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 by simple manipulation 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.
Frame elements
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. It is also made of steel, has a U-shape, but during the rolling process additional stiffening ribs are extruded onto 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.
- The connecting longitudinal bracket is an element that allows you to join and thus extend the profile. It is a spring, fastened with self-tapping screws on the sides.
- The plinth strip is a fastening element that is used to mark the boundary of the sheathing sheets at the bottom, top or sides. The outer edge is perforated, meaning the visible part is supposed to be filled with putty.
- A cap profile is a special type of profile that can be used without guides, and is mounted directly to the wall or ceiling. Used as a frame for insulation.
- Z-profile – used as additional stiffeners.
- L-shaped profile - traditionally used as a starting or finishing element in structures with open ends.
Sizes and characteristics
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 that are not designed for heavy loads, but they are still possible during operation. 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.

Mounting options
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.
- Suspensions are the most common type of fastener, which is a perforated plate with special notches that bends and turns into brackets of various configurations. The end of this bracket is attached to the ceiling, and the free ends hold the ceiling profile hanging.
- Corner joints are brackets that allow fastening from the end of the profile.
Examples of units and structures
Example 1: the ceiling is ready for covering, the frame has been completed and insulation has been completed.
Example 2: a complex multi-level ceiling with a lot of curved lines.
Example 3: alternative connection scheme for plasterboard profiles.
Example 4: classic direct suspension mount.
Example 5: closed arched profile increased strength.

The profile for drywall is long metal element, made from low carbon galvanized steel by cold forming on automated roll forming lines. The profile serves as the main material in the manufacture of a metal frame for the installation of gypsum plasterboard sheets.
Before the appearance steel profile under plasterboard for fastening gypsum plasterboard sheets in construction was widely used wooden beam, or a sheet of drywall was simply glued or fastened with self-tapping screws directly to the wall or ceiling. Wood, even with protective coatings applied, does not tolerate fluctuations in temperature and humidity, is prone to cracking and deformation, is not resistant to fungus and mold, and, in addition, is a fire hazard and is by no means cheap. And a sheet of drywall that is simply screwed to the ceiling leaves no chance of getting a perfectly flat surface for future walls and ceilings.
The appearance of steel profiles for drywall has significantly simplified construction finishing work. Today, metal profiles for gypsum boards are used not only when constructing a load-bearing intermediate frame for installing sheets of gypsum boards and GLV, but also when creating various decorative elements interior So, for example, decorative frames can be made from galvanized plasterboard profiles.
Drywall is a revolutionary material in the construction market. Since its appearance, leveling walls and ceilings has ceased to be a problem. It is widely used in construction and interior decoration. Its flexibility is a godsend for designers who use drywall to implement their most daring design projects for apartments and offices. But in order to attach plasterboard to a ceiling or wall, or to make a partition out of it, you cannot do without special profiles for plasterboard to hold it. Various metal profiles will allow you to quickly and easily make the desired frame to which the gypsum board sheets will be attached.
The profile varies in thickness and metal composition, from 0.4 to 0.7 mm. The tolerance is usually up to 0.05mm. The rule here is simple: The thicker the steel, the better. stronger design. In non-load-bearing structures, the use of a profile with a thickness of 0.5 mm is allowed. We do not recommend taking thinner ones. The savings are often not justified, since on a thin profile you have to use more suspensions, which neutralizes all the attractiveness of a cheap profile.
You should pay attention to the metal itself. If it is soft, then the screws will scroll, even with a large thickness of steel.
Our company, Synergy Stroy, offers products from Russian manufacturers of galvanized steel profiles, in addition, we control each new batch. Our profile for gypsum plasterboard complies with the stated technical characteristics.
Main types of profiles for drywall:
- Profile for plasterboard guide (PN) - without it it is impossible to build frames for leveling walls and ceilings, or build partitions. It has a U-shape and is used in conjunction with rack-mount and ceiling profiles of the same standard sizes. The sections of the guide profile for gypsum boards are 50X40mm, 65X40mm, 75X40mm, 100X40mm. These are the most common sections, but some manufacturers may have their own sizes. Therefore, it is important when purchasing profiles for drywall to choose Construction Materials one manufacturer.
- Rack profile for gypsum plasterboard (PS) – used as a rack when creating a frame for drywall. The profile is C-shaped. Additional rigidity of this profile is provided by corrugated fastening shelves. The height of the shelves is usually 50mm, the width is the same as that of the guide profiles for plasterboard from 50 to 100mm.
- Profile for ceiling gypsum plasterboard (PP) – designed for fastening suspended structures, widely used for suspended ceilings. This profile has a C-shape. The ceiling profile shelves have a height of 27mm, the width can be different. The most typical sizes are 60mm, 28mm. The ceiling profile for plasterboard is marked PP60x27, where 60 is the width of the profile, 27 is the height of the walls. The edges of the ceiling profile are curved inward.
- Arched profile for gypsum boards. IN modern design The design of doors in the form of arches is widely used, or the installation of a complex curved ceiling is used. For these cases, a special arched profile is provided, with the help of which various bends are created. There are metal or plastic profiles. Hardware more durable, but due to its design, including holes, cuts and other special devices, this does not affect their flexibility, and the arched profile can take on almost any curved shape.
- Corner profile for drywall. Can be made from various materials, depending on the purpose. Thus, steel corner profiles are used to strengthen facades, aluminum ones are used to reinforce corners and door slopes, protecting from mechanical damage. Galvanized corner profiles contain holes filled with putty; they are used for additional finishing works. PVC profiles provide protective and decorative functions. They prevent drywall from chipping and are a design element.
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 just 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.

Types of profiles for drywall
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:
- guide profile (marking PN/UW);
- guide ceiling profile (marking PNP/UD);
- ceiling metal profile (marking PP profile/CD);
- rack profile (marking PS/CW).
In addition to this, there are also corner profile(PU marking) - intended for strengthening corners; and a beacon profile (marked PM), used in the construction of a structure for leveling walls.
Guide profile
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.
Rack profile
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).

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

Corner profile (reinforced)
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
Beacon profile
Used in plastering works by leveling the walls. Using the fixed beacon profiles, craftsmen are guided in the level of the walls for alignment.
IMPORTANT! Some types plasterboard structures do not involve the construction of a frame - sheets of plasterboard in such cases are mounted without profiles on 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).
Additional fasteners
In addition to profiles, there is also a wide range of standard parts used in assembling the frame, as well as securing the base of the profiles to the walls and ceilings of the room.
Most often used in work:
- straight hangers and hangers with an anchor clamp (used to secure the ceiling profile to the ceiling);
- crab connector (used to create cross connections at a 90° angle in the frame, which are present in almost all designs);
- connector and extension (these types of additional fasteners are used to connect to various combinations profile segments between each other).
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.
Profile for drywall: profile sizes and other useful technical characteristics
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) is used for organization 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.
Technical characteristics of CW 50
- Profile size: 50x50 mm.
- Thickness: 0.42 mm.
- Length: 3 m, 4 m.
Photo 7 - Profile CW 50
СW-75. Production of profiles for plasterboard: this is a galvanized metal profile made by cold rolling - lightweight and at the same time durable profile. The profile thickness varies from 0.35 mm to 0.55 mm.
The profile shape is a 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. The profile element is selected based on the thickness and height of the partition being created.
Technical characteristics of CW-75
- Size: 50x75 mm.
- Thickness:0.42mm.
- Length: 3 m, 4 m.

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.
Technical characteristics of CW-100
- Profile size: 50x100 mm
- Thickness: 0.42 mm
- Length: 3m, 4m
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.
Technical characteristics of UD-27
- Size: 27x28 mm
- Thickness: 0.37 mm
- Length: 3m, 4m
UW-50. Element used as a guide profile for rack profiles CW-50. 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.
Technical Parameters of UW-50
- Size: 40x50 mm
- Thickness: 0.42 mm
- Length: 3m, 4m
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.
Profile tool
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:
- metal scissors for cutting profiles;
- clamp profile - pliers that fasten the profile;
- profile cutter - a tool necessary for piercing holes in frame parts, since it is impossible to assemble a frame without fastening the profiles;
- The divider is used to connect profiles in corners.
- How to attach drywall to a profile?
Basically, drywall is attached to the profile using self-tapping screws (screws with a round head).
- How to bend a metal profile?
No special instructions are needed here. To bend the profile when assembling the figured frame, it is cut along end side in increments of 5 cm.
- How to cut the profile?
Basically, such work is carried out with metal scissors.

Profile calculation for drywall
For masters just starting to get acquainted with plasterboard works 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.
Profile for drywall: price
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 .
How much does a drywall profile cost:
- in Moscow - from 11 to 37 rubles. per linear meter depending on the type and length of the product;
- in Kyiv - from 2.76 to 8.91 UAH. per linear meter depending on the type and length of the product.
