One of the transparent protective corners

Shapes and sizes

The finished corners usually have an angle of 90 °. The angle itself is not always sharp, there are options with a rounded one. By type, the corners for protecting the corners of the walls are divided into:

  • tough
  • external;
  • internal;
  • flexible (plastic, rubber)
  • universal.
  • Universal corner from MDF

    Questions can only be universal. These are two strips of plastic or MDF connected by a thin strip of flexible material of the same color. Thanks to this connection, you can make an obtuse or acute angle, internal or external. without much difference. But in terms of protection reliability, it is inferior to rigid ones. after all, the flexible part is quite thin.

    It is also worth knowing that the corners can be with shelves of the same and different widths. often they are found with the same, but it is quite possible to find those in which one is wider, the other is narrower.

    Types, shapes, sizes

    The shelf width differs from manufacturer to manufacturer. Plastic, for example, can have shelves from 10 mm to 50 mm. MDF corners are minimally made with a shelf width of 20 mm, metal corners. from 10 mm, but the maximum shelf length is 90 mm (aluminum). So there is plenty to choose from.

    Arch decoration

    Arch design is often a problem. In general, there are not many outside corners in the apartment, but they are mandatory on the arch. And in the aisle, they very often hurt. Either with furniture, then with another load, or simply a resident who did not fit into the opening. And there are no questions with the direct part, then the rounded part can be a problem.

    And not only in the doorway can there be an arched vault

    In general, universal corners can be used for the arch. They are flexible, which is very convenient. There are flexible non-universal. plastic, made of a special polymer of increased elasticity.

    But in general, corners with different widths of shelves are used to decorate arches. They are even called arched. They have one shelf 10 mm (outer), the second. inner. 30 mm and more. They bend easily. Do not twist it into a donut, but it is not difficult to get any curvature of an arc. It will only be necessary to use a secure fixation while the glue dries.

    This is an arched plastic corner

    If you want to bend an ordinary corner, you can do this by heating the plastic. For this job you need a building hair dryer. Regular. for hair. will not work, since its temperature is too low. We also need a template according to which we will bend the plastic corner. Take a piece of fiberboard, screw in screws or hammer in nails, forming the profile you need.

    So you can arrange the corners of the arch with protective corners.

    How to Polish and Shape Plastic Edges

    Bending starts from the middle. You warm up the area by constantly pressing on the middle, and with a hairdryer moving from the center to the edges. So it is necessary to bring the corner to the desired curvature and leave it in this position to cool. So that it does not straighten, holes are made for the second row in parallel with a number of self-tapping screws. The distance between the rows is equal to the width of the corner shelf. After the plastic is bent, insert and slightly tighten the screws. After the plastic has cooled down, remove them.

    How to cut finishing corners

    Almost always, the corners have to be cut to protect the corners of the walls. They are sold in slats from 2 to 3 meters long. The cutting tool is selected depending on the type of material. For wood and metal, thick plastic, you need a hacksaw, but the blade is different. for wood, and with a small tooth for metal or thick-walled plastic.

    Thin plastic can be cut with a construction or office knife, sharp scissors. If you need to cut perpendicularly, it is easier to use scissors. We cut them to the corner on both sides, bend the corner, cut the remaining millimeters with a clerical knife. If there are flaws, they can be easily corrected with the same knife or sandpaper with a very fine grain (polishing).

    How to cut a protective plastic corner (PVC)

    If the plastic corner needs to be cut along the fold, we cut it along the inner corner with a clerical knife. Cutting through to the full thickness does not make sense. You just need to leave a noticeable strip. Then we fold back the piece to be removed. It comes off at the cut. Remove irregularities with a knife or sandpaper.
