Profile for drywall. Sizes and types

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 various sizes and purpose. For wall sheathing you need 2 main types of profile and additional materials.

How to choose sizes

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

Metal strips are:

Guide for the ceiling structure PNP (UD).
Ceiling – PP (CD).
Rack-mount - PS (CW).
Guide – PN (UW).
Corner PU.
Lighthouse view.
Arched - PA.

The first 4 types are the main materials in creating a plasterboard structure. The rest are coming additional elements, creating 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:

Bearing CW – 50x50, 75x50, 100x50, 125x50 and 150x50 mm.
UW guide – 50x40, 75x40, 100x40, 125x40 and 150x40 mm.
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: on some there are 2 strips for fastening, and on others there is an H-shaped cutout for cables.

Kinds

IN wall structure They use the rack type of PS, also known as the 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.

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

In addition to metal strips, to create frame base under drywall, use the following elements:

Direct suspension is a perforated strip. It is folded on the sides, and the center is attached to the wall. A rack profile is attached to this suspension; it is also applicable in metal frame on the ceiling.
Connectors. These hardware 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 length products 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:

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.
Hacksaw - not very good convenient way. There are small shavings from cutting the product. However, the cut will be smooth.
Bulgarian. When working with an electrical appliance, sparks fly in all directions.

Cutting machine. 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:

Application of the extension cord – durable metal part, coated protective layer about corrosion. It is applied to the edges of two planks and fixed with self-tapping screws.
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.

Adjust length metal element frame is easy. You just need to make accurate measurements and marks. You should not ignore millimeters, as they can play a role important role in the evenness of the structure.

Profiles to create 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.

To create a reliable, rigid structure, profiles for plasterboard are used, which will ensure high-quality fastening of the sheet to the frame. Profiles form the basis of the design. Professionals divide them into two main classes - ceiling and partition.

Experts divide profiles into two main types:

guides;
rack-mounted

Profile construction

Each type is designed to perform a specific function. Profiles are marked according to the Knauf classification and are available in standard sizes:

ceiling guides – UD;
guides for partitions – UW;
rack ceiling - CD;
rack partition – CW.

At correct connection details different types a variety of devices are made from plasterboard, including suspended ceilings, boxes, partitions, and walls.

Release elements different sizes, sections and lengths.

Rack ceiling profiles

Suspended ceilings made of gypsum plasterboard are not subject to mechanical stress. However, the profiles should be light in weight and firmly hold the frame with drywall so that it does not collapse on the heads of household members. The ribs of the ceiling profiles provide rigidity to the structure frame.

Ceiling profiles- the most popular. They are most often used in construction and finishing works. Thanks to standard sizes After working with rack profiles there is practically no waste. According to the Knauf marking, they should be designated CD.

CD profiles can withstand the main load of structures. They are responsible for the rigidity of the frame, reliability, and quality of fastening of drywall sheets. Manufacturers produce them various thicknesses. Thin parts are less reliable and require installation large quantity fasteners.

The length of the rack CD is 2.7-4.5 m. In practice, three-meter or four-meter parts with a cross-section of 60x27 mm are usually used.

Guide ceiling profiles

Ceiling profiles are used to construct ceilings and are used in wall structures and various boxes to strengthen them. Guide profiles (UD according to Knauf) are placed along the perimeter of the ceiling or wall. Rack elements are inserted into them.

The ceiling guide profile performs important functions

The guide ceiling profiles form the basis for creating a plane that will be sheathed with sheets of plasterboard. The length reaches three or four meters, and the cross-section is 28x27 mm. The reliability of the part is ensured by its thickness; thin elements are not used in ceiling structures. They are suitable for creating wall frames.

If desired, metal products for gypsum boards are made according to individual order. All types are made from steel material with galvanization so that they provide strength and withstand the influence of temperature changes with an aggressive environment.

Profiles for partitions

Experts distinguish several types of profiles for partitions. Their use depends on the thickness of the future plasterboard partition.

Partition products marked according to Knauf UW are used to create partitions as guides. The length of the part is from two to four meters, the width is in the range from four to fifteen centimeters.

Rack-mount partition elements marked according to KNAUF CW are made with a notch, which facilitates cable routing. They are used to make partition structures made of plasterboard; they act as load-bearing elements of the frame.

Parts are oriented for use in vertical structures. Manufacturers produce CW with a length of 2.75-6 m and a cross-section of 50 (75,100) x 50 mm. The most common types of CW profiles are three or four meters long.

Arched, beacon and corner profiles

Arched products are made with cuts and holes that give them flexibility. Their dimensions are the same as those of other types of parts, the rigidity of which is much greater. The arched Knauf profile is bent to form an arc.

Parts are used to create arch structures

Despite its apparent simplicity, creating an arch for an arch is quite difficult. However, real professionals easily solve this problem.

The beacon profile is used to level the planes. For example, to perform plastering works. The length is three meters. The element is indispensable for creating smooth planes. For example, finishing slopes.

The Knauf metal beacon profile made hard and painstaking work easier. It is installed on a difficult place and creates a flat surface. The material from which the part is made increases its resistance to negative manifestations external factors, alkaline and other chemical influences.

Corner-protecting metal Knauf profiles are used to strengthen and level corners. They protect the ends of the partition from damage. Holes five millimeters in size were created in the planes of the part. This facilitates high-quality filling of the solution during puttying.

Additional mounts

To assemble the structure, fasteners are used, with which the parts are mounted to the surfaces of the ceiling or wall. These include the following:

crab connectors;
pendants;
brackets;
extension cords;
self-tapping screws

Craftsmen use “crabs” to create all types of structures, including suspended ceilings, partitions or walls. Fasteners are used to connect when parts intersect at right angles.

Anchors perform a vital function when attaching profiles to the ceiling. Connectors fasten sections of profiles together. The use of extension cords is identical to connectors.

To ensure that the gypsum board is securely fastened, special fasteners are used

To attach a plasterboard sheet, use self-tapping screws, dowels, and special screws. Their sizes are selected depending on the profile dimensions, design and type of surface to which the frame is attached.

Additional fasteners help craftsmen easily, quickly and efficiently assemble any plasterboard structure.

Tools

To make it convenient to work with drywall, use special tools that will help create the design required sizes, reduce waste, get the job done quickly and easily. For this you will need:

scissors for cutting metal;
connection pliers;
cutter;
divider

Metal scissors are used to cut parts of the required size. The segments are connected using special pliers. Experienced craftsmen The tool is called a staple profile.

To assemble the frame, holes are made in the parts and connected. This work is performed with a cutter, which punches holes for fasteners. The divider is used to connect profiles in corners.

High-quality material for profiles

When creating strong and rigid plasterboard structures, high-quality parts should be used. Solid base will create parts 0.6 mm thick, made of steel sheets. However, manufacturers produce profiles of thinner thickness, which do not always meet the requirements.

Quality parts ensure device reliability

Galvanized elements must withstand the influence of an aggressive environment, and to enhance the protective properties, polymer coatings are used. Such products are used even in extreme conditions.

Plastic profiles perform a decorative function. They are used in places where gypsum boards adhere to materials such as wood, glass, metal. Plastic products are easy to install and give the structure an aesthetic appearance.

Reading time: 8 minutes

The creation of a plasterboard structure begins with the construction of a strong and durable frame. In most cases, when choosing a material for it, preference is given to galvanized steel. Let's find out how to choose the right one constituent elements metal frame - profile for plasterboard and fasteners to it.

Types of metal profiles

The number of design options made from gypsum plasterboard is enormous, which required the creation of a wide range of types of metal profiles. They can be divided into several types:

Depending on the place of use - ceiling and wall.
According to the role performed - guides and carriers.
Depending on the nature of the structure being built - into profiles for cladding walls and ceilings or constructing partitions.
Depending on the cross section - angular, flat and U-shaped.

All profile types are shown in the photos below.

When installing gypsum boards, various combinations of metal profiles are used depending on the configuration and purpose of the structure. The parameters and types of parts, as well as the process of their manufacture are regulated by TU 112000-001-12586100-2009, TU 1121-012-04001508-2011, TU 112000-002-94835001-2013. They are made from galvanized steel (GOST 14918, 14918-80, 52246-04, R 52246), rolled sheet steel (GOST 1050-88), galvanized rolled steel polymer coating(GOST R 52146).

Profiles for the frame when leveling the wall

When conducting similar works Two main types of metal profiles are used: and rack-mount.

Guide profile for wall cladding

To level the bases, a guide metal profile is usually used, marked with the letters PNP or UD, which is also called the starting profile. Its purpose is to form the perimeter of the future wall structure, onto which the racks will be attached. Therefore, this type of profile is made of thick steel and has the following overall dimensions:

Standard length is 3,000 mm. At the request of clients, construction stores are ready to supply elements up to 6 meters long. However, if necessary, these parts are built up using the overlay method.
The height of the side wall (shelf) is 40 mm.
The width of the backrest can vary: guides with backrests of 50, 65, 75 and 100 mm are available.

To attach the guides to the wall, floor, or ceiling, holes with a diameter of 8 mm are pre-drilled in their back. If the pitch of the existing holes is not suitable, then it is not a problem to drill new ones using a conventional drill.

Rack profile for walls

The rack metal profile, designated PP or CD, forms the plane to which the drywall will be attached. It is easy to distinguish this type from the guides: its side walls are bent inward, forming the letter “C” in cross-section. This makes it more rigid and easy to attach hangers to. The element has longitudinal stiffeners that have additional function: it is convenient to center the screws in them.

To avoid confusion, we will list all the names of CD profiles. They are called ceiling profiles, rack, planar, racks.

Product dimensions:

Various lengths: from 2,500 mm to 6,000 mm. This makes it easy to choose required size, so how to splice such load-bearing elements undesirable.
The shelf height is standard and is 50 mm.
Width – 50, 65, 75 and 100 mm.

The rack profile is inserted into the guide, so it must match its width.

Profile for ceiling frame

For leveling ceilings or creating on them multi-level structures use the same UD and CD profiles. The only difference in the choice of products is their size. For the ceiling, elements with the following parameters are usually taken:

The guides are 3,000 mm long, 28 mm wide and with a side shelf height of 27 mm.

Ceiling-bearing metal profiles of the same length, with the same shelf height and width of 60 mm. The presence of additional stiffening ribs along the length allows you to create structures on the ceiling that can withstand heavy loads.

Profiles for forming partitions, niches and arches

Active use in the repair of structures built from plasterboard has led to the production of a wide range of parts for. The buyer can choose those that he requires for a particular case.

Guide partition profile

Guide metal profiles UW (PN) have different widths. This is explained by the fact that the thickness of the partition being erected can be different. Therefore, in the assortment of stores you can find UW profiles with a width of 50, 65, 75, 100 mm.

The length of such products is from 2 to 4.5 meters. The height of the side shelves is 40 mm.

Rack partition profile

Rack profiles for partitions CW (PS) have interesting feature: Drywall can be mounted on them on both sides. They often have notches for laying communications. In terms of dimensions, they are selected to match the guides used.

Reinforced metal profile

To strengthen doorways a reinforced version of the profile (UA) is used.

It is mounted in them as racks and has the following dimensions:

Length – 3,000, 4,000 and 6,000 mm.
The height of the side shelves is standard – 40 mm.
Back width – 50, 75 and 100 mm.

Increased strength is ensured by metal thickness reaching 2 mm. The back of the part is equipped with perforations and holes to facilitate installation.

Corner profile

Corner profile is designed to protect against accidental damage to corners plasterboard structures. As a rule, it is attached to putty, so it has perforations through which excess solution is squeezed out. Available in strips 3 meters long. The width of the corner sides is 25 or 31 mm.

Care should be taken when transporting these parts as they are easily deformed.

Arched profile

The arched profile differs from other types by the presence of cuts on the side shelves, which allows it to be bent, giving the desired radius of curvature.

Arched elements can be convex or concave. Their characteristics are slightly different:

Convex ones are available in lengths up to 6 meters and can provide a minimum bending radius of 1000 mm.
Concave – 3 meters long, minimum radius – 500 mm.

Often, craftsmen, when forming curved surfaces, do without using this type, replacing it with a guide. Cutouts in the form of petals are made in its side shelves at certain intervals, as in the photo. The smaller the bend radius, the more often the cuts are made.

How to choose the right profile

A reliable frame is the key to the structural strength of their drywall. Therefore, you should not skimp on the materials needed for its manufacture. It is better to choose profiles from a well-known company, even if the price of the products is higher. But in this case you won’t have to worry about the quality of the metal profile.

Qualities that a profile for gypsum boards must meet:

strength and rigidity - provided by thickness and correct processing material in manufacturing;
reliability - it is determined by the quality of the steel;
lightness - material that is too thick has a lot of weight and is inconvenient to work with.

When purchasing profiles, you should pay attention to their storage conditions. Despite the corrosion resistance of galvanized metal, products should be stored under a canopy. There should be no scratches or burrs on the profiles. It is good if the parts are supplied packaged.

Knauf metal profiles have only one drawback - their high price.

Gyproc-Ultra

Advantages of the Gyproc-Ultra profile:

cold hardening of steel using UltraSteel® technology;
harpoon effect: the self-tapping screw is easy to screw in, but difficult to remove;
holes closed with a tongue, which, when bent, prevents the part from bending when screwing in screws;
a corrugated surface with symmetrical recesses, allowing self-tapping screws to easily enter the metal and not slip off;

connecting elements using the tongue-and-groove method.

Note! There are many fakes and imitations of the Giprok-Ultra profile on the market. When purchasing, carefully examine the detail: the original has corrugation throughout its entire thickness, the indentations are clear and symmetrical.

In terms of price/quality ratio, Giprok outperforms Knauf.

Fasteners for mounting the frame

It will not be possible to assemble a frame without a variety of materials. Depending on the type of structure, the following elements can be used:

– for installation of load-bearing profiles on ceiling slab or a wall. They are fixed to the surface using dowels. The carriers are fixed in the hangers with self-tapping screws. There are a number of holes in the side wings of this fastener for adjustment. After fixing, the protruding parts are simply bent at an angle of 90˚ so as not to interfere with the installation of drywall.
Anchor hangers – for mounting the ceiling frame. They have a rod, adjusting the length of which, you can set the required distance between the frame and the ceiling.
Extensions – for connecting profiles. This need arises quite often, and using an extension cord allows you to get a stronger and more rigid connection.

Covering external and internal surfaces with various sheet materials is a fairly popular finishing method. Metal profiles of various configurations are used to create durable frame, on which slabs, sheets or panels are attached. By creating flat and volumetric structures Using metal profiles, walls, fences, roofs and ceilings are constructed.

Advantages of a metal profile

Although you can use wooden beam, plastic or profile pipe, specialists in repair and construction work prefer metal profiles.

This is due to the fact that the metal profile has the following positive properties:

Immunity to changes in temperature and humidity. The metal does not change its size and configuration under the influence of these factors.
High strength and reliability. The various profiles are thick enough to withstand pressure or tensile forces. The presence of stiffening ribs only enhances the reliability of the products.
Corrosion resistance. As a rule, iron products are coated with zinc or polymer coating. This allows them not to rust even in a humid environment. Aluminum baguettes do not require additional finishing.
Ecological cleanliness. Metal profiles do not stand out in environment harmful substances even under the influence high temperatures caused by an open flame.
Easy to process. In order to cut or bend a profile, ordinary household tools, which are in every home: drills, hacksaws, grinders or metal scissors.
Durability. High-quality products have a service life of decades.
Affordable price. Metal profile is inexpensive building material, the cost of which has an insignificant share in the total estimate of repair and construction work.

Quite a lot of components have been created for metal profiles, with which you can create structures of any size and complexity.

Using steel and aluminum baguettes, you can install siding, stretched PVC fabric, plasterboard, plastic, MDF and others finishing materials.

High specifications metal profiles allow you to use it without restrictions, in almost any conditions.

Profile for drywall and siding

Drywall is one of the most popular finishing materials that can be used to cover both walls and ceilings. Certain brands of gypsum plasterboard are used for finishing fireplaces, showers and kitchens.

For this purpose, the following types of profiles are used:

Guide. These products serve as the basis for attaching rack or ceiling profiles. The parts have a U-shaped section. The length of one section is 300 cm or 400 cm.
Ceiling. These products are intended to create lathing onto which finishing material is screwed. Having a cross-section of 60x27 mm, they fit perfectly into the opening of the guide profile.
Rack-mounted. The frame for walls and partitions is assembled from elements of this type. These products are fixed in guides that are attached to the floor, ceiling and walls.
Angular. Such parts serve to strengthen the corners at the joints of plasterboard sheets after it is fixed to the frame.
Mayachkovy. These products are used for leveling concrete and brick walls plaster mortar.

It is impossible to make a frame from steel baguettes without the components used to attach the profiles to the wall and to each other.

Assembled steel frame The following parts are used:

cross connectors;
longitudinal connectors;
corner connectors.

The individual parts are connected to each other using self-tapping screws. This ensures a strong and secure fit.

Baguettes for suspended ceilings

Stretch ceilings are the most presentable and practical option for finishing residential, utility and commercial premises. Baguettes for stretch fabrics made of aluminum. This metal is strong enough to withstand the intense pressure exerted by the taut polyvinyl chloride film.

According to the method of fastening baguettes for stretch ceiling are divided into the following categories:

Wall. These products are the most popular. The canvas is fixed at a distance of 5 cm or more from the floor slab.
Ceiling. These baguettes are fixed to load-bearing plate in cases where the wall material is not strong enough to withstand the tension of the canvas. The use of such profiles allows you to fix the film at a distance of 4-5 cm from the main ceiling.
Universal. These baguettes can be mounted both on the ceiling and on the walls.
Structural. These are complex products that are used to create steps, protrusions and recesses in multi-level stretch ceilings.
Connecting. Profiles of this type are used to connect several canvases when finishing large areas.

If it is necessary to create a curved structure, triangular cuts are made in the profiles.

Profiles for polycarbonate

Cellular polycarbonate is used for finishing canopies, gazebos, office and residential premises.

To create polycarbonate structures, aluminum profiles are used, such as:

Connective. Used for hermetically sealed vertical joining of sheets.
Skate. Designed for connecting polycarbonate panels on a gable roof.
Wall-mounted. It is used in cases where a polymer plastic roof is adjacent to a permanent structure.
Tortsevoy. This profile covers the lower edges of the polycarbonate sheets, protecting them from damage and giving the structure a finished look.

Since the aluminum surface is visible, it can have different textures and colors created using a polymer coating.

Drywall is one of the most popular finishing materials. It allows you to quickly and efficiently level walls, create a multi-level ceiling, interior partitions, etc. Installation plasterboard sheets produced on a frame assembled from special metal profiles. The quality of the entire structure depends on how correctly the material and components are selected. Drywall can be installed without a frame. In this case, the sheets are fastened using special glue. Most often this is done:

if the base surface does not require leveling;
when low weight of the structure is important.

To produce a profile for plasterboard, sheet steel with a thickness of 0.25-0.6 mm is used. Her upper layer coated with zinc. This protection increases corrosion resistance and makes products more durable. Manufacturers offer several types of profiles that allow you to create frames for plasterboard structures of any complexity. Elements are selected according to their function and location.

Features of manufacturing profiles for plasterboard

The main material used is strip - galvanized rolled steel strip up to 0.6 mm thick. This metal strip is fed to a rolling machine, where it is given the required cross-section shape. The resulting profile is cut into pieces of the required length. The size adjustment is made once, before starting work, then the process is carried out automatically. The following equipment is used in production:

bending machine. Forms the required profile section;
guillotine. Cuts the resulting workpiece into pieces;
automatic system control. Checks the dimensions of the received workpieces.

Main normative document regulating the characteristics and dimensions of profiles is GOST 11474-76. Many domestic enterprises manufacture these products in accordance with TU 1122-001-70890834-2009. All profiles for plasterboard sheathing are divided into six main categories. Four of them are main, intended for assembling the structure, and two are auxiliary.

Types and designation of profiles for drywall

Guides for frame assembly. Such profiles are designated UW or PN (depending on the manufacturer - domestic or foreign). Standard depth is 40 mm. The width can be different and is selected in accordance with the design. The main purpose of this profile for drywall is to serve as a guide for attaching subsequent elements, such as racks. It is used in the assembly of wall frames and partitions.
Ceiling guides. They are marked with the designations PPN, PNP or UD. Profiles in this category have the same functions as the previous ones. They are mounted around the perimeter of the ceiling and serve as guides for other frame elements. Such drywall profiles are often used to create multi-level structures. The depth of the ceiling guide is usually 27 mm.
Rack profiles. They are intended for vertical installation, for example, when creating partitions from plasterboard or when covering walls. The elements are attached to the guide profile. Depending on the manufacturer, they are labeled as PS or CW. The rack element must withstand compression loads, therefore it is additionally reinforced with stiffeners.
Ceiling profiles. They are designated CD or PP. The profiles are attached to the ceiling using a direct suspension or using an anchor clamp. Depth - 27 mm, width can be different. Such elements make up the main frame suspended ceiling from plasterboard.

In addition to the listed products, corner and arched profiles are also used when working with drywall. The first ones are installed at the junction of the walls. They are designed to align corners and give them precise geometric shapes. The corner profile can be either solid or perforated. The second option provides better adhesion to the finishing material. The arched profile is designed for creating curved structures from plasterboard. It is used in the design multi-level ceilings complex shapes, for making niches, internal partitions, door and window openings non-standard shape. The arched profile is available with both concave and convex surfaces.

If plastering of the wall is required before installing the frame, special beacons are used. This element is not a profile for drywall. Its task is to ensure even application of the working solution. The beacons are fixed vertically in increments of 20-30 cm, checking the direction using a plumb line. Their use helps to obtain a flat surface with a level difference of no more than 5 mm.

In addition to the listed profiles for drywall, when creating the frame, auxiliary components are used, for example, specialized fasteners. It is easy to use and can significantly reduce installation time.

Types of fasteners for plasterboard structures

Two-level connectorWITHD. Designed for fastening corresponding profiles perpendicular to each other. The connection is made with special self-tapping screws. Products are located at different heights.
Single level connectorCD. It secures profiles located at the same height at right angles. The second name for such a connector is “crab”. If the load on the structure is light (up to 20 kg/m2), self-tapping screws are not needed; just snap the profiles into place.
Direct suspensionCD. The main scope of application of the product is installation plasterboard ceilings. This suspension can withstand a load of up to 40 kg. The element is installed on the ceiling surface. Before joining the profile, it is bent in the shape of the letter P, after which it is secured with self-tapping screws.
Anchor suspension (with traction). It attaches the CD profile to the ceiling surface. The element is used when the length of the direct suspension is not enough. The maximum load is 25 kg. The fasteners are inserted into the profile, and the rod is threaded through special holes in the spring.
Longitudinal connector. Used to extend the CD profile for drywall. The longitudinal connector is inserted with end side, after which it is secured with self-tapping screws.
