Selecting the appropriate wall profile during drywall installation is crucial for creating a sturdy and long-lasting structure. The framework that holds the drywall sheets in place is provided by wall profiles, so choosing the right sizes is essential to the project’s success. Numerous manufacturers provide a range of profile sizes, each tailored to satisfy particular demands and building specifications.
You can save money on materials and prevent needless waste by being aware of the available sizes and how to select the appropriate one. This post will discuss the standard sizes of wall profiles from various manufacturers and offer helpful installation advice to reduce waste. Knowing these details will make your drywall project go more smoothly and effectively, regardless of whether you’re a professional or a do-it-yourself enthusiast.

What is the profile for drywall for walls
The page’s navigation
You must determine what kind of profile is required for drywall for walls if you wish to mount the structure independently on vertical surfaces. Metal products come in a variety of forms, sizes, and uses. Two primary types of profiles are required for wall lathing, in addition to other materials.
Understanding the different sizes that different manufacturers offer when selecting wall profiles for drywall installation is essential to guaranteeing a seamless, effective process. This article examines the common sizes that are available, offers guidance on choosing the appropriate size for your project, and gives helpful suggestions on how to reduce waste during construction in order to save time and materials.
How to choose sizes
The contemporary market is brimming with different kinds of metal strips intended for gypsum board installation. One type is used depending on the kind of structure being built.
The metal strips are:
- Guide for ceiling structure PNP (UD).
- Ceiling – PP (CD).
- Rackmount – PS (CW).
- Guide – PN (UW).
- Corner PU.
- Lighthouse view.
- Arched – PA.
The primary materials used to construct a plasterboard structure are the first four categories. The remaining components are extras that add to the rigidity.
Every kind has specific measurements. The principal ones are:
| No | Product name | Its markings | Dimensions |
| 1 | Ceiling guide | PNP – UD | 27×28 |
| 2 | Ceiling | PP – CD | 27×60 |
| 3 | Guide | Mon – UW | 50.65.75.100×40 |
| 4 | Rack | PS – CW | 50.65.77.100×50 |
You need the following supplies to make a lathing in the wall alignment: lead PN, rack P.S.
What dimensions do plasterboard wall profiles come in?
In order to align walls, the following items are utilized:
- Load-bearing CW – 50×50, 75×50,100×50, 125×50 and 150×50 mm.
- Guide UW – 50×40, 75×40, 100×40,125×40 and 150×40 mm.
- Length of rack profile from 2.6 m to 4 meters. Guide is produced 3-4 meters. There are differences in appearance: on some there is a rollback of 2 strips for fastening, and on others there is an H-shaped cutout for cables.
Types
A PS rack type, commonly referred to as wall and frequently used in the construction of plasterboard surfaces, is utilized in the wall structure.
Its sides are slightly curved inward, and there are two longitudinal channels running along its "back."
Strips of a length that allows for calculation and waste-free work are produced by manufacturers. The following are the dimensions:
- length 2.5-4 meters;
- width 6 cm – this is convenient when installing 2 sheets of gypsum board. 3 cm on 1 sheet and the same on the other. The joint is strong;
- height of the side parts 27 mm.
Use this guide strip to help create a drywall frame on the wall. The foundation of the entire structure is this. A straight hanger connects the wall to the profile, the racks are secured to the guides with self-tapping screws, and the product is fastened to the floor and ceiling. A rack guide is placed into the product and secured with dowel nails.
European UW and PN guide marking. It is not curved; it is a straight shape. Product dimensions are 3 meters long, 2.7 cm wide, and 2.8 cm high on the sides. Product has a 0.5 mm thickness.
Use these materials in addition to metal strips to make a drywall frame base:
- Direct hanger is a perforated strip. It is bent on the sides, and the center is attached to the wall. A rack profile is fixed to this hanger, it is also applicable in a metal frame on the ceiling.
- Connectors. These metal products are installed when it is necessary to connect 2 profiles. Designed for rack and ceiling profiles.
- Crabs – mounted in the ceiling structure, but if a complex vertical frame is created for a figured plasterboard structure, or the lathing is reinforced for hanging heavy objects on the wall, then a crab (connector) is used.
Metal strips and straight hangers are fastened to the rough base with dowel-nails.
What kind of profile is required for walls made of plasterboard?
The foundation of the entire wall frame is a guide strip composed of galvanized metal PN (UW). It is fixed to the wall and ceiling in such a way that it resembles a mirror and doesn’t move. Additionally, they must be fastened to opposing walls. An even quadrangle that forms a plane will result. Dowel-nails are used for fastening, spaced 20–25 centimeters apart. To secure the first dowel-nail, you must take a step backwards, five centimeters from the profile’s edge.
Next, rack elements are held in place by straight hangers that are fastened to the wall in accordance with the markings. Fixing also involves the use of dowel nails.
The rack PS (CW) receives the PN (UW) guides. Bug screws are used to fix them. A level is used to adjust the plane’s levelness, and screws are used to secure the racks to the hangers.
Crossbars are positioned every 40 cm to increase the structure’s rigidity. They are attached to the vertical racks with crabs after being cut from rack PS (CW).
Is it possible to adjust the dimensions
A typical product length from a factory is three to four meters. Different product lengths are required, though, when building a wall with figured elements or a flat partition. To accomplish this, metal components are either cut or extended to the required length for the structure.
Techniques to trim the profile:
- Scissors for cutting metal. The product can be cut evenly only along the marked lines. A disadvantage is considered to be slightly bent edges after cutting. The cut strip is placed on a flat surface and leveled by tapping with a hammer.
- A hacksaw for metal is not a very convenient method. There are small shavings from cutting the product. However, the cut will be smooth.
- Angle grinder. Sparks fly in all directions when working with an electrical appliance.
With scissors made in the Soviet Union, you can cut the profile without choosing to.
Extension of the metallic component. Use two strategies to boost the product:
- The use of the extension cord is a metal durable part, covered with a protective layer of corrosion. It is applied to the edges of two planks and fixed with self -tapping screws.
- Homemade extension cord from the guide Mon. It is necessary to cut off from the product 10 cm and attach to the edges of the profiles. Fixation is with clip self-tapping screws.
The frame’s metal element’s length is easily adjustable. All you have to do is take precise measurements and markings. Remember that millimeters can make a big difference in how even the structure is, so pay close attention to them.
There are specific sizes and material thicknesses for the profiles used to create a frame structure on the wall. They are galvanized, which is an anti-corrosion coating; metal products are unaffected by humidity. You must determine the number of profiles based on the room’s measurements before making a purchase.
| Manufacturer | Profile Size (mm) |
| Knauf | 50×50, 75×50, 100×50 |
| Gyproc | 60×27, 70×40 |
| Rigips | 50×50, 70×50 |
| Recommendations | Choose profiles based on wall height and drywall thickness to minimize waste. |
To achieve a smooth and even finish during drywall installation, it is essential to comprehend the various wall profile sizes. You can choose the best option for your particular project needs by being aware of the options offered by different manufacturers.
Selecting the appropriate profile size reduces waste in addition to assisting in the construction of a strong structure. This guarantees a more economical and time-efficient use of resources during construction.
You can maximize the effectiveness of your drywall installation and make sure that the profiles and drywall sheets line up precisely by paying attention to the advice and suggestions given. Your walls will look more polished and long-lasting with this method.
