pipe, and put a larger diameter pipe on the other. With strong smooth movements, the pipe is bent to the desired radius.

We make a curved profile for the greenhouse with our own hands of the desired shape

For the construction of greenhouses used different type profile, it can be aluminum or metal, made of galvanized steel.

V middle lane In Russia, the use of a metal profile is more relevant, since it is more durable than aluminum.


Also used materials made from pipes of different sections and profiles (oval, round, rectangular).

Depending on the needs of the greenhouse, the shape of the profile and its bend may be slightly different:

  1. When choosing a galvanized bent profile for a greenhouse, you should read the certificate or document. You only need to buy a profile with a zinc coating thickness of at least class 1, and even better if the coating class is “P”. Such a coating will be reliably protected for many years from adverse environmental factors.
  2. The curved galvanized profile can also withstand significant loads, up to 90 kg / m2. A greenhouse from such a profile can be made by hand, and the profile can be connected to each other using bolts or welding. Everything drilled holes, as well as welds, must be carefully treated with cold zinc.

The 42nd profile is considered the most suitable for the greenhouse, but for reliability, they take the 50th profile, but it is more difficult to work with it. If the greenhouse involves polycarbonate coating, then in this case, the dimensions of the greenhouse for the convenience of work should be adjusted to the dimensions of the polycarbonate sheets. If it was not possible to find a galvanized bent profile, then it can be replaced with curved pipes, which are interconnected by welding or using connecting strips.

Bending instructions and example: how to bend a profile for a greenhouse

It is best to bend the profile, especially if it is made of pipes using special machines, but at home it is not always possible to use them.


You can bend the profile a little differently:

  1. So that the pipe does not break when bent, it is filled with sand, the holes are plugged at the ends so that it does not spill out, and small holes are drilled in several places of the pipe to let out the heated remaining air inside the pipe. After that, the pipe section to be bent is passed through a homemade pipe bender, which is a pipe buried in the ground and filled with concrete. The pipe at the bend is pushed between them, heated with a blowtorch and bent to the desired radius.
  2. The second way to bend the profile is a little more difficult, but does not require much effort, and profile pipe even one person can bend. Marks are made on a pipe or other profile at regular intervals, after which cuts are made in these places with a grinder. After that, the profile or pipe is bent along them, and when it is ready, the cut points are welded and covered, either with cold zinc, if the profile is galvanized, or with paint.

After the profile is bent, in the first case, sand is removed from it, and the holes made are welded using spot welding.

When manually bending pipes or profiles, it is difficult to achieve an accurate radius. Also, with the manual method, you can only bend thin enough.

If the pipe or profile has thick walls, then in this case it is possible to bend the pipe or profile only on a special machine with a hydraulic drive.

Ways: how to bend a profile pipe for a greenhouse

At home, it is quite possible to bend the pipe yourself without using any special machines, for this you can use a manual profile bender, which can be bought in specialized stores. But, it should be borne in mind that when using a manual profile bender, significant efforts will have to be made.


There is a simple way with which you can bend the profile pipe:

  1. 5 pipe cuts are welded onto a long, strong metal beam (perpendicular to it), the central one should be the highest, usually its height is 250–300 mm, and the remaining 4 should decrease evenly in height. It is not necessary to make the central pipe higher, since in this case, when the pipe is bent from the profile, it may break.
  2. The beam itself is securely attached to a concrete base or to a metal table.
  3. A profile pipe is folded onto the beams welded on top and fixed in several places with a wire.
  4. A lever from a smaller pipe is inserted into the ends of the pipes and, using its strength and weight as a weight, the profile pipe bends.

The process of bending the pipe into an arc with this method is quite long and laborious, but the pipe will bend into an arc as a person needs. With this method, it is difficult to obtain a sufficiently large radius of the profile pipe.

How to bend a profile pipe for a greenhouse (video)

Thus, independently using one of the most suitable methods or even several, you can give the pipes and profile the necessary radius, and make a greenhouse or, for example, a greenhouse out of blanks. Such structures, made according to all the rules, will serve for many years.

Self-arrangement of a private plot may sometimes require bending a profile pipe for the construction of a greenhouse or gazebo. Some people think that it is impossible to do this without a special device, but there are several methods that can quite do the job.

The nuances of pipe bending

The term "profile pipe" means hollow products of square, oval and rectangular shape. Their round counterparts are also included in this definition, but they are used less frequently (more on types of pipes -). It is difficult to give a profile pipe curved configurations and at the same time maintain its technical characteristics, but it is doable if this is done on a special device using a hot or cold method.

The profile in this process is affected by two forces: inside- stretching, and from the inside - compression. To balance these efforts, apply several nuances:

  • When bending the pipe, you need to monitor its outer wall. When heated, it expands very much and may not withstand the load, which leads to its crack.
  • It is necessary to bend slowly, then the risk of a fracture will decrease.
  • After completing the process, check the edges of the pipe, and if they lie in different planes, repeat the bending process to align them.
  • When choosing a bending machine, you need to focus on the thickness of the pipe walls and its cross section.
  • The inner wall of the pipe after the process may resemble an accordion, this is normal, as there is a reduction.
  • It is necessary to start bending the pipe from the end, and not from the middle, otherwise it will be more difficult to change the profile.

Before bending, you need to practice on unnecessary pipes to prevent marriage.

How to bend profile pipes by welding?

You can bend the profile pipe in a semicircle using a grinder. It is used to make several cuts along the entire profile of the pipe. This way is as follows:
  • Fix the pipe in a clamping vise.
  • Make thin cuts in the places of the future pipe deflection.
  • Clean the cuts from chip dust, and carefully bend the profile along them.
  • Weld the holes formed during bending using welding machine. With a small pipe diameter, a soldering iron can be used for this purpose.
  • Clean and grind the formed profile bending points and treat them with a protective compound, it will protect them from corrosion.


With it, you can get a pipe of the desired radius. When choosing this method, you do not need to use a vice, the workflow is as follows:
  • Fix one end of the pipe in the ground and close it with any plug.
  • Fill the profile pipe with sand.
  • Heat up the blowtorch. Move it near the place of the intended fold.
  • Bend the pipe, but this must be done quickly so that the metal does not have time to cool, otherwise you will not bend it.


This "hot" method allows the use of water instead of sand.

Springy pipe bending method

This method preserves the integrity of the walls of the profile pipe. Before applying the method, preparatory work is carried out:
  • Spring preparation . It is made from steel wire. The diameter of the latter depends on the thickness of the pipe walls. For winding the spring, a square section blank is used, a wire is laid around it. The outer diameter of the spring must be smaller than the inner dimension of the pipe.
  • Template preparation . Pipe bending will be carried out according to a pre-made reference blank.
The deformation of the profile pipe is carried out by laying a spring in it, which will protect the material from fracture. The part is heated with a blowtorch, and when hot, it is deformed to the desired diameter.

Bending profile pipes on a manual pipe bender (video)

The video below shows how to bend profile pipes with a cross section of 25 × 25 mm and 20 × 40 mm in order to make a frame for a greenhouse from them.


Pipes come with a wall thickness of 2 mm. Homemade pipe bender is a welded structure. It consists of the base of two small rollers sandwiched between the uprights. In the middle of the structure rises a carriage made of corners. A square platform is welded on their upper part, into which a screw with a nut from a jack is inserted, and a removable handle is inserted on it. A handle is also attached to the first roller, with the help of which the pipe is fed to the machine. A third roller is provided inside the carriage, the deflection arrow will pass through its center.

Pipe bending process:

  • Put the pipe on the two lower rollers and stretch it to the required distance by scrolling the first roller.
  • Lower the middle roller by turning the knob.
  • Pass the entire pipe to the marked mark in one direction. It will become slightly arched after rolling.
  • Perform the previous action only in the other direction, lowering the middle roller below. The pipe remains in the device and must be returned to its original position by turning the handle on the lower roller in the opposite direction.
  • Run the pipe a third time through the pipe bender. The arc of its bend will sharply increase.
  • Repeat all steps for the 4th time.
The result will be a rather impressive radius of pipe deflection, so you can prepare the required number of profiles.

In the next video, you can clearly see how you can make and use a pipe bender with your own hands:


The described methods using sand, welding and springs are used for special occasions v household. If you need to bend pipes often or you plan to build a large building with them, then it is better to purchase a profile bender or make it yourself. When using a pipe bender, the process is faster, the profile is correct without unnecessary kinks.

If you are building or renovating a home, you may be faced with the need to bend various metal structures. The arrangement of an arch for grapes or a greenhouse will not do without bending the profile pipe. This is not the easiest and simplest task. After all, the pipe can not only be deformed, it can simply crack, and in the worst case, flattening will occur. You will either have to do welding, or just get rid of this pipe.

Profile pipe bending technologies

There are several basic technologies for performing deformations. Let's consider each of them:

  • use of a profile bender;
  • the use of a pipe bender;
  • using traditional methods.

The use of a spring is to some extent similar to the method with water. It is specially compressed, wound, for example, on a metal or wooden rod, and inserted into the pipe. The thickness of the wire from which you will make the spring should be about 2-4 mm. Just keep in mind that it will then have to be removed. They take a soldering lamp and carefully heat the required area, then quickly begin to bend. In this case, it is desirable to use some kind of emphasis (template) suitable sizes. After reaching the desired state of the pipe, they wait for it to cool and, if possible, remove the wire. So you reduce the likelihood of accompanying deformations, avoid cracks, accordions and other undesirable processes on the pipe.


To bend a square pipe, craftsmen successfully use unusual way. At one end, the pipe is sealed, filled with ordinary tap water, taken out into the cold or thrust into the freezer (if dimensions allow). After complete curing, the product is carefully shaped into the desired shape. This technology is suitable for copper, brass and duralumin pipes.

And the last, environmentally friendly way to give the product the desired shape is associated with bending with sand and salt. As you know, they are used for deep heating in bronchitis, inflammation of the joints. These substances have the property of maintaining their heat for a long time and are characterized by infrared radiation. If you took sand, then you need to prepare it well: rinse, sift, remove impurities. So you avoid incidents. The pipe is corked on one side, it is possible with the help of a wooden block and filled with heated sand. You can heat it in a pan, you can use a blowtorch or in any other way. Close the pipe on the other side and again, using a suitable template, deform the product to the desired angle. If something does not work out, heat the pipe with sand with a lamp. The action of this substance is similar to other fillers. This softens the pressure, and the product with less loss softly takes the desired shape.

As you can see, there are a lot of ways to bend a profile pipe. Moreover, it is not necessary to use expensive equipment.

It is quite possible to bend a pipe from a profile on its own and without the help of rather expensive machines. Therefore, if you have a need to bend a pipe, then a special article on the site will allow you to learn how to bend a profile pipe at home without a pipe bender.

Bending a pipe with a grinder

In order to bend the profile pipe, you will need to use a grinder and a welding machine. Below we describe the details of such a process.

  • Before starting this work, the pipe should be fixed (using a vise). This procedure is needed to find the product in the same plane. If there is a weld seam on the pipe, then position it with outside bend. This must be done without fail otherwise the metal will disperse.
  • It is necessary to determine the calculation of the radius of the future bend and clear the place of this bend. To do this, you need to use a grinder and make several cuts along the length of the marks. After carrying out this work, you can easily bend the pipe.
  • The resulting cracks should be welded, then they should be cleaned. This work must be done slowly, and with special care. Thanks to this, you will not spoil the product, and the resulting result will please you.

Pipe bending with a spring and a blowtorch

In this article we are talking about how to bend a profile pipe. Here we give those methods that can be used if there is no special device designed for this purpose. So, in order to bend a profile pipe in the following way, you need a steel wire 2 mm thick. It needs to be shaped like a spring in order to pass deep into the pipe. It should be said that such a spring should not dangle inside the profile pipe.

In order to bend the pipe, you can buy a ready-made spring, which will be designed for bending pipes. Then you will need to place it in the pipe, and mark the place of the bend. Next, heat the product with a blowtorch. After the procedure, you can easily bend the pipe with a grinder. If the result does not please you, then you can fix it by redoing your work again, but with more accuracy.

Pipe bending with sand and a gas burner

If there is no pipe bender at home, and the profile pipe needs to be bent urgently, then use improvised means. In this part of the article, it is worth talking about how to bend a profile pipe without a pipe bender using a gas burner and sand. It must be said that this method will give the pipe the desired bend without the appearance of cracks and deformations on it.

  1. To carry out this work, you will need sand (preferably quartz), and gas-burner, drill and wooden plugs in the amount of 2 pieces. Next, perform the following steps in the prescribed order:
  2. If you did not have quartz sand, it is quite possible to use the usual one, having previously carried out the procedure for cleaning it. Sand should be sifted and dried by heating it with a burner or fire. Heating must be done after the complete cessation of its smoking. Ready sand should be cooled and poured into a clean bowl.
  3. One end of the pipe must be closed with a wooden plug. Next, we pour sand into the pipe, and we also clog its second edge with a second plug. Remember that such a filler will help to avoid various deformations and the appearance of cracks. If the pipe is empty, then it will deteriorate.
  4. It is necessary to make a small hole in one of the plugs so that air can escape from it during the heating process.
  5. Now you should make a mark of the place where the pipe will bend and heat it with a burner.
  6. Next, we give the product the shape we need.

When carrying out this work, it is necessary to ensure that the metal does not overheat. This can lead to the appearance of scale, and this material will lose its original quality. When the pipe reaches its desired shape, the wooden plugs should be removed from the holes, and the sand should be poured out. For easier removal of plugs, you need to slightly heat the ends of the pipe.

Additional pipe bending methods

There are a large number of methods for bending profile pipes without a pipe bender. consisting of special materials that you can apply. Let's list them below for our readers.

So, in order to bend a pipe made of copper (or brass), you need to use water and exposure to low temperatures.

  • One end of the pipe should be plugged.
  • Then you should fill the product with water and close the other end of the pipe.
  • You can fill it with either rosin or lead.
  • Now it is worth placing the pipe in a cold place or in frost in order for ice to form.
  • After that, the pipe will acquire the necessary shape.

In order to bend on a pipe consisting of metal-plastic, you need to take ordinary table salt.

  • Before starting work, salt should be heated in a pan. This procedure must be carried out until the salt crystals begin to explode.
  • Then we pour salt into the pipe. As soon as it gets inside, our product will take the desired shape and will easily bend.

Finally

Now you have learned how to bend a profile pipe with your own hands. In general, remember that various methods pipe bending can allow this work to be done at home, without the use of expensive equipment and without the services of those people who do it professionally. We hope that our tips will help you bend the profile pipe using handy tools. So keep an eye on the process of your work and try to do it carefully and without haste. And the result will definitely please you.
