Drywall has already become an integral part modern renovation. From this finishing material you can create various complex shaped 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 necessary for installing plasterboard sheets.
Therefore, the question “how to bend a profile?” remains very relevant. If everything is done correctly, then in the end you can get exactly what you wanted.
Structures made today from plasterboard often contain a variety of curved and shaped elements. They are especially often used when installing 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 necessary in other situations:
- arch installation. Here the profile should be bent into an arc;
- creating a unified composition of walls and ceiling when the figured elements of the ceiling flow onto the wall;
- installation of niches with curved elements;
- creation of a figured partition. It can be decorative, contain complex bends and curls or be straight.
Drywall arch
In any of the above situations, in order for the installation of drywall to proceed according to the specified pattern, it is necessary to bend the profile. If you do the whole process correctly, then the subsequent installation of plasterboard sheets will be quick and easy, and the end result will be pleasing to the eye for many years.
As you can see, in almost any repair using drywall, bending profiles at different angles is a load-bearing necessity.
Flexion metal elements frame for plasterboard sheets is carried out according to the diagram. Therefore, in order to correctly bend the profile, you need to read the corresponding instructions. We will 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.
The list of necessary materials in this situation will include:
- metal profiles;
- fasteners. Here you will need self-tapping screws.
Don’t forget to protect yourself when carrying out work. So, you will need protective gloves that will prevent wounds and scratches on your hands. In addition, you may need safety glasses.
Having such a set of materials and tools at hand, as well as taking all precautions, the procedure for giving the profiles the required shape will take you 20 minutes at most.
Let's get started
On at the moment There are two main types of profiles: guides and rack-mount.
Pay attention! Only the profile guides can be bent, since the rack ones are used to support the main weight of the plasterboard structure.
In addition, when creating an arched opening, you can use a special arched profile.
Regardless of which frame element will be used, bending methods can be applied to all of them. It is necessary to bend the profiles before they are installed.
The bending of the element is achieved through cuts at right angles. The angle here should be 90 degrees, i.e. direct.
There are two options for making cuts, which depend on which part will be used for further installation of the frame element:
Side cut
- a cut 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 the stiffeners to be preserved intact. This method is great for making arches, semicircular elements or a circle;
Pay attention! When using this method, you need to remember that the smaller the bend radius is needed, the more often you need to make cuts at an angle of 90 degrees.
- the incision is made at the base 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, shaped elements are made on the ceiling. Therefore, it is necessary to begin 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:
Cut on the side and base
- We apply markings along the first level of the frame or wall surface (in the manufacture of decorative shelves). This stage is mandatory, since without marking it is impossible to make complex shaped elements;
- take the guide profile and shorten it to the length we need;
- to shorten the element you need to use metal scissors;
- Next, depending on the cutting method, we make a cut at a right angle of 90 degrees. The cuts must be strictly parallel to each other, otherwise the element will not be able to bend. The pitch for the cuts may vary depending on your needs. But often it is 5-8 cm;
- We make cuts where you need to make a curl or along the entire length of the profile;
- apply the cut profile to the marking line;
- After this, we fasten the finished element, bending it as the action progresses. You need to fasten it with self-tapping screws. Here you should be extremely careful not to cut yourself on the sharp edges of the metal product;
- the element must be secured sequentially, carefully giving it the desired shape.
Attaching a curved element
Pay attention! 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 smooth surface of the ceiling or walls.
To give greater rigidity and strength to the figured element, we install rack profiles inside it.
After this, you can install the drywall. The main thing here is that the pieces from a single sheet are cut accurately required size. If they don't fit slightly, they can be cut to the correct length with a drywall knife.
By following these instructions, you can correctly bend any metal profile and give it absolutely any shape.
Things to remember
To ensure that the procedure for giving the elements of the metal frame the required shape goes correctly, it is necessary to adhere to some rules and recommendations, because only in such a situation will you be satisfied with the end result:
Fastening sheets
- 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 construct;
- strictly follow the steps given in the instructions;
- To create shaped 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 any 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 shaped element. Cutting their sides at right angles will be a little more difficult;
- curvilinear frame construction must correspond to the parameters of the element that were drawn on the drawing;
- installation of drywall on a curved profile should be carried out using self-tapping screws;
- The greater the bend of the profile, the smaller the step will need to be taken when installing drywall. This way you will achieve maximum attachment of the sheets to the frame, without the formation of cracks;
- use the right tools, especially for forming cuts on profiles. This way you will avoid damage to your hands and quickly cope with the entire volume of work.
By adhering to these rules, you can easily create unique shaped elements from plasterboard at home, giving your home a new, original look.
As you can see, there is nothing complicated about bending the metal frame elements. The process of giving the desired shape to plasterboard sheets is much more complicated than for profiles. You just need to strictly follow all the steps of the above instructions and the result will be excellent!
One of the popular types of construction metal products is a profile, which is oval, square or rectangular section. Widespread in the manufacture of metal structures, load-bearing structures, canopies, prefabricated frames received rectangular and square steel pipes. They are used in private housing construction (for the construction of fences, greenhouses, various gazebos and canopies).
The only drawback is the more complex process of bending them and giving them the desired shape. Let's take a closer look at how to bend it yourself profile pipe.
Manual bending
Let's talk about how you can bend pipes manually.
Hot bending method
The simplest manually is “hot bending”. This method allows you to obtain fairly smooth lines and the required shape without significant changes in the profile geometry. To prevent flattening during bending, the pipe is filled with dried quartz sand. To do this, a wooden wedge plug is hammered into one end and, after filling it with dried sand, the other end is also plugged with a similar plug. A small hole is drilled at one end of the pipe so that air can escape freely. Next, locally heat the required area using gas welding and give the desired shape. As a replacement for gas welding for heating, you can use blowtorch or gas burner.
The pipe should not be overheated, as this will inevitably lead to the appearance of scale and a decrease in the quality of the metal. Repeated heating also degrades the quality of the metal, so try to bend the metal the first time.
After obtaining the required shape, remove the plugs and pour out the sand (it can be reused if necessary). The easiest way to remove plugs is to heat the ends of the pipe with a torch. As they burn, the wedges fall out easily.
Using sand for packing avoids breaks and improper deformation. With a certain skill, you can bend the profile quickly enough, so you shouldn’t even try to do it without filling it with sand - you’ll just ruin the material.
It should be remembered that galvanized pipes cannot be bent in this way, because during heating, the zinc layer will burn and cease to perform its anti-corrosion function.
Bending method using welding
An alternative way to do manual bending at home is to use welding and a grinder. In this case, the work is done as follows:
- First you need to calculate the required radius of curvature.
- Next, to facilitate the process, using a grinder, uniform transverse cuts are made along the entire length of the bend on three sides of the profile (on the outside of the planned bend).
- At the next step, the profile pipe is given the required shape, the cuts are welded and the weld seams are ground.
Bending using pipe benders
A pipe bender is a device or machine designed to change the shape of a pipe. The equipment allows you to perform bending in accordance with the required shape and size. Its correct use allows you to maintain the strength characteristics of the material, while avoiding flattening and creases.
Depending on the type of drive, pipe benders are:
- Manual.
- Electromechanical.
- Hydraulic.
Main advantage hand tools is simplicity and relative cheapness. But working with them requires significant physical effort, so using them for large volumes of work is quite tiring.
Hydraulic and electromechanical equipment does not require significant effort during operation, which allows you to bend pipes quickly and accurately.
Choosing the optimal bending method
If the amount of work is one-time and small, then it would be optimal to use “hot bending” or manual machine. As an option, you can not purchase a manual pipe bender for one-time work, but rent it.
If you constantly need to bend profile pipes, then it makes sense to purchase equipment or make it yourself.
You can also find a company that has specialized equipment - profile benders, which allow you to quickly and efficiently complete any amount of work and give pipes a complex and intricate shape. If the price of services suits you, then this option is most preferable for a large volume of work.
By choosing the optimal method and carefully completing the work, you will get more attractive and easy-to-use pipes (compared to round ones), which will be widely used in the process of improving the area of your home.

We bring to your attention a story that shows the work of a homemade pipe bender.
Popular building material Drywall is used to create perfectly smooth surfaces. But now they have begun to use high-quality plasterboard designer designs curved shape - arches, multi-level ceilings, niches. You can create similar decorative components yourself, but first we’ll figure out how to bend the drywall profile to get the desired shape. In addition, you need to learn how to make durable metal frame for securing a curved part.
For what purposes do you need to bend a plasterboard profile?
Drywall (gypsum plasterboard) is used to create various shaped elements. Modern installation of suspended ceilings is not complete without the use of this material. When creating a ceiling design, the following elements are used:
- Circles of various diameters
- Regular squares or rectangles
- Waves, steps, sun and many other elements
In addition, the profile will need to be bent in the following cases:
- If a high arch is formed, the profile can be bent into an arc
- When the ceiling is formed as a single composition with the transition of individual shaped components to the walls
- When installing a niche that has a curved element
- When creating an arched partition with a complex bend

Required tools and materials
Working with durable sheets requires the necessary set of accessories. To bend correctly metal parts, make the necessary cut on one of them, and also ensure their high-quality installation, we use the following accessories:
- Screwdriver
- Metal screwdriver
- Pencil, tape measure and precise building level
- Special scissors for working with metal
In addition, the following items may be needed:
- Durable metal profiles on which we will fix the gypsum boards
- Various fasteners, such as self-tapping screws
When bending sheets, you need to take care of your own safety; your hands should be covered with protective gloves to avoid various scratches and abrasions. Special safety glasses may also be useful for your work. The procedure for creating structures from profiles of the required shape will take you 20 minutes if you follow the recommendations.
Let's start bending and securing the profile
How to bend a drywall profile correctly? The guide profile can be bent, since the rack-mount ones are designed to support the main weight of the future structure. When creating an opening for an arch, you need to use a special arch profile.
All profiles must be bent before their actual installation. Right angle cuts will help give the profile the desired shape. There are 2 execution methods, depending on which part metal profile will be used to install a durable frame:

The smaller the radius of the upcoming bend, the more often the cuts need to be made. Often the ceiling is decorated with figures; sometimes the wall can also be decorated with various figures. In this case, bending should be done after the formation of the first level frame is completed. The profile bending scheme is as follows:
- We make markings for the first frame level. This is necessary, since without this action it is impossible to perform complex figured elements;
- We cut the desired profile to the required length. To perform shortening, you need to use special scissors for metal;
- We make cuts at right angles, one must run parallel to the other, otherwise it will not be possible to bend the element. The step for their implementation may vary, but it is in the range of 50-80 mm;
- We make cuts along the entire length or strictly in the place where the next bend needs to be made;
- We try on the cut material to the finished marking lines;
- We install the finished fastener, bending it as it is fixed;
- We fasten all the components, giving them the desired shape.
Before bending begins, the structure is fixed with self-tapping screws. This is an easy way to secure the future frame to create the right decorative element.
To install a structure with many curved shapes, you may need help, since it can be difficult to install a bulky part yourself. You need to watch carefully while working so that everything is done according to the diagram and the desired bend shape is obtained.
When fixing a frame containing curved shapes, each detail must be checked with a building level, because it is very important that all components are placed in a single plane.
Home renovation, in particular the renovation of a private house, often requires the use of pipes, and not always perfectly straight ones. In such a situation, the question arises: how to bend a pipe without a pipe bender at home? If you know all the tricks of this process, then it is quite simple to do.
Methods for bending a metal pipe at an angle of 90°
Metal is a fairly strong material, but special impact Quite easy to bend. Today there are several bending methods metal pipe with your own hands.
Modification of the profile pipe
This type of metal structures is often used for the construction of greenhouses various sizes and purposes, as well as gazebos and other buildings on the site. The main feature of the building material of such a pipeline is that when bent it is very easy to damage, for example, it can easily flatten or crack. The way out of this situation is quite simple. Its cavity must be filled with dry fine sand or water (later the water must be frozen). It is these actions that will eliminate the possibility of damage to the pipe and achieve the desired result. The same technique is suitable for both duralumin and brass pipelines.
How to bend a square profile pipe?
If you have a square pipe with a small cross-section in your hands, you can easily bend it without heating. However, it is still advisable to fill the cavity with sand or water. Unlike the usual round blanks, you will need a rubber mallet.
The pipeline itself must be placed on two reliable supports. After this, using the mallet directly, bend the product, and all actions must be performed very smoothly and carefully to avoid possible damage. If you need to achieve a large enough angle of curvature, the material can be heated at the intended bend to facilitate the process.
Rules for bending metal-plastic
Exactly metal-plastic pipe Most often used for arranging a heated floor system. To ensure the efficiency of the system, it is necessary to ensure parallel operation of the pipeline with the heating system.
Features of laying heated floors imply the presence large quantity folds. However, they are not available for free sale. You have to make the bends yourself, and for this you need to know all the secrets of the material and the procedure.
Just as in the case of a metal blank, there are several ways to obtain the required turn:
- the easiest and cheapest method to bend a pipe on our own, without the use of improvised means. To do this, the building structure should be held tightly in your fists and bent smoothly. Try to exclude the possibility of a strong bend. There is a standard for this, which assumes the presence of 15° curvature for every 1-2 cm of a metal-plastic workpiece;
- for another method, you need to take care of the availability of pieces of wire with which you need to fill the cavities. This will allow you to achieve a smooth and even bend in the shortest possible time;
- since for a metal pipeline, dry fine sand can be used as a filler, which must be poured into the cavity and the pipe holes must be closed with plugs. One end of the building structure needs to be fixed, and it is advisable to do this quite reliably and firmly, and then, using a blowtorch or gas torch, heat the place of further bending. Checking the readiness of the material to change shape is checked with a piece of paper.
Features of bending polypropylene pipes
There are situations when it is simply vital for you to bend exactly polypropylene pipe. However, the opinions of manufacturers agree on one thing: it is undesirable to do this. But if you cannot do without this, use one of two possible methods.
The main methods for bending polypropylene material:
- The first method involves the same heating of the bend. Should be used for these purposes construction hair dryer. The optimal final temperature is 150°C. Next, it is recommended to protect your hands with heat-resistant gloves; bend the product to the required shape. The main thing is not to forget about the basic rule: the thickened wall of a polypropylene structure must be placed with outside bending Now wait until the material has cooled completely and inspect it carefully. There should be no dents or cracks on the surface;
- the second method is cold. Anyone can bend such a pipe with their hands, but the bending radius should not exceed 8 diameters of the pipe used, otherwise you can simply break it.
How to effectively bend a plastic pipe?
Instructions to help you bend easily enough PVC pipe, includes several points, following which you can give the plastic pipeline the desired shape at home without outside help. So, to work with PVC pipe you need to do the following:
- Purchase a fibreboard, from which you will later need to construct a special frame. You need this frame to give plastic construction a certain shape.
- After giving the slab the desired shape, it needs to be properly sanded. It is better to use fine sandpaper for this.
- The next step involves forming silicone into a shell of suitable shape and size for your plastic blank. This shell serves as a fastening for the PVC structure into a pre-prepared frame. In addition, she is able to perform protective function from scratches, chips and other mechanical damage, to which the surface of a plastic pipe is exposed.
- Now you should place the object itself in the prepared protective shell.
- The next step involves heating the bend area. Plastic exposed to high temperature, begins to soften and settle on the installed frame. Such actions will ultimately lead to the formation of the desired shape of the plastic blank.
- After giving the shape, it needs to be given time to cool. Ten to fifteen minutes is enough for this. Only after this can you safely remove your modified PVC pipe from the frame, after which the building structure must be left again for complete cooling.
It is quite difficult to achieve an ideal pipe bend, regardless of its material, at home. However, if you carefully study the theory and conduct more than one experiment on unnecessary sections of such a pipe, you will clearly understand in practice how to bend a pipe without a pipe bender and will be able to do this at any time convenient for you. Be sure to use our tips to get the job done as correctly as possible and without major losses.
