Profile for drywall: sizes and types, nuances of choice for different finishing materials, features of fasteners. Types and sizes of profiles for plasterboard Profile for plasterboard application

Drywall has long occupied a strong place in the building materials market. Typically, such material is attached to the sheathing.

The main structure is a frame made of vertical and horizontal profiles. Their range is classified by type, size, purpose and other characteristics.

Peculiarities

A modern profile for gypsum boards provides enormous opportunities for creating a variety of geometric shapes and shapes. It helps to avoid monotony in the interior. With its help, you can make an original suspended ceiling and any module, sheathe walls, assemble an internal partition, partition and many other structures.

The unification of profile structures makes the work of professional craftsmen and home craftsmen easier.

The metal frame for covering with plasterboard sheets is much stronger than a similar structure made of wooden beams.

The profile is made on special machines, which allows for accuracy in size and ideal lines. In addition, metal is more durable than wood.

The peculiarity of calculating and choosing profile sizes is that they must be made based on several factors.

One of them is the thickness of the plasterboard sheet, which affects the overall load of the structure. This is especially important when choosing rack profiles.

If a single-layer plasterboard profile is intended (load up to 8.5 kg per m²), it will be sufficient to use products measuring 50x50 or 50x40 mm. If the expected load is higher, a profile of 65x50 or 75x50 mm should be used.

Kinds

To avoid mistakes with the choice and confusion in the diverse range of profiles for drywall, certain knowledge on their types may be required. They differ from each other in dimensional characteristics, metal thickness, cross-sectional shape and the raw materials from which they are made.

The main profiles for creating frame bases for ceilings and walls come in several types.

Guide

This profile is marked PN (UD), which means “guide profile”. Its cross-section is U-shaped, the side walls are smooth, and there are holes for fastening in the back.

A guide or starting profile is used to create the main support (for racks and lintels).

It is attached around the perimeter of the structure, and subsequently the remaining components are installed into it.

Rack-mounted

This option is marked PS (CD), which means “rack-mount profile”. It is inserted into the guides, plasterboard sheets are attached to it. In this regard, the main burden falls on him. That's why the rigidity of the rack profile should be maximum.

Its cross-section has the shape of the letter P, but the PS design is equipped with additional shelves and stiffeners.

Ceiling

It is marked PP and PPN, which means “ceiling guide profile” and “ceiling carrier profile”. The PP and PPN sections are shaped like the letter P, but have smaller dimensions than the wall profile. The ceiling profile has shorter shelves and stiffeners. The small height of the shelves is due to the need to reduce the “take away” of height from the room by the plasterboard ceiling.

Reinforced for ceiling

It is marked UA, metal thickness is 2 mm. Used to create reinforced frame bases for suspended ceilings.

In addition, it is used as part of the structure for fastening window and door frames.

Arched

It is a type of rack and guide profiles. Denoted by the abbreviation PA (CD). Used to assemble structures with radial bends.

The main distinguishing features for this type are pronounced perforation and the presence of side slits, which provide the opportunity to bend the profile. In some cases, an arched profile can be made independently by cutting the ceiling plinth shelves into sectors and then bending them in a given radius and direction.

Septal

• Guide. It is marked UW. The principle is similar to the UD profile, but has slightly different characteristics: greater height (40mm) and width (usually 50, 65, 75 and 100 mm).
• Load-bearing or rack-mount. It is marked CW and has a shelf height of 50mm.

Additional profiles and accessories

When creating structures that use plasterboard and metal profiles, you cannot do without additional elements. Their range is varied and includes several varieties.

Angular

It has a rectangular cross-section with a slightly protruding center part.

It is used to form corners of plasterboard structures.

Corner profiles also have several subtypes:

• Both shelves are perforated with large holes, which allow the corner to become part of the plaster layer and thereby be held securely.
• With mesh, which is glued along the edges of the profile in the form of strips. As a result, enhanced adhesion is achieved with subsequent finishing measures.
• On paper. In this case, 2 metallized strips are glued onto high-density paper. Such elements are used where a small load is expected (in window openings, edges of shelves and niches).

Mayachkovy (PM)

It is used as a beacon or support guide in order to obtain a more even surface when plastering. The most widespread are beacon profiles with a length of 3 m and sections: 22x6, 23x10, 62x6.6 mm.

Perforated hangers

Metal

Metal anchor suspensions for ceiling profiles are used for the design and installation of suspended ceilings.

With the help of anchor suspensions it is easy to adjust the height, as well as align the ceiling plane.

Connectors

A single-level and two-level connector for a ceiling profile is called a “crab”. It is a plate with clamps for fastening cross profiles.

Used for installation of suspended ceilings.

Extension

The profile extension is a small bracket measuring 110x58 mm for splicing two sections of the same size.

Materials

Drywall profiles are made of steel and aluminum. Steel profiles (plain or galvanized) have become more widespread in finishing work.

Aluminum, despite its excellent characteristics, are much more expensive.

Dimensions

For the convenience of installation work and to make it easier to select the material for the job, the standard system of sizing profiles for drywall provides several options for the main parameters. Guide profiles come in different lengths and widths, but the main dimensions of the PN profile are as follows (the first parameter is the width, and the second is the height):

• 28 x 27(for wall and ceiling structures);
• 50x40mm, 65x40mm(some manufacturers have a CD profile width of 60 mm);
• 75x40mm, 100x40mm(for partitions).

As for the length, it is usually available in four options: 2.5 (2.6), 3, 3.5 and 4 meters. If a longer profile is required, for example, 5 m, it is made to order or connected from separate sections. The wall thickness depends on the manufacturer; it can range from 0.4 to 0.6 mm.

Rack profiles are usually produced in four main sizes:

• 50x50mm;
• 65x50mm;
• 75x50 mm;
• 100x50mm.

Their standard length assumes sizes of 2.5 (2.6), 3, 3.5 and 4 m. Many rolled metal manufacturers accept orders for products of longer lengths.

Ceiling profiles have dimensions of 60x27 mm (ceiling guide) and 27x28 mm (ceiling carrier).

What to cut with?

Before you start working with a metal profile, you need to find out what can be used to cut it. It is necessary to prepare the appropriate tools. Typically, a jigsaw, grinder, hacksaw or metal scissors are used for this.

Jigsaw

A metal file is installed in the tool. Cutting begins from one of the profile ribs. First, the back part is sawed, and then the side edges. When using this method, high quality cutting and the absence of burrs are noted.

Bulgarian

An angle grinder (angle grinder) will be an excellent assistant in profile cutting. Using this tool, the cut will be faster than using a jigsaw.

However, working with an angle grinder requires certain skills. If you lack experience, there is a high probability of leaving the marking line and getting an oblique cut.

Hacksaw

When working with power tools is not available, an ordinary hand hacksaw for metal comes to the rescue. In this case, you need to start cutting from the edge, then you need to move to the back and side parts of the profile.

The inconvenience of this method is that during the cutting process, the profile may be deformed under mechanical stress. In addition, the time and energy costs are much higher than when working with a jigsaw or grinder.

Metal scissors

This is a fairly simple and most common method of cutting metal profiles. The cut with scissors is made strictly along the marking line. Using a high-quality tool is one of the guarantees of obtaining a beautiful cut.

The most difficult thing about this method is the likelihood of leaving the marking line when passing an edge.

For a perfect result, a little training may be required or a combination of cutting the ribs with a hacksaw and then cutting with scissors.

Despite the fact that the dimensions of the profile elements are fairly standardized, it is advisable to form a set of profiles to create a metal frame from the range of one manufacturer. Otherwise, you risk encountering some inconsistencies, such as: different parameters for the length, width and depth of the profile, metal thickness, as well as its quality. At the same time, the risk of installing a metal structure with reduced strength increases significantly. This may affect the finished result of the work.

When choosing sheet thickness, you need to think about what the thicker the metal, the stronger the structure, but its cost also increases. Therefore, experts recommend optimizing all parameters and choose metal 0.5 mm for ceilings and 0.6 mm for walls. The thicker the metal, the more reliable the structure will be. An economical option using thin steel may not withstand significant loads.

The key to the strength and long-term operation of a plasterboard structure is the use of a frame made of special parts. They are profiles for plasterboard, connected to each other with fasteners, which are lightweight and can give the final product the desired shape and size.

Classmates

Types of elements and their properties

The production of profiles for plasterboard is carried out on a profile bending machine by rolling cold-rolled galvanized metal sheet. During the manufacturing process, products acquire stiffening ribs and mounting holes, which as a result ensures their strength and practicality, as well as resistance to corrosion. The structure itself, made using profiles, is not complicated and consists of vertically and horizontally located parts, selected depending on its purpose.

For the construction of partitions

The profile for plasterboard partitions is larger in size than its other type. The range of overall dimensions of products varies from 50 to 150 mm and is selected depending on the partition being built, the expected load on it, the need to install communications, and lay insulating materials. Partition profiles are divided into:

For decorating walls and ceilings

Almost all wall and ceiling structures are formed using two types of profiles - guide and load-bearing. To obtain curved shaped forms, a flexible profile for plasterboard is used. Description of each of them:

Additional details

In addition to the main varieties, there are various elements that help strengthen the structure, give it greater security, or facilitate subsequent finishing:

Note! The products of large and reputable manufacturers are made using the best quality steel, which makes its purchase more expedient.

Fasteners

Fixation of profiles to planes, as well as to each other, is carried out by products, which include:

• U-shaped bracket. A bent perforated metal plate, the purpose of which is to connect the frame being built with the walls and ceiling. To do this, the bracket is fixed to the surface to be finished in the middle, and a starting profile for drywall is attached to the ends;
• quick suspension It is used when a U-shaped bracket is not enough, and consists of 2 parts - a knitting needle with an eye at one end and the suspension itself. The parts of the product are attached to each other using a spring, which allows adjustment of the height of the suspension, which is the advantage of the element. This type of fastening has a drawback - after some time, the spring weakens, as a result of which the suspended ceiling may sag.
• crab connector. Makes it possible to fasten load-bearing profiles crosswise. To do this, the product is mounted in the profile, attached to it with antennae and self-tapping screws, after which a jumper is attached in a similar way, which is also fixed with self-tapping screws. To install one crab connector, it must be fixed with 8 self-tapping screws;
• CD connector. The purpose of the element is to lengthen the load-bearing profiles. To do this, they are inserted into the connector on both sides and fixed with self-tapping screws;
• two-level CD connector. A rare product used to assemble a frame attached to a wooden floor. The frame made using these fasteners turns out to be double: first, the first and then the second level of profiles are assembled, which is mounted in the usual way. The need to use a two-level connector lies in the need to compensate for changes in the size of the tree depending on the level of humidity and temperature changes.

Fastening metal profiles to surfaces, to each other, as well as screwing plasterboard sheets to them is carried out using piercing and drilling type self-tapping screws, equipped with nylon dowels, anchor wedges, and dowel nails.

How to choose high-quality profiles and fasteners?

When purchasing a profile, you should immediately check that it is level, corresponds to the declared size, and has no damage to the galvanized coating. In addition, products whose thickness is less than 0.55 mm cannot be used for arranging the frame. To purchase quality products, it is recommended to familiarize yourself with the types of defects:

• insufficient thickness of the metal, which entails the screws turning. If possible, you should check all types of drywall profiles using a caliper, or compare products from different manufacturers if the tool is not at hand;
• rust. If there are already traces of corrosion, then it will definitely spread further. Increased attention should also be paid to heavily lubricated products - this may indicate an attempt by the seller to hide any defects;
• incorrect rolling. To detect it, you just need to inspect a separate part - the profile will be out of shape and twisted. A similar problem can also arise if products are stored incorrectly;
• non-compliance with the profile dimensions for drywall specified by the manufacturer;
• sparse or poorly made notch, which contributes to poor screwing of screws;
• traces of corrosion on the surface of the fastener. It is also necessary to check the tip and heads, the slots of which should be clear. Plastic plugs for dowels should not have sagging, as they make it difficult to place parts in the holes;
• the presence of burrs on the surface of the drywall profile.

Thus, the variety of metal profiles and the range of fastening elements make it possible to select products for the most comfortable construction of a plasterboard structure. The main importance is a competent and balanced choice, timely detection of defects. Purchasing high-quality products and following the rules for their installation will lead to the speedy completion of work, and the result will exceed all expectations.

Types of profiles for drywall and their purpose: main classification

Manufacturers offer products of various shapes and sizes. To purchase everything you need to install a specific structure, you need to clearly understand what types of drywall profiles exist and their purpose. We invite you to get acquainted with the main classification.

Surface-plane profile for plasterboard

Can be attached to the ceiling or. Their configuration is standardized, but there are differences in the thickness of the material, the length and transverse dimensions of the product itself. Allows you to form a reliable frame for fastening drywall with the correct choice of standard size and compliance with installation technology. It is important to remember that the price of a profile depends on the size and type.

Drywall guide profile: distinctive features

Marked PN (UW). Is the starting profile for . The section is U-shaped. The walls are smooth. Acts as a support for various racks and jumpers. During the installation process, the remaining structural elements are put on it.

The guide profile for drywall can have different lengths (up to 4.5 m). The most popular is 3 m. Transverse dimensions are selected individually for a specific system.

Rack profile for drywall: design features

Marked PS (CW). It is installed inside the guide and is used to fasten other elements of the system. The rack profile for drywall is quite rigid. Capable of accepting significant construction. It has a U-shaped additional section with additional shelves for fixing other structural elements.

Attention! If the base is level, the rack can be attached directly to the wall or ceiling.

Plasterboard ceiling profile: main types

It can be a load-bearing PP (CD) or a guide PP (UD). Products with a U-shaped cross-section, but with smaller dimensions than wall ones to save space. To increase the rigidity of the ceiling profile for plasterboard, additional shelves and ribs are provided.

To fix elements, you can use a special one. Allows you to install ceiling structures of any shape and size.

Corner profile for drywall

To strengthen the outer corners of the walls of a plasterboard structure, it is possible to use a perforated corner metal profile. For its manufacture, metal with a thickness of 0.3-0.4 mm is used. The corners are installed on and covered with a layer of putty on top.

Partition load-bearing profile for drywall and photos of finished structures

For the manufacture of plasterboard partitions, the UW and CW profiles are used. The first allows you to form the skin of the structure. It is used to form the perimeter of the partition and provide the required configuration.

The partition profile for CW plasterboard allows for sufficient rigidity of the system. Sheets can be fastened on both sides.

We invite you to look at the photos that you can create:

Arched plasterboard profile

It is characterized by a complex design. It has side slits to ensure sufficient flexibility. Additional perforation increases the rigidity of the product.

Allows you to form a structure with radial bending. It is most often made from PP 60/27. The standard length of the profile for plasterboard is 3 m. The minimum bending radius of the concave element is 500 mm.

Auxiliary components for the profile frame for plasterboard

To install a system of the required size and shape, special components for drywall may be required; each element has its own specific purpose. You will need a connecting longitudinal bracket if you need to connect the elements.

You may also need to purchase a profile:

• basement to create restrictions around the perimeter of the cladding. The outer side is puttied;
• hat for installation of sheet metal. Attached to the base. Allows you to eliminate guides;
• L-shaped, if you need to install a finishing or starting strip in a wall with open ends;
• z-shaped to increase the rigidity of the system;
• beacon if the base needs to be leveled.

Fasteners

To fix the profile, dowels are used. They are hammered or twisted at the intersection of adjacent elements. The fastening elements can be:

• suspensions used during installation. If necessary, they can always be bent to obtain a plate of the desired size;

• crabs with a characteristic cross-shaped configuration. With their help, you can provide a rigid connection of intersecting planks;

• two-level brackets, relevant when installing a multi-level ceiling;
• corner brackets installed at the ends of structural elements.

Advice! When choosing fasteners, be sure to consider the dimensions of the metal element.

Criteria for choosing a metal profile made of plasterboard

In order for the mounted structure to last long enough, you need to choose the right metal profile for drywall. It is not only its appearance or size that deserves attention, but also other important points that are worth paying attention to.

Profile coating and material thickness

When purchasing, you should give preference to galvanized products. In this case, it is necessary to check the integrity of the coating.

The thickness of the product deserves special attention. The larger this parameter, the stronger and stiffer the metal profile will be and the higher its cost. If the thickness of the element is insufficient during installation and under operational load, it can change its geometry.

In 1980, a paper mill owner named Ostug Sackett had the idea of ​​creating a new building material from gypsum. At first, plasterboard sheets replaced plywood and chipboard in small houses. It was then that the interesting properties of this material were discovered. The joints of smooth and even cardboard are very easy to seal so that when painting or other types of finishing, they will be completely invisible. Breaking a marked sheet instead of sawing it is much easier. Constancy of dimensions eliminates cracks in joints... Drywall has proven itself in the construction market for a long time and has remained an integral part of repairs to this day.

This or that plasterboard structure must be supported by a frame made of strong and stable parts. These are guides and profiles of various shapes, which are connected to each other using special fasteners. They differ in purpose and application, as well as in size and quality. It is very important to make the right choice when purchasing, the result of the work will depend on it. After all, if you take a bad or simply unsuitable profile for a certain type of work, the design will eventually have to be redone. For example, a sheet on a partition will bend or “move” to the side, gaps at the joints will become visible, or a noticeable “wave” will appear on the wall itself. In order to avoid mistakes during repair and construction, you need to thoroughly study the types and sizes of drywall profiles. Find out exactly what material is needed to build a particular structure.

Rack profile (designated as: CD or PP).

Perhaps one of the most popular profiles for installing plasterboard on the ceiling. This type provides reliable fastening of the sheets. And if you choose the dimensions correctly, the work space will be used as economically as possible, leaving almost no waste.

CD or PP sizes:

• Profile length - from 2.5 to 4 meters
• Width – 60 millimeters
• Shelf height – 27-28 millimeters

Guide (UD or PPN).

Profiles are used for the construction of suspended ceilings. These elements are mounted over the entire area of ​​the work, because when securing sheets of cardboard, the drill passes directly through them. It is advisable to purchase guides that already have cut holes (perforated profiles). Then it will be much easier to carry out installation.

• Thickness – 0.55 millimeters
• Length – 3 meters
• Width – 27 millimeters
• Height – 28 millimeters

Profile (UW).

This type is very similar to the UD described above. It is used in the same way, but has different dimensions:

• Length – from 3 to 4 meters
• Width from 5 to 10 centimeters
• Shelf height – 40 millimeters
• Metal thickness – from 0.4 to 0.6 millimeters

Partition profile for plasterboard. Sizes and types.

Guide profiles (UD).

This type is suitable not only for ceilings, but also for plasterboard partitions and wall cladding. Let's take a closer look: in the back of these products there are holes for dowels (8 millimeters). The profiles are shaped like the Russian letter “P” and also vary in size.

Dimensions: (the first number is the width of the back, the second is the width of the shelf)

• 50 x 40 millimeters
• 65 x 40 millimeters
• 75 x 45 millimeters
• 100 x 40 millimeters

Rack profile (CD).

For partitions, this type has special grooves along the shelf. The two outermost ones are intended for screwing in self-tapping screws, and the one in the middle indicates the place of joints of plasterboard sheets. The width of the backrest of the rack-mount ones is identical to the guides. Because the PS is inserted into the PN.

Available sizes:

• 50 x 50 millimeters
• 65 x 50 millimeters
• 75 x 50 millimeters
• 100 x 50 millimeters

Enhanced (UA).

The profile is used for doorways in partitions. The main quality is strength and resistance to corrosion.

Profile dimensions:

• length – from 3 to 6 meters
• height of the side parts – 40 millimeters
• base width – 50 – 100 millimeters
• workpiece thickness – 2 millimeters

Corner – (PU protective).

Designed to protect the corners and ends of plasterboard partitions from mechanical damage. There are holes on the surface of the profile to allow finishing solution to penetrate into them.

• Length – 3 meters
• Section – 25x25x0.4 millimeters, 31x31x0.4 millimeters, 31x31x0.5 millimeters

Beacon profile (PM).

Used for finishing work. Attached using mortars to the required level. Helps to putty (or plaster) the wall smoothly.

• Length – from 2.5 to 3 meters
• Width – from 22 to 60 millimeters
• Metal thickness – from 0.33 to 55 millimeters
• Beacon protrusion – from 6 to 10 millimeters

Arched profile (PA) for drywall. Sizes and types.

This profile has cuts along the edges, thanks to which the metal product can be evenly bent and adapted to the construction of almost any complex structure. For example, make an arch or shelf in the wall of an unusual shape. There are both concave and curved types of arched profiles.

Dimensions of concave arched profiles:

• Radius from 500 to 5000 millimeters
• Length from 2600 to 4000 millimeters

Convex profiles can be:

• Radius from 1000 to 5000 millimeters
• Length from 400 to 2600 millimeters

Aluminum and galvanized profile for plasterboard. Sizes and types.

Profiles for drywall are made from different metals; let’s look at the most common types: aluminum and galvanized, as well as their characteristics.

Aluminum profile and its features.

This profile is not cheap, but it has excellent characteristics, so the high price is justified. Such profiles are good for constructing window frames or finishing household appliances. For example, if you need to make a niche for a washing machine in the bathroom. This product is distinguished by its long service life, durability and lightness. It does not weigh down the entire structure and is very easy to install. Plastic and resistant even to low temperatures. Builders recommend buying aluminum profiles for wall and ceiling cladding.

Profiles of this type are available in both cold and warm aluminum. Cold-formed is made of metal 4 millimeters thick, and bends without heating. It varies in shape (P, W, T, H - shaped). Withstands loads of up to 1.5 kN per 1 meter of wall.

Galvanized profile.

A galvanized profile is not inferior in price to an aluminum one. It is used to construct the base of the frame in rooms with high humidity - in the kitchen or bathroom. This is because it is resistant to rust and does not require additional treatment with anti-corrosion agents. Like aluminum, the profile is light and soft; screwing self-tapping screws into it will not be difficult. Galvanization is also used to create additional stiffeners if the plasterboard sheets are thicker than 12.5 millimeters.

There is also a plastic profile. Its purpose is to cover the joints of plasterboard sheets at the outer corners, giving a beautiful finish. And also, they cover the transition of drywall and other materials, for example, wood.

Additional accessories for fixing drywall.

In order to assemble the sheathing, you will need auxiliary parts:

• Two-level connector for CD profile. This part is sold in an unfolded, flat form and before starting work it needs to be bent in the shape of the letter P. It is used to connect rack-mount parts perpendicular to each other.
  
  
• Single-level connector for CD profile or “Crab”. They connect perpendicular CD profiles in exactly the same way. If the load is more than 20 kilograms, then you will need two self-tapping screws for fastening. Otherwise, the seals are simply bent.
  
• Direct suspension for a rack (supporting) profile. This is a bracket, the standard length of which is 12.5 cm. It looks like a strip of aluminum or galvanized steel with holes. Withstands loads up to 40 kilograms. It is attached to the wall with two dowel nails, then the edges are bent and the frame parts are already attached to them.
  
  
• Anchor suspension for ceiling carriers. Often called suspension with traction. Replaces the part described above if it is not long enough. Used on horizontal surfaces, for ceilings, for example.
  
  
• Extension. Needed to connect two carriers to each other. It has tubercles on the sides, this indicates where the profile joins. There are also two holes for screwing in self-tapping screws.
  
• Corner connector. It connects elements that do not form a cross. You can do without a connector. Cut the flanges of the profile that needs to be connected so that a tongue is formed, and screw it in place with self-tapping screws.
  
  

Accessories for fastening plasterboard.

Self-tapping screws are needed to connect all the frame parts and to install drywall. They also come in different types.

Tips on how to choose a profile and components for drywall.

1. Please inspect the profile carefully before purchasing. If you notice rust, you should refuse to buy such material. Once corrosion has already begun, it is impossible to stop it!
2. Check the thickness using a caliper. If it turns out to be insufficient, then during operation the screws will scroll.
3. Do not take a profile with burrs. In the process of work, injure your hands.
4. Take a closer look at the product from the end. If it was not stored correctly in the store, it may be bent. With such a profile, you will no longer be able to create a perfectly flat surface of the structure.
5. Keep in mind that it will be difficult to screw self-tapping screws into a profile with a weak notch.
6. Experienced builders advise double-checking whether the dimensions correspond to those stated in the instructions and in reality. Some manufacturers deceive buyers, especially regarding the length; it may be less than expected, by 2 centimeters.
7. The quality of fastening fittings should also be checked. Very often you come across self-tapping screws with a broken tip or with screwdriver notches clogged with metal.
8. Carefully inspect the plastic plugs of the dowels so that there are no sagging, otherwise it will be difficult to drive them into the hole, and sometimes even impossible.
9. Give preference, however, to a profile with dot perforations along the strip - it is more rigid and resistant to loads. This structure prevents the screws from slipping and makes it possible to screw them in at any angle.
10. Trust already proven manufacturing companies such as Knauf and Gyprok. But there are also our domestic manufacturers who produce profiles for drywall no worse.
11. Some cunning sellers try to hide defects by painting the profile and adding shine to it. Take a closer look at these options; you may not be able to buy them at all.
12. The product should not be flimsy and bend when pressed lightly.

And one last piece of advice at the end of the article. Do not skimp on high-quality profiles and components for them. As the famous saying goes: “The miser pays twice.” If you purchase a low-quality or damaged profile, then eventually, sooner or later, you will have to redo all the work. Somewhere the sheet will become a “bump”, somewhere the joints will become visible, and somewhere the structure will bend inward. Therefore, choose the material carefully; pickiness will not be superfluous here. Good luck and easy work!

Types of profiles for drywall. Video review.

The profile for plasterboard for walls has its own dimensions and is made so that there is no waste. Types of plasterboards, their markings, length and width. How to cut and lengthen a metal product - later in the article.

If you want to mount the structure yourself on vertical surfaces, then you need to figure out what profile is needed for plasterboard for walls. There are many types of metal products with different sizes and purposes. For wall lathing you need 2 main types of profiles and additional materials.

How to choose sizes

The modern market is overflowing with various types of metal strips designed for installation of gypsum boards. Depending on what kind of structure is being built, a certain type is used.

Metal strips are:

1. Guide for the ceiling structure PNP (UD).
2. Ceiling – PP (CD).
3. Rack-mount - PS (CW).
4. Guide – PN (UW).
5. Corner PU.
6. Lighthouse view.
7. Arched - PA.

The first 4 types are the main materials in creating a plasterboard structure. The rest are additional elements that create rigidity.

Each type has dimensions. The main ones:

To create sheathing for wall alignment, the following materials are needed: guide PN, rack PS.

Ceiling and rack guides are not used in the same design. They are designed to create different lathing.

What are the dimensions of the wall profile for plasterboard?

The following products are used to level the walls:

1. Bearing CW – 50x50, 75x50, 100x50, 125x50 and 150x50 mm.
2. UW guide – 50x40, 75x40, 100x40, 125x40 and 150x40 mm.
3. The length of the rack profile is from 2.6 m to 4 meters. The guide is produced 3 - 4 meters. There are differences in appearance: some have 2 strips for fastening, while others have an H-shaped cutout for cables.

Kinds

In wall construction, a rack type of PS is used, also known as a wall type - common in the creation of plasterboard surfaces.

It has slightly curved sides, and along the “back” there are 2 longitudinal channels.

Manufacturers make strips of such length that it is possible to make calculations and work without waste. The dimensions are:

• length 2.5-4 meters;
• width 6 cm - this is convenient when installing 2 sheets of plasterboard. 3 cm on 1 sheet and the same on the other. The joint is strong;
• the height of the side parts is 27 mm.

A guide strip used in creating a frame on a wall under plasterboard. This is the basis of the entire structure. The product is mounted on the floor and ceiling, a rack guide is inserted into it, fixed with dowel nails, the rack rails are secured into the guides with self-tapping screws, and a direct suspension goes from the wall to the profile.

Guide marking PN, European UW. It has a straight shape without bending. Product length – 3 meters, width 2.7 cm, side height 2.8 cm. Product thickness 0.5 mm.

Guides with holes for fasteners are available for sale.

Auxiliary profiles used for a rigid base under gypsum boards.

1. Corner - used when finishing the structure. This is to protect the corners from impacts.
2. Beacon products - used for plastering surfaces.

In addition to metal strips, to create a frame base for drywall, the following elements are used:

• Direct suspension is a perforated strip. It is folded on the sides, and the center is attached to the wall. A rack profile is fixed to this suspension; it can also be used in a metal frame on the ceiling.
• Connectors. These metal products are mounted when it is necessary to connect 2 profiles. Designed for rack-mount and ceiling profiles.
• Crabs are mounted in a ceiling structure, but if they create a complex vertical frame for a figured plasterboard structure, or reinforce the sheathing to hang heavy objects on the wall, then a crab (connector) is used.

To attach metal strips and direct hangers to the rough base, dowel nails are used.

Self-tapping screws are not recommended by craftsmen as fasteners to a rough base. Over time, it weakens the entire sheathing and it becomes loose. This has a negative impact on the finished HA structure.

When choosing metal products to create a frame base for gypsum boards, you need to pay attention to the manufacturer, its quality, how thick the metal is, whether there are traces of corrosion, and the evenness of the product.

What profile is needed for plasterboard for walls?

A guide strip made of galvanized metal PN (UW) is used as the basis of the entire wall frame. It is attached to the wall and ceiling so that the fixation is mirror-like, without shifting. They also need to be secured to opposite walls. You will get an even quadrilateral creating a plane. Fastening is done with dowel nails, a distance of 20-25 cm from each other. You need to retreat 5 cm from the edge of the profile and secure it with the first dowel-nail.

Afterwards, straight hangers are fixed to the wall according to the markings, serving as a holder for the rack element. Dowel nails are also suitable for fixation.

Rack-mount PS (CW) are inserted into the PN (UW) guides. They are fixed with self-tapping screws. The evenness of the plane is adjusted with a level and the rack-mounts are attached to the hangers with self-tapping screws.

For structural rigidity, transverse ones are made every 40 cm. They are cut from rack-mount PS (CW) and fixed to vertical rack-mount crabs.

Is it possible to adjust the sizes

Factories produce standard product lengths of 3-4 meters. However, in creating an even partition or wall with figured elements, different lengths of the product are needed. To do this, the metal elements are either extended or cut to the length required for the structure.

Profile cutting methods:

1. Scissors for cutting metal. You can cut the product evenly only along the marked lines. The disadvantage is the slightly curved edges after cutting. The cut strip is placed on a flat surface and leveled by tapping with a hammer.
2. A hacksaw is not a very convenient method. There are small shavings from cutting the product. However, the cut will be smooth.
3. Bulgarian. When working with an electrical appliance, sparks fly in all directions.

1. Cutting machine. A large electrical appliance used in large rooms with large volumes of work.

You can cut the profile without any problems using Soviet-made scissors.

Elongation of a metal element. In order to increase the product, 2 methods are used:

1. The use of an extension cord is a durable metal part coated with a protective layer against corrosion. It is applied to the edges of two planks and fixed with self-tapping screws.
2. Homemade extension cord from the PN guide. It is necessary to cut 10 cm from the product and attach it to the edges of the profiles. Fixation is done with self-tapping screws.

It is easy to adjust the length of the metal frame element. You just need to make accurate measurements and marks. You should not lose sight of millimeters, as they can play an important role in the evenness of the structure.

Profiles for creating a frame structure on the wall have certain dimensions and material thickness. They are coated with an anti-corrosion agent (galvanized) - moisture does not affect metal products. Before purchasing profiles, you need to know their number from the measured dimensions of the room.
