What does a profile for drywall look like. Profile for drywall, its types and dimensions. Aluminum profile and its features

In modern times, a large number of opportunities to make the room beautiful and cozy with a minimum amount of costs. One option is to use drywall sheets, which will be discussed in more detail in this article.

Peculiarities

Profiles are a very important element in creating any interior. In order for the structure to withstand the GKL, the profile is made of steel or aluminum. Steel options are more popular, due to the fact that these are economy class models. Aluminum have more good performance, but their price is not suitable for everyone.

There are two options for steel profiles - regular and with a protective layer. Ordinary profiles are not very durable, but they are cheaper. It is good to use such profiles for not very heavy structures, as well as in rooms where there is not too much humidity.

For rooms in which the humidity is higher, it is better to install galvanized or aluminum metal profiles.

Types of metal profiles

In any hardware store you can find a large number of different profiles. In order to choose the right one, you need to understand how they differ from each other. There are the following types of structures:

guide

The abbreviated designation of this profile is PN (guide profile), it is also called the starting one. It has a U-shaped section. The walls of this profile are smooth. Most often, this product is used to support various jumpers and racks, it is placed inside the structure, and the rest of the parts are put on it in the future. Dimensions: 28-27.50-40.60-27.75-50.100-40 mm.

rack

It is usually abbreviated PS. This profile is inserted inside the guides, the remaining parts are attached to these structures. The profile carries a large load, because of this it must be more rigid. He also has a U-shaped structure, it has additional shelves to strengthen the structure. Dimensions: 50-50.65-50.75-50.100-50 millimeters.

It is necessary to pay attention to one important fact. If the walls in the building have a fairly flat surface, then it is better to fix the rack-type profile directly to the wall surface.

If the walls are not very smooth and have a strong slope in a straight line, then the profile should be installed on U-type mounts.

Ceiling

The main designations of this model are PP and PPN (bearing and guiding ceiling profile). This profile also has a p-shaped cut, but its cut is much smaller than that of the wall profile. Inside this profile there are small shelves and additional ribs to make the frame of the structure more rigid. This profile also has a lower height, which saves space in the room. In addition, it is worth noting that the drywall used for the ceiling has a smaller thickness, which reduces the load on the profile.

It is worth noting that the transverse rails should be fastened so that the distance between the fasteners is no more than 900 millimeters.

In order to do this, you need to use spring mounts and U-shaped brackets. To more firmly connect the jumpers, you can use crab clips.

In rooms where chandeliers and other heavy structures are located, the frame should be made with additional transverse beams. This will protect the entire structure from collapse. The size of the ceiling models: 60x27.75x50 millimeters.

Arched

The profile has a more complex structure, it has cuts on the sides, which increase the flexibility of the design. This aspect is an important plus for creating a flexible structure.

There are also a number of additional profiles. They are most commonly used for suspended ceiling construction and other decorative work.

To make the structure stronger in places of special bending, you can use a corner made of metal or plastic. This is necessary so that the structure can be bent at any angle. Corner whips can be from 2000 to 3000 millimeters. The width of each shelf can be of several types: 20,25,30 mm. The smallest bending radius of the structure must be at least 500mm.

It is worth noting that the whips themselves are quite an expensive thing, and in order not to overpay 1000 rubles for each pipe, you can create it yourself.

To do this, it is worth making many large cuts on the side ribs at a distance of 40-100 mm from each other.

• The corner metal profile in the section forms a right angle, in which the central part protrudes slightly. The profile is usually used to decorate various plasterboard structures. Most often it is used to design corners in a structure. There are several types of them:
• Two shelves with large and perforated holes, which are needed in order for the corner to look good aesthetically and become part of the plaster. The rest of the structure rests on this corner.

• There is a corner profile for drywall with mesh inside. In order for adhesion to be better, a mesh can be glued inside the structure, on which the rest of the parts will be held.
• Corner profile on a paper basis. Two strips made of metal are glued onto thick paper. It is usually used in structures that receive the maximum load, for example, in window openings, various niches.
• The beacon profile is used as a base for plastering, the main purpose of this device is to level the surface. This profile looks like a metal bracket. The width and height of this profile is small, the widest is 1-3 cm.

Additional elements

Another important element used in the design for leveling the surface with drywall is a suspension.

It also comes in several types.

• The perforated hanger looks like a 125-60mm metal band. The suspension is divided into three parts. The central part allows you to attach the product to the ceiling, the side ones are used to hold the rest of the structure. A 90 degree bend is also made.
• Anchor hangers are most often used to install suspended ceilings. The main advantage of this suspension is the height adjustment, which is very necessary for installation. false ceiling.

• The connector is single-level and two-level. This is a connector that is used to fasten profiles that cross. It is also needed in order to make a false ceiling.
• Profile extension - a device that is used if the length of the profile is not enough. It looks like a bracket measuring 110-58 millimeters.

How to choose

In order to choose the right design, it is very important to pay attention to what the profile is made of. For drywall, galvanized profiles should be used. This is the most durable material. In order to distinguish quality profile need to focus on different aspects.

To collect good profile, it is worth observing some nuances.

• It should be galvanized, zinc should be almost one hundred percent. In this case, the frame will almost never be subject to corrosion.
• Metal profiles, especially models for walls, must be very durable. The wall profile bears the main load, and the profile must also align the wall well and not corrode.
• The ceiling profile must be thick, otherwise the structure will take up too much space. The size of the product is 0.4-0.6 millimeters.

In the process of buying and operating, be sure to take the advice of professionals in the field of repair.

• It must be remembered that walls and ceilings are never perfectly even after roughing. In order to level the wall, you can use drywall sheets, which should be at a certain distance from the wall. This will allow you to quickly level the wall without much loss of space in the room.
• There will always be a small space between the insulation and drywall sheets. This is necessary so that moisture does not collect between the wall and the structure. A so-called air cushion is formed between the sheets and the wall.

• There should be a gap between the wall and drywall. This space is very important during construction, it allows you to fit insulation into this place.
• The frame is a necessary moment in the construction of arched structures, it is he who allows you to make the structure more flexible.
• Drywall sheets do not have a high strength threshold. If you need to fix some heavy structures, you should use profile frame, without it, the structure will simply break. Fasteners must necessarily be in contact with the main frame.

Auxiliary profiles

It is also worth remembering that there are auxiliary profiles. They are used during finishing works together with drywall and there are several varieties.

• Reinforced thick profile well suited for rooms that have a heavy partition between the doors. It is also well suited to increase structural rigidity. Most often they have a fixed length - 3000-4000mm, but if you wish, you can buy a product with a length of 6000mm. The height of the ribs is standard - 40mm, the wall thickness differs from conventional profiles and is 2mm.
• Protective metal corner. It serves to protect the corners from damage during operation. After the installation work the corner is puttied, and it is also covered with finishing paint. In order for the paint and mortar to better penetrate inside, a large number of small holes are used. The length of such corners is the same - 3000mm.

There is another version of the protective corner, which is not placed under putty, but is covered with plaster. In order for it to penetrate better, a special mesh is used.

Fasteners and various connecting elements

During the manufacture of the frame, it is very important to correctly connect the structure. Sometimes this can be done quite simply by inserting profiles into each other, but this is not always possible. In such a situation, it is worth using fasteners of various types:

1. Double layer connectors. This design is needed in order to connect two parts, at an angle of 90 degrees in a different plane. Most often, these parts are made of galvanized steel in the form of a flat reamer. Before starting installation work, this thing will need to be bent manually at the right angle, the width of such a connection is 60mm. In order to fix the structure, self-tapping screws must be screwed into the side parts.
2. Single-level connectors or "crabs". These fastening systems are used to connect two identical models at an angle of 90 degrees. They can be found in almost any store ready-made. Installing this part will not be any problem, it simply snaps into place with reverse side designs.

If the load on the frame does not exceed 20 kg per square meter, then a conventional latch is enough to fix the structure. If the load is greater, then self-tapping screws should be used to strengthen the fixation.

Direct hangers

applied during installation. various designs, which are used for ceiling and attaching vertical type profiles to the wall. These products can be found in any store. They are made in the form of flat plates, and in order to install them, you will have to bend them manually in the form of the letter P.

If you want to mount various plasterboard structures with your own hands (suspended ceilings, arches, partitions, niches, etc.), you first need to learn how to understand the profiles that are used to create a drywall frame.

The choice of this material should be made correctly and reasonably, so that the erected structure exactly matches the loads imposed on it.

In the modern construction market, the drywall profile can be the most diverse. Here the choice must be made on the basis of the requirements of the structure to be mounted. Since for a partition, ceiling or arch, completely different profiles are needed.
Drywall profiles differ in the following parameters:

• purpose;
• appearance;
• dimensions (thickness).

Choosing the right profile requires taking into account all these parameters. Only then will you do everything right and buy only the necessary frame elements.
Also, profiles for forming a frame for a drywall construction are of the following types:

• guide for application on the ceiling PNP / UD;
• ceiling profile PP/CD;
• rack profile PS/CW;
• guide profile PN/UW.
• corner profile. It is used when creating an arch or curly partition.
• beacon profile. It is used for leveling the surface in order to create a flat wall.

different profiles

The first four types are basic, and the rest are auxiliary.
As you can see, the choice is quite large. Therefore, before you go to the store for a purchase, you need to clearly know which profile you will need in each specific situation.
You need to choose only those types of frame elements that you definitely need. So you save money and greatly simplify your task of installing a partition, arch or any other structure.

Explanation of abbreviations

For a person who decided to make only partitions or other drywall structures, profile abbreviations do not say anything, unlike construction professionals. Choosing the right profile without the help of sellers is possible only if you understand the meanings of these symbols. Consider the most common of them:

CB-50

• PP60 or CD-60 is a ceiling profile. The most popular type of frame element. It is the basis of any ceiling crate. It is also used in the construction of various built-in structures and partitions. Curves and shapes can be formed from it, so it is considered an excellent replacement for the arched profile, which is much more expensive. Considered universal;
• PN27 or UD-27 - ceiling guide profile. Also widely used in construction. Has excellent bending properties;
• CW-50 is a rack-mounted main element. Used for mounting light structures. It can also be used to assemble partitions. In practice, it is rarely used, as it requires a frequent step when fastening;
• CW-75 and CW-100 - essentially resemble the CW-50. Better quality CW-100. Used much more often than the previous version. As a rule, partitions are built from it;
• UW-50 - is a guide element used for CW-75 and CW-100. Used to align rack profiles in the same plane. It is the basis for the frame when sheathing walls with plasterboard sheets.

Profile

Knowing the interpretation of these abbreviations, you will know exactly what type of profile is needed in each specific situation when working with drywall.

Wireframe Options

The above information is very important. But here there is another equally important "pitfall" on which you can not only stumble, but also drown. And this "stone" is the thickness of the frame element.
Note! Buy a metal profile only of the required thickness. This parameter is determined by the required strength and rigidity of the structure. For purely decorative designs, not very thick elements can be used. But massive structures, such as a wardrobe, partitions with many niches require the use of elements with a greater thickness.
Modern metal profiles in thickness are of three main types:

• thickness 0.4 mm. It is considered the most “weak”, therefore it is not used when assembling large-scale and large-sized drywall structures. When fastening such elements, the screws in them very often simply scroll;
• thickness 0.45 mm. It is considered the "golden mean". It can already be used for lathing walls, ceilings and further installation of drywall on it;
• thickness from 0.55 mm. The most expensive and "serious" profile. It is used to install complex wall devices, as well as to assemble a structure on which a large load is expected.

The thickness of the metal profile should be chosen based on what you plan to do from drywall: arches, partitions, niches, ceiling structures, or simply sheathe the walls.

Installation of frame elements

direct suspension

It is not enough just to choose the material. It still needs to be installed correctly. For the installation of metal profiles, there are several options for mounting systems.
The list of fastening systems in this case includes:

Note! Instead of this extension, you can use the UD-27. For joining parts, dimensions of 20 cm or more are used.

• single-level crab connector. Connects frame elements at an angle of 90 degrees. It is considered a fastening system for ceiling structures. The elements are fixed with self-tapping screws. May also have been replaced by UD-27;
• two-level connector. With its help, they form T-shaped joints at the point of approach to the wall;
• suspension with clamp and traction. It is used in the formation of raster ceilings. Its use leads to a significant underestimation of the ceiling level. In this case, understatement can take a whole meter! But one such suspension can account for up to 25 kg of weight.

Understanding where and what type of fastening you need to use, you can easily choose not only a fastening system, but also a metal profile to create any complexity of plasterboard structures.

Device design

From drywall, when using various types frame elements and fastening systems, you can easily assemble any device. Most often, walls are leveled from drywall, ceiling structures are installed, and partitions are also assembled.
Consider what we need when forming the frame for the partition.
A similar design can be constructed using the following elements:

• profile guides. They will act as load-bearing elements;
• rack profiles. They are used to enhance the strength and rigidity of the structure under construction. In addition, niches or shelves are formed from them.

Such elements are needed if the design is simple and does not contain complex curly components. Very often, with the help of partitions, space is delimited into certain zones. They are often performed as decorative elements interior. To create them, it is necessary to use arched flexible metal profiles that can form the desired shape.
As you can see, a wide variety of markets building materials can bring confusion when buying frame elements for further sheathing with plasterboard sheets. Therefore, before going to the store, be sure to decide what you need. This will save you a lot of time, money and make your installation work easier.

Types of profiles for drywall and their purpose: the main classification

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

Surface-planar profile for drywall

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

Drywall guide profile: distinguishing features

PN (UW) is marked. It 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 rest of the structural elements are put on it.

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

Rack profile for drywall: design features

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

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

Drywall ceiling profile: main types

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

To fix elements, you can use a special . Allows you to install a ceiling structure 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 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 in forming the perimeter of the partition and providing the required configuration.

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

We offer you to see photosthat you can create:

Arched drywall 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 a radial bend. It is made most often from PP 60/27. The standard profile length for drywall is 3 m. The minimum bending radius of the concave element is 500 mm.

Auxiliary components of the profile frame for drywall

For system installation right size and shapes may require special drywall components, 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 a restriction around the perimeter of the cladding. The outer side is puttied;
• hat for mounting sheet . Attaches to the base. Allows you to opt out of guides;
• l-shaped, if it is necessary to install a finishing or starting bar in a wall with open ends;
• z-shaped to increase the rigidity of the system;
• beacon, if the base is to be leveled.

Fasteners

To fix the profile, dowels are used either. They are hammered or twisted at the intersection of adjacent elements. Fasteners 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 cruciform configuration. With their help, it is possible to provide a rigid connection of intersecting strips;

• 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 from drywall

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

Profile coating and material thickness

When buying, 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 more rigid the metal profile will be and the higher its cost. If the element is not thick enough during installation and under operational load, it can change its geometry.

Drywall is one of the most popular finishing materials, used not only to add decorativeness to walls and ceilings, but also to create additional interior partitions.

The installation of such sheet elements is quite simple, as it is carried out using special profiles for drywall various kinds and sizes.

Let's figure out how to choose the right fastener for each specific situation.

Types and application of drywall profiles

Elements for fixing drywall sheets are made by cold rolling a long tape, the thickness of which is in the range of 0.55 - 0.8 mm.

One of most well-known manufacturers is Knauf, which creates rolling profiles for buildings of various purposes. The manufacturing process is carried out in strict accordance with the regulatory document TU 111-004-04001508-95.

Depending on the places of application profiles for drywall sheets are divided into:

• Ceiling;
• Wall.

Also exists classification of metal profiles by purpose:

• For decoration existing wall and ceiling structures;
• For creating new barriers in room.

Like any other frame structure, metal crate for fastening consists of many different elements. They differ from each other in thickness, bending shape and degree of bearing capacity. Let's take a closer look at each type.

Guides with UD or PN marking

Based on UD details the entire subsequent frame is created, formed by attaching other elements to them.

It has a significant bearing capacity, which makes it possible to maintain the entire system in the initially specified geometric state, preventing the development of bending deformations inside the crate.

Often such parts have a perforated structure, which makes it much easier to attach them to sheathed structures.

Dimensional values:

• Channel height - 27 mm;
• Profile width - 28 mm;
• Standard length and weight - 2.5 m (1.1 kg), 3 m (1.2 kg), 4 m (1.6 kg), 4.5 m. (1.8kg).

Guide parts with UW or PN marking

Applies for wall structures, as well as the basis for the construction of partitions. According to the principle of operation, they are similar to the UD profile, but they have slightly different geometric characteristics:

• Channel height - 40 mm;
• Profile width:

1. 50 mm;
2. 75 mm;
3. 100 mm.

• The thickness of the metal part is 0.5-0.6 mm;
• Standard length and weight:

1. 2.75m (1.68kg), 3m (1.83kg), 4m (2.44kg), 4.5m (2.75kg);
2. 2.75m (2.34kg), 3m (2.55kg) and 4m (3.4kg), 4.5m (3.83kg).

Rack profile CW or PS

Rigid element of the crate serving to reinforce the whole structure. Installation of racks is carried out by fixing in guide profiles with a step of 400 mm.

Dimensional characteristics:

• Height - 50 mm;
• Profile width:

1. 48.8 mm;
2. 73.8 mm;
3. 98.8mm.

• The thickness of the metal part is 0.5-0.6 mm;
• Standard length and weight:

1. 2.75m (2.01kg), 3m (2.19kg) and 4m (2.92kg), 4.5m (3.29kg);
2. 2.75m (2.34kg), 3m (2.55kg) and 4m (3.4kg), 4.5m (3.83kg);
3. 2.75m (2.67kg), 3m (2.91kg) and 4m (3.88kg), 4.5m (4.37kg).

Carrier CD or PP

As the name implies, this type of frame part takes on the load from the entire structure cladding or partitions. In addition to CD (according to KNAUF), there is a PP marking, which most fully reveals the purpose of such profiles.

PP marking stands for "Ceiling profile", that is, these elements can be used not only for wall structures, but also for the ceiling.

Dimensional characteristics:

• Height - 27 mm;
• Profile width - 60 mm;
• The thickness of the metal part is 0.5-0.6 mm;
• Standard length and weight - 2.5 m (1.65 kg), 3 m (1.8 kg), 4 m (2.4 kg), 4.5 m. (2.7kg).

arched profile

Designed to create curves and arched elements. It is a kind of CD and UD profile. The main distinguishing feature - significant perforation, as well as the presence of multiple side cuts, allowing you to freely bend this metal profile.

Geometric characteristics convex elements:

• Length - 2.6m, 3.1m, 4m.
• Radius of curvature:

1. 0.5-1 m;
2. 1-2 m;
3. 2-3 m;
4. 3-4 m;
5. 4-5 m;
6. >5 m

For concave elements:

• Length - 2.6m, 3.1m, 4m.
• Radius of curvature:

1. 1-2 m;
2. 2-3 m;
3. 3-4 m;
4. 4-5 m;
5. >5 m

It is applied for ensure best quality finishing works.

Allows more even plastering of the entire surface.

Dimensional characteristics:

• Cross section:

1. 22*6mm;
2. 23*10mm;
3. 62*6.6mm.

• Profile length - 3 m.

Additional elements

For the implementation of drywall sheets also you will need the following items:

• anchor hanger attaching PP profiles to the ceiling. Equipped with a pull and a clamp, with the help of which the gap between the main structure and the drywall sheet is adjusted;
• direct suspension, with the help of which profiles with PS and PP marking are fastened to wall and ceiling elements;
• Screws and dowels, with which the elements are attached to the walls and ceiling;
• Connector "Crab", which serves to create integrity between the cross parts;
• Extension required for joining adjacent lanes;
• Connector, which helps to fasten 2 levels of PP profiles.

For the installation of partitions, profiles with the letter W at the end of the marking are used. Metal elements with the letter D are used for the construction of wall frames.

Parts manufacturing materials

Details for creating a frame for drywall made of galvanized steel because it has excellent anti-corrosion properties.

Even if the integrity of the zinc coating is damaged, the duo of steel and zinc will create an oxide film that prevents rust on the profile elements.

Also galvanized is excellent resists moisture, sudden changes in temperature, and is also an absolutely safe material for humans.

Dimensions of the crate for drywall

Consider the calculations of the geometric dimensions of the crate using the example of finishing the ceiling.

For the installation of a plasterboard ceiling structure you need to purchase 2 types of metal profile:

• With PP marking;
• With PN marking.

Since the PN profiles are guides, their total length should be equal to the perimeter of the room.

Amount is determined by the formula:

N=P/x; where N is the required number of elements (pieces); P is the perimeter of the room, equal to the sum all its sides; x is the length of one element (the most common are 3 and 4 meter profiles).

To determine the number of parts of the software, you need to decide how they will be installed.

Regular styling

It is characterized by the initial installation of guide elements around the entire perimeter of the room, and then the laying of PP profiles in increments of 0.6 m (since the width of a standard drywall sheet is 1.2 m, and the PP profile should be located strictly in the middle of it).

Calculation formula for the required footage of PP profiles:

L1=N*B, where L1 is the required amount running meters PP elements, N - the number of middle elements, determined taking into account the step of the structures, B - the length of the room.

It should also be borne in mind that in order to ensure normal stiffness characteristics plasterboard ceiling you will need to install transverse parts, the pitch of which should be 0.5 or 0.6 m.

The calculation of the footage is carried out according to the formula:

L2=N*A, where L2 is the required transverse PP profiles, N is the number of diameters determined by their pitch, A is the width of the room.

The desired number of piece PP elements is found by the formula:

L=(L1+L2)/x, where x is the length of one element (most often 3 or 4 meters).

Complex styling

The calculation of the number of elements is similar to the normal installation option. However, here it must be taken into account that with complicated installation profiles should be under each of the edges of the drywall sheet.

Also more frequent step of secondary elements will be required(0.3 or 0.4 m). The result is a more powerful crate that can withstand significant loads.

For a wall and a partition, the calculation is carried out in a similar way, only instead of the perimeter of the room, you need to use the perimeter vertical wall premises.

Also, when constructing a pier, the resulting number of elements must be multiplied by 2, since it will be produced double-sided installation of drywall sheets.

How to choose profiles for wall construction?

Successful selection of profile elements depends on 3 components:

• The right choice of the purpose of the parts (for a wall, ceiling, partition or arched structure);
• Competently carried out calculation of the required number of elements;
• Parts manufacturer.

How to implement right choice we have already dealt with the first two points, it remains to decide on reliable company that manufactures profiles for fastening plasterboard sheets.

Given the reputation in the building materials market, 2 of the most reliable companies can be distinguished:

• Knauf;
• Gyprok.

These German firms have gained their high position thanks to the consistently excellent quality of materials, as well as the strict implementation of all regulatory requirements storage and production of materials and products.

In addition to the products of these manufacturers, there are economy analogues, produced in the post-Soviet space.

These include:

• Remax;
• Albes;
• Buddetal;
• Special profile;
• Interprofil;
• Kievmetalloprom;
• NeiCO Manufacturing Ukraine;
• SMC "Stilline" and others.

They not inferior in quality imported frame profile elements, however, they have a more affordable price.

The construction of a drywall or even a partition element requires certain knowledge and skills in this area.

But if you choose the right quality components of the frame, as well as make correct calculations of the number of elements, you can easily build a plasterboard structure with your own hands.

The popularity that drywall has gained in last years, due not only to its high performance.

Simple installation, which is based on a light and reliable metal profile - that's what attracts buyers who decide to start renovating the premises.

The unification of profile structures is the main factor that made working with drywall accessible not only to professionals, but to home craftsmen. The types of drywall profiles offered on the market are few. This makes it easy to understand the purpose of each element before starting work.

Three types of profiles are based on plasterboard structures of various shapes and sizes:

• planar;
• Wall;
• Arched.

The first type is used for sheathing individual planes (walls, ceilings). The wall profile has increased rigidity. It is used as a supporting frame for interior partitions sheathed with gypsum boards. The purpose of the arched profile is clear from its name.

Profiles for ceiling and wall cladding

Considering, it is necessary to dwell in more detail on the structural elements, without which its installation is impossible.

When creating wall and ceiling structures, two types of galvanized steel profiles are used - UD and CD. You will not be able to build a curved surface without an arched profile. All listed profile elements have standard sizes cross section. The differences between them are only in the length and thickness of the metal used.

UD - guide profile for drywall. It is designed to create an mounting plane and is placed along the contour of the future false ceiling or wall cladding. The carrier profile CD is inserted into it. It forms the frame of the crate to which drywall is attached.

The width of the UD profile is 28mm and the height is 27mm. The length is presented in two versions: 3 and 4 meters. The wall thickness depends on the manufacturer and can be between 0.4 and 0.6 mm.

When deciding which profile is needed for drywall, first of all pay attention to the thickness of the metal. Elements made of thin steel (0.4 mm) can only be used for wall cladding. Thick metal (0.5-0.6 mm) will securely hold the suspended ceiling system.

CD - bearing planar profile. It is used to form the frame and takes on the bulk of the load. This structural element is responsible for the spatial rigidity of the frame and serves as the basis for fixing drywall.

CD profile width - 60 mm, height 27 mm. The standard length is offered by manufacturers in two sizes: 3000 and 4000 mm.

A flat profile is good for everyone, except for one point: it is impossible to create a basis for lining an arched opening or a curved surface from it. The manufacturers solved this problem very simply: they took a standard CD carrier profile and made figured cuts and holes in it. This is how an arched profile turned out, the dimensions of which completely coincide with the width and height of the carrier.

Mounting dimensions of the profile for arched drywall: width 62 mm, height 27 mm with a length of 3 or 4 meters. You can bend this profile not only inward, but also outward. In this case, the bending radius should not be less than 50 cm.

Some companies, such as Knauf, offer a ready-made curved convex or concave arched profile designed for domed structures and curved ceilings. This is a regular CD profile molded on the factory equipment.

Partition profiles

They are marked with symbols UW (guide), CW (carrier or rack). Compared to planar profiles, these elements have a greater width and height.

Their main size range is as follows:

• Carrier CW -50/50mm, 75/50mm, 100/50mm, 125/50mm, 150/50mm;
• Guide UW - 50/40 mm, 75/40 mm, 100/40 mm, 125/40 mm, 150/40.

Variations in the length of the supporting rack profile 2.6 - 4.0 meters. The standard guide length is 4000 mm. In terms of cross-sectional shape, partition profiles differ markedly from planar profiles. Two longitudinal ribs are rolled back on them, which increase the rigidity of the wall, and an H-shaped cutout is made in the rack to pass cable lines.

UW drywall guide profiles are used to set the mounting plane of the wall and install the supporting profiles. They are mounted around the entire perimeter of the partition (on the walls, on the floor and ceiling).

The rack profile CW is used to form the frame. It is most often installed in increments of 40 cm so that the seams of the drywall sheets fall on its surface.

Another area of ​​application for reinforced CW and UW profiles is where the highest possible spatial rigidity is required from the frame. Here, their functions remain the same: creating a guide plane (UW) and a carrier batten (CW).

Briefly about the installation of profiles

As we have already said, the guide profile for drywall serves as a "baseline" that determines the plane of the sheathed surface. It is attached to the walls and ceiling with dowels and screws.

To assemble the assembly from the guide and carrier profiles, two methods are used:

• Self-tapping screws ("fleas");
• Mechanical cutter.

The latter method of interconnecting profiles speeds up the assembly process, eliminating manipulations with a screwdriver. However, it has one drawback: it is quite difficult to disassemble such a connection (an analogue of a riveted one) if necessary.

For fastening the carrier profile to a wall or ceiling, straight plate or pin (sliding) hangers are used.

To connect the supporting profiles in the perpendicular direction, single-level or two-level "crabs" are used - rectangular stamped plates.

Estimated prices

Prices for a metal profile for drywall installation vary significantly depending on the size and thickness of the metal. We will consider market offers according to standard characteristics.

Guide profile UD (length 3 meters, metal thickness 0.5 mm) can be purchased for 60-90 rubles. The carrier profile CD of the same length and thickness is sold for 80-130 rubles.

The average prices for a UW (PN) wall guide profile 3 meters long look like this:

• 50x40x0.4 mm - from 60 to 70 rubles;
• 75x40x0.4 mm - 80-90 rubles;
• 100x40x04 mm - 90-110 rubles;

A profile with a thickness of 0.6 mm is more expensive on average by 25-30%.

Estimated cost of rack CW (SP) profile (3 meters):

• 50x50x0.4 mm - 80-90 rubles;
• 75x50x0.4 mm - 100-110 rubles;
• 100x50x0.4 mm - 120-130 rubles.
