Revision hatches are used to provide free access to the laid internal engineering communications. Hatches must have a mandatory set of the following characteristics, such as structural strength and long service life. Since to carry out work on replacing the hatch, it is necessary to carry out finishing work in the area of its installation.
Depending on the scope of use, specific values of the parameters of the inspection hatches are calculated depending on the class of external loads acting on them. Hatches are divided into plastic, cast iron, recessed and tile hatches. Hidden hatches are hidden under the outer wall covering. Inspection hatches under tiles are usually mounted in bathrooms, kitchens, industrial laundries and other rooms with high humidity, where tiled tile. Installation of hatches is carried out before the start of the tile finishing of the wall section selected for installation of the hatch. The hatches built into the wall do not spoil the overall picture of the finish. Such hatches by the way of opening can be push-down, sliding and removable.
At the same time, hatches for tiles have a number of design and technical features, which are associated with a significant weight load of finishing materials. Tile hatches are easy to install and operate, they are mounted both on the wall and on the ceiling, they can be made of any material. The hatches can be equipped with a magnetic locking device or a key lock to restrict access. Inspection hatches are an excellent solution for residential, public buildings and other structures.
