Profiles for drywall. Dimensions of the profile for plasterboard

The profile is a rack made of galvanized cold rolled metal. With its help it is possible to construct a skeleton of any complexity. Vinyl and metal profiles for gypsum board are used in the modern building industry. Dimensions and materials are suitable for all installation structures. Before you begin to work, you should know all kinds of profiles used in construction.

Types of profiles

The guide (called UD) is installed along the entire perimeter of the room (if it is a ceiling) or on the floor, ceiling and parallel walls (if it is a wall). It is used to create the plane of the future framework. The profile of the guide for plasterboard, the dimensions of which are very convenient in design designs, are of different quality. The strength depends on the thickness of the material being manufactured. On the ceilings, thicker steel is used. The product of a thin metal is used for wall covering.

Bearing (denoted SD) - this is the supporting profile for gypsum board. Its dimensions (thickness and length) are different, as in the guides. The thinner the steel, the greater the number of fasteners installed. Designed for the final completion of the design. Is responsible for the reliability and rigidity of the frame. It takes on all the load, so it should be made of good galvanized material. Mounted by inserting into the guide (UD). It is calculated so that the extreme sheet of gypsum board ends in the middle of the profile. The main criteria for selection are the width and height of the partition. It is screwed from each edge with small self-tapping screws ("fleas").

In addition to the two basic, other types of profiles for drywall are used. Their dimensions are very similar, but the functions differ from each other:

1. Angle profile (PU) - is designed to strengthen the outer corners. It is fixed to the plasterboard base with putty. Also called a perforated corner. It is used in window or door slopes, outside corners of walls and boxes. On the walls performs the function of a beacon. With its help, the corner of the wall comes out even and sharp.
2. Mayachny (PM) - if the walls are very crooked, special beacons are placed on the plaster, then putty put between them and pulled up by the rule.
3. Ceiling guide - has the same functions as a normal profile, but it is much stronger. It is made especially for ceiling skeletons.

Vinyl profiles

Profiles for drywall, the sizes of which are different, suitable for any user needs. To qualitatively complete the installation of structures, it is worth using vinyl profiles, the surface of which is easily processed. They are designed for end, outside corners and non-standard walls. Protect from moisture, give perfection to the edges and connect the structure with window blocks and doors. There are several of them:

1. Arch (PA) is a curved arch profile. Used in curved plasterboard structures. The radius of flexibility is 500 mm. Particularly suitable for finishing columns.
2. J-profile is very common. It is made of hard vinyl. It is used to decorate the edge of plasterboard and it is easy to put on it. Well painted.
3. A cable profile is a specially designed element. It is used to install a fiber optic cable. A soft cord is put inside, so that it does not get putty.
4. The marker of a semicircular corner is a high-quality tool, with the help of which even fine corners are created.
5. Rotate -serves to ensure consistent cable uniformity.

Dimensions of profiles

For each design idea, you can choose the right profile for drywall. Dimensions are designed so that when mounting the structure, many unnecessary pieces are not thrown out.

With the help of a large assortment of different dimensions, it is possible to choose the width and length of the element.

Additional fastening element

Sometimes builders face problems when fastening profiles for drywall. Their dimensions may be smaller than the required design. Therefore, it is necessary to use additional fasteners.

1. The profile connector is a fastening element that connects two carrier rails to each other. It is inserted into the ends of two joined elements and fixed by two "fleas" on metal from each side.
2. Suspension - come with an anchor clamp and straight. This is a metal plate, easily bend in the form of the letter "P" and fixing the profile to the ceiling.
3. Crab is a fastening element for installing jumpers located between racks.

Tools for installation works

When working with a profile, you should have some tools:

• Scissors for metal - they cut or cut off the rail;
• Roulette - serves for measurements;
• The cutter - pierces apertures in details of a skeleton;
• Marker or pencil - assigns cut lines;
• Staprofilm - pliers for fastening.

Mounting and fastening

An important factor is the correct erection and fixing of the structure. First, the upholstery cord is repulsed by the level: for the top - horizontal, and for the walls - vertical. Guides are exposed and attached to the wall using a dowel-nail (size 6x40 mm or 6x60 mm).

The carrier is mounted in the UD. Then the profiles for the plasterboard are horizontally distributed. The dimensions of the step are 40 cm, but it should be taken into account that the joint of the sheet must be in the middle of the strip. To the ceiling along the vertical lines in the form of the letter "P" reinforced suspension brackets are fixed with dowels "beech". The horizontal metal bars of the LED are leveled and attached to the plates with the help of "fleas".

After the completion of all work on the structure of the frame, sheets are screwed onto the profiles for gypsum board. The dimensions of the metal screws for the material are 25 mm or 35 mm. The step size is 15 cm.
