Configuration interior spaces in many buildings it is such that it is impossible to do without the formation of external corners. For example, only one doorway, connecting two rooms, creates external corners on both sides, and there can be quite a lot of them, especially in office premises. One of the main disadvantages of such corners is that when finishing them modern materials(tiles, drywall, etc.) a joint is always formed. It not only spoils the overall appearance, but is also quite vulnerable to damage. To protect such joints to the maximum, a metal profile is used - an outer corner.
It is important not to confuse these products and external corner from a profile for plasterboard. Since the external corner profile is a product designed to protect the ends tiled surfaces, and at the same time it performs a decorative function. In fact, it is an additional element that will be part of the decor. A outside corner from a profile for plasterboard - this is just a corner made of a metal profile for general construction purposes, two sheets are secured with it of this material at the corner joint. After the corner is completely finished, it will not be visible, since it will be hidden under a layer of primer and external finishing material.
The direction of the ArtProfil company is production and wholesale trade products made from metal profiles for various purposes. And if you need to buy inexpensively this type goods in Moscow or any other city, it is better to purchase products from the manufacturer, that is, from us.
If you are interested in a profile - external corner - (in Moscow, for example, or another city) for decorative finishing, then we can offer several types of it:
External corner profiles for ceramics come in several types - L-shaped, rectangular, rounded, C-shaped, corner. Its main task is to hide the ends ceramic tiles ensuring aesthetic appearance. Its installation is carried out while laying the tiles on the wall, since it is held by it, and only on one side. On the other side of the corner, the profile of the tile only covers the end. It is fixed assembly adhesive. The external metal corner is made of anodized aluminum, galvanized steel, and brass.
The anti-vandal external corner profile differs from the first in the way of location and installation. When using this type, the tile does not form a corner joint, but simply rests against the profile with its ends. In this case, the corner of the wall is not covered with ceramics, but this is not visible, since it is covered by a profile for external corners. The installation of this type of product is carried out during the laying of the finishing material and it is fixed with mounting adhesive, so the installation price of this product will be minimal.
If the outer corner has already been completely made, but it is necessary to close the tile joints, then you can buy a profile for the outer corners of the invoice. Such products are straight, with rolled edges and rounded. This metal profile is very easy to install and allows you to completely hide corner joints on walls with already laid tiles. At the same time, it can do a good job of hiding defects on the edges of the finishing material, if any. This external (metal) corner is fixed to the wall using mounting adhesive, which eliminates the need to drill holes in the wall for fasteners.
Besides specified types metal profiles, we can make this product to order in any shape or length. At the same time, the price for such a profile will not differ from the already finished products. So, if you need to buy inexpensively, and even wholesale, these products in Moscow or St. Petersburg, contact ArtProfile.
And since the company sells different types of metal profiles, we have many different products made of metal, including the external corner of the profile for drywall.
And although our production is located in the capital, you can safely contact us even if you live in St. Petersburg or any other city. We will make sure that our products reach you as quickly as possible.

P using thin-walled aluminum profile is attached, the walls are insulated and the ceilings are installed. In addition to the well-known PP type products, there is a wide range of aluminum products that facilitate installation and help save builders’ time, and, accordingly, the customer’s money. What types of profiles there are for drywall, sizes and types, photographs and examples of use are in this material.
Profile construction
An experienced and talented craftsman will be able to build a frame from any profiles he has. There are three main types of aluminum guides that are used for all types of work - these are straight guides PP 50/40, PN 60/27 and PP 27/28. They are intended for creating frames with straight surfaces, but with simple manipulations they can be used to mount curved structures, arches and small architectural forms. However, the work will be easier, and the result will be of better quality, if for each type of work you use material specially designed for this purpose. Drywall profiles, the sizes and types of which are standard, will serve as examples for the description.
The PN type guide has a cross section of 50/40, 75/40 or 100/40 mm. It is used to mark the boundaries of the plasterboard structure, install and secure the racks - the main more structural elements, to which the sheathing sheets will be attached. Its shape is flat U-shaped, it usually has pre-drilled 6 and 8 mm holes for fastening, but is often supplied without perforation. It is most often made of galvanized steel, so the profile is not subject to corrosion. The types of profiles for drywall can be very different, but the basis of the frame is always made up of guides.
The PS rack profile is a product that is used in conjunction with the guides described above and has the appropriate cross-section - 50/40, 75/40 or 100/40 mm. Also made of steel, has U-shape, but during the rolling process additional stiffening ribs are squeezed out on it - one at a time on the ribs, at least three at the end. The ends of this profile are bent inward, which gives additional rigidity. PN and PS are used for installation of vertical structures.
Guides and racks are made of galvanized sheet steel. Whatever the profile for plasterboard: dimensions and types, its configuration, in any case, the choice of material must be determined by strength requirements. Plasterboard walls and ceilings are suspended structures, which are not designed for heavy loads, but during operation they are still possible. The profile frame must provide, first of all, spatial rigidity and not allow the sheathing sheets attached to it to bend and deform.
The thickness of steel for racks and guides must be at least 0.4 mm. The corner profile can be thinner, since it does not experience structural loads. The wider the profile and the longer the unsupported span, the thicker the metal should be. Fasteners are made with a thickness of 0.4 mm.
Helpful information! The standard profile length is 3 meters, but 2.5 guides are available for sale; 2.8; 4; 4.5 and 6 meters long. If desired, the profile section can be extended using special connections.
Fastening elements are intended for the construction of ceilings, since when constructing a wall frame, fastening is carried out using ordinary self-tapping screws at the intersection of profiles. Special elements serve to give spatial rigidity and connect parts located at different levels. Profiles for plasterboard can have different types, so the fastening is selected individually in each specific case.
Example 1: the ceiling is ready for covering, the frame has been completed and insulation has been completed.
Example 2: complex multi-level ceiling with big amount curved lines.
Example 3: alternative connection scheme for plasterboard profiles.
Example 4: classic direct suspension mount.
Example 5: closed arch profile of increased strength.

A corner profile for plasterboard is a metal product designed to design and strengthen the outer and inner corners of plasterboard sheathing on a metal frame. There are two fundamentally different types angles:
Relatively heavy profiles LWi (internal corner) (Fig. 2) and LWa (external corner) (Fig. 3) have the same dimensions - two shelves 60 mm wide, bent 90 degrees relative to each other. The thickness of the metal used is 0.6 mm, which creates sufficient fastening rigidity and stability when the corner profiles are vertically oriented.
In general, they are intended for the formation of thin (from 100 to 200 mm) L-shaped and T-shaped partitions without large quantity cross guides. They fit in size with standard CW rack profiles and are included in the set of profiles for creating independent plasterboard structures.
Corner profile for gypsum board
attached to the guides using self-tapping screws, screwing occurs in the same way plasterboard sheets, only self-tapping screws are used with a flat head.In a certain sense, the perforated corners complement the design. Having modest dimensions of 15x15 mm and a thickness of only 0.35 mm, they perfectly protect and form a single corner of the structure, but at the same time completely disappear under the plaster. The perforated corner can be secured using self-tapping screws or plaster applied as the first layer. In very rare cases they are used adhesive compositions, but only to hold corner profile in the right position.
It's rare that a store can offer
a corner profile for plasterboard with such characteristics, and almost no one can boast of having all possible ceiling, rack and corner profiles in one place. And if you consider that the entire system also requires fittings with plasterboard, then one such trip can cost a pretty penny, but this is at first glance.Our store is one of the few that can offer the entire range of products for installation. plasterboard partitions and ceilings. We can choose from several manufacturers, standard sizes and materials for making profiles.
When choosing profiles for a metal frame, you should pay close attention to the surface texture. And if gloss is the norm for rack and ceiling profiles, then the corner profile for plasterboard sheets is always matte with the natural color of galvanized or stainless steel. It is installed in internal parts, so it does not require additional protection measures (zinc plating, polymer coating)
For independent choice For metal corner profiles for plasterboard, we suggest familiarizing yourself with the following criteria and design features:
Cutting any metal profile is associated with the appearance of burrs and unevenness in the cut itself. For mechanical cutting, a grinder with thin disks is used, and for manual cutting, scissors and metal files are used. In both cases, the corner profile for drywall needs to be cleaned with a file and sandpaper.
For exceptional cases of pre-drilling, standard metal drills HSS, P6M5 and P18 are quite sufficient.
Markings for cutting and drilling are made using a scriber, a caliper (ShTs-1 and ShTs-2) and a core. In order not to damage or crush the corner profile when cutting, you need to place a wooden block under it.
The profile for plasterboard must be chosen as carefully as the material itself for wall cladding and multi-level ceiling systems.
A profile for drywall is not one metal strip, from which you can build anything, as some may think.
Read on to find out what types of profiles there are for drywall, as well as what tools you might need when working with it yourself.
Figure 1 - Types of profiles
What profiles are needed for drywall is a question that every craftsman should ask after familiarizing himself with the initial project. A person who knows his business will not be confused when he sees the abundance of profiles for working with drywall various types. But for those home craftsmen who will be assembling a structure frame for the first time, it is important to know at least the main types of profiles and their differences.
A metal profile for drywall can have several different sections, and at first you can get confused as to what each of them should be used for.
All profiles used when working with drywall can be reduced to six main varieties, four of which are profiles for assembling the structure frame:
In addition, there are also corner profiles (PU marking) - intended to strengthen corners; and a beacon profile (marked PM), used in the construction of a structure for leveling walls.
This type of profile serves as a base - a guide on which the rack profile is attached. A guide profile should be used when the task is to organize wall frame or frame for interior partitions.
This is the main element in the manufacture of wall frames and interior partitions. The rack profile is fixed into the guide, which in turn must be fixed around the perimeter working area(V in this case− along the perimeter of the walls).

This type of profile has the same functions as a regular guide profile, however, this type of profile is designed specifically for the construction of ceiling frames and is attached exclusively to the ceiling.
Photo 3 - Ceiling guide profile
This is another type of profiles used for ceiling work with plasterboard. Main difference ceiling profile from the rack profile is that it must be fixed to the ceiling with special fasteners (which fasteners are best to use and more - read below).

The name of this profile speaks for itself: it is designed to strengthen the corners of the structure after the completion of the main work on covering the frame with sheets of plasterboard.
Photo 5 - Corner profile
Used in plastering work to level walls. Using the fixed beacon profiles, craftsmen are guided in the level of the walls for alignment.
IMPORTANT! Some types of plasterboard structures do not require the construction of a frame; in such cases, plasterboard sheets are mounted without profiles using glue.
Without a profile (without a frame), drywall can be attached in several cases: for example, when the overall weight of the structure is important and the weight that an aluminum frame will give is undesirable, or in the case when the curvature of the walls does not exceed a few millimeters and alignment is possible without a device frame partitions− also for glue (such as “Perlfix” and similar ones).
In addition to profiles, there is also wide range standard parts used in assembling the frame, as well as securing the base of profiles to the walls and ceilings of the room.
Most often used in work:
From the parts described above, fastening them together with several types of screws and anchor dowels, the master will be able to assemble a structure for drywall of any complexity and shape.
Let's consider some types of profiles in more detail, as well as installation of a profile under drywall - methods of connecting elements.
CW 50 (rackmount, wall profile) used for organizing vertical racks metal frames, intended for cladding and partitions made of plasterboard sheets. The profile is mounted only in pairs with a guide profile of the appropriate size. To select the CW 50 profile, the main criteria are the width and height of the partition.
CW 50 is used in plasterboard structures by mounting it in the UW50 profile. These mounted elements are a rack element.
How to attach a profile for plasterboard of this type to a frame: to attach a rack profile to a frame, use screws measuring 3.5 by 25 mm. The fastening grooves of the profile provide convenient connection of elements. This type of profile is suitable for covering structures with sheets of plasterboard on both sides.

СW-75. Production of profiles for plasterboard: this is a galvanized metal profile made by cold rolling - a lightweight and at the same time durable profile. The profile thickness varies from 0.35 mm to 0.55 mm.
Profile shape − straight base and two shelves (a part with sides of the same thickness). Thanks to the longitudinal grooves, it is easy to screw screws into the profile and the procedure for taking measurements is simplified.
CW-75 is used to create a frame for sheathing with plasterboard. The profile is most often used as a vertical stand.
How to connect elements: correctly fasten the profile with screws. It is mounted with a UW-75 profile of appropriate dimensions. Profile element selected based on the thickness and height of the partition being created.

CW-100. Application: this is one of the main elements when installing metal pillar structures. It is used in conjunction with a UW guide profile of similar dimensions.
The CW-100 profile is often used for installation of plasterboard partitions.
Profile production - galvanized cold-rolled metal. The strength of the entire structure largely depends on the thickness of this profile (average profile thickness is 0.35-0.55 mm). Profile CW-100 is a C-shaped part. The width of each side of the profile is 100 mm.
UD-27. This profile is used to guide the CD profile (CD-60) when installing mounted or multi-level ceilings, and a frame for covering walls with plasterboard.
The width of the CD-60 base is 60 mm.
UD-27 is fixed around the perimeter of the workroom. When covering walls, the profile is attached to the ceiling or floor in order to give the structure additional rigidity. The UD-27 profile is attached to the guides with special dowels: for this fastening, the profile has corresponding holes with a diameter of 8 mm, located at a distance of 250 mm.
UW-50. Element used as a guide profile for CW-50 rack profiles. It is used when installing false walls, door frames, and various partitions.
Made of steel.
The UW-50 is attached to the CW-50 using dowels.
Figure 2 — Profile UW-50
In addition, there are many other profiles, including, say, the curved arched PA profile, which serves as the basis for any curved plasterboard structures. The PA profile is made from PP 60/27 profile with a bending radius of at least 500 mm. Even though the profile has a bend, it is not flexible.
To enhance your capabilities suspension system use the T-15 Albes profile. The profile is used for mounting cassettes of formats 300X600 mm, 300X1 200 mm, 600X800 mm, etc. Installation of plasterboard ceilings when using this profile can not be carried out according to templates.
The above is only about metal profiles for drywall. However, in the installation of structures, plastic can also be used - at the end and for finishing external corners.
Do I need special equipment to work with drywall profiles?
Here is a list of tools without which working with your profile will be slow and of poor quality:
Basically, drywall is attached to the profile using self-tapping screws (screws with a round head).
No special instructions are needed here. To bend the profile when assembling the figured frame, it is cut along the end side in increments of 5 cm.
Basically, such work is carried out with metal scissors.

For craftsmen just starting to get acquainted with plasterboard work, one of the primary tasks is to remember the technology for manufacturing plasterboard structures different types and, in accordance with it, calculate the amount of materials required.
For those who are not yet confident in their knowledge and, in general, to speed up calculations, you can find several resources on the Internet that perform all calculations automatically (since it can be quite difficult to calculate the amount of all materials).
Thanks to such programs that operate online (since you do not need to install these applications), you can calculate not only the profile consumption per 1 m² of drywall, but also all the required structural elements. After choosing the area of the room, as well as the type of structure to be mounted, you will receive a detailed list of all the necessary components, the quantity of each element used.
Some of the applications (popularly referred to as “flow calculator”) also indicate the pitch of a profile of one type or another (for example, the distance between ceiling guides), the pitch of fastenings with self-tapping screws, and the thickness of the final structure and other technological details can also be indicated.
You can buy a profile for drywall from the manufacturer at any construction superstore.
The cost of the profile depends on the length and type of product.
So, for example, a linear meter of profile CW 50 (length 4 m) costs $0.85, profile CW-75 - $0.96, UD-27 - $0.35, UW-50 - $0.65 per linear meter .
