Types, materials of manufacture- Application and Dimensions + Video Today there is a huge variety of materials for interior decoration of the ceiling and walls. Any finish requires the decoration of corner lines, because the corners are constantly touched and scratched by various objects. And here, plastic wall corners are an excellent solution.

Plastic profiles help to preserve not only the original appearance, but also serve as protection against destruction of the protruding elements of walls. The walls look much neater with them.

Also, the profile can hide uneven walls.

General information

Types of plastic profiles

Plastic profiles are finishing for outdoor work, arched, tiled, ceiling, bathroom, decorative, furniture, for framing doors and window openings.

According to their design features, the profiles are divided:

  • with a rigid structure;
  • with a flexible one.

Products with a rigid structure

Types, materials of manufacture- Application and Dimensions + Video Presented as classic rectangular profiles. Such profiles are made by a method in which longitudinal bending of pvc plates is performed.

This is done when exposed to high temperatures.

Outside, the corner can have a matte or glossy surface, various colors.
Sizes from 2600 to 3000 mm in length, and the size of the shelves from 10 to 100 mm. They also produce different-shelf corners, called arched. They have the peculiarity of bending along the desired radius.

Products with a rigid structure are used for 90 degree angles, as well as for finishing window openings, wall transitions, and serve as protection for wallpaper coverings.


They are presented in the form of plastic strips with a longitudinal groove in the center, thanks to which the material is able to bend at the desired angle. They can be in any color scheme, as well as have a decorative film.
Universal profiles are produced in the form of coils of 50m, and the size of the shelves is from 10 to 100mm. In the case of large deviations from the right angle, corners with a flexible profile are used.

The use of plastic corners


The finishing perforated profile is used even at the beginning of finishing works when plastering and finishing with plasterboard. Arranging it under the wallpaper helps to fix the top layer of putty and level the outer corners.

Note: Finishing profiles do not need to be glued, they are imprinted into the plaster.

Of course, the use of these corners cannot solve all the problems of corners, therefore, as an additional option, a plastic one is installed to the perforated profile. This will help to achieve complete protection of the corners, hide bumps and gaps, and also improve the appearance of the corner.

Also, do not limit yourself to finishing the outer corners. The inner ones are also closed, for example, to mask the transition between different finishes.

Wall corners, depending on the material of manufacture, are:

  • Types, materials of manufacture- Application and Dimensions + Video Polyvinyl chloride;
  • polyurethane;
  • wood fiber;
  • aluminum.

For wooden or tile walls, you will need corners made of the same materials, since plastic will not look here. For all other finishes, pvc corners take the lead.

An exception may be corners made of metal and mdf. They are used to close the street side of the window opening.


The popularity of pvc profiles is justified by the following features:

  • Aesthetics and a huge selection of color solutions;
  • Plastic has sufficient flexibility and is a simple material to use;
  • Plastic material is very easy to cut even with simple scissors, which is especially convenient for fitting to the desired size.

For tiles

Aluminum profiles are used. They are processed using chemical and thermal methods, polished, varnished or laminated.

On one side of the corner, the perforated strip has cuts, it is laid on the surface of the wall or steps. And the second is decorative, having a small protrusion on the inside, into which the lateral end is inserted during corner laying. Also, the tiled corner plays a leveling role in finishing.

Arched corners made of plastic

Types, materials of manufacture- Application and Dimensions + Video Differ from others in that these different side sizes are very flexible. They come in a color and decorative solution.

They are produced up to 3m in length.

Arched corners help hide the line between drywall and slope. This method of arranging arched openings is the simplest and most inexpensive. However, you need to have an idea of ​​how the plastic corner is bent correctly, and here simple corners will not work.

Sticking a simple corner to drywall can cause the profile to peel and break.

Therefore, it is better to immediately use a special arched profile.

As a rule, profiles with a length of 25 to 30 millimeters with a reduced side shelf are used for arches. Due to the fact that the side shelf is slightly smaller, the profiles can bend well, which prevents them from moving away from the edges when gluing.

Important: When gluing the corner to the arch, first mark the places of their contact for applying the glue. If this is not taken into account and done by eye, then a large amount of glue will be wasted.

If the arch has a small radius, then the corner will have to be bent strongly enough that even a special corner may not withstand and warp. In such situations, use the hot bending method. At the same time, fixing the corner from one end and heating it up to 60-70C, while pressing it against the drywall. During the cooling of the material, roll it along the profile with a paint roller.

Window openings and doors

Replacing old windows with double-glazed windows entails repeated plastering of the slopes and the need to select material to close the outer corner.

Traditional plasterboard slopes and perforated metal corners on the outer corner contribute to perfect surface leveling. However, even this is not an ideal solution, since the window is in private use and damage to the edge cannot be avoided. Therefore, a plastic corner is simply necessary here. The dimensions of the plastic corners depend on the dimensions of the window opening.

For example, 20 * 20 mm profiles are suitable for a drywall-wallpaper corner, and 25 * 25 mm profiles are taken to move from mdf board to wallpaper.

You will also need corners to close the gaps between the window and the slope and between the window sill and the wall. Here you will need T-shaped corners.
Many people think that it is not necessary to close the line between the slope and the windowsill. However, a plastic window sill has the ability to spring even from small loads, so after a while the material for sealing the corner joints may crumble. Maybe here it will be more humane to close this gap with a profile.


Also, plastic corners are often used when sealing the seams between the bathroom and the tiled wall. In addition, plastic feels great in a humid atmosphere.

Another place where you just need a plastic corner is the front door. When replacing the front door, it is also necessary to carry out decoration work. After finishing, whatever one may say, the end of the cladding panels remains visible.

It must be closed, since this, firstly, will not allow dirt to accumulate in the corners and will give the appearance of completeness.
