Roof fencing is an important condition for safety on the roof

A roof guard is an elementsecurity, installed along the perimeter of the roof, having the appearance of a handrail or curb and designed to prevent people from falling. Roof fencing consists of racks installed along the edge of the roof, and horizontal rails fixed on these racks in several levels. The height of this fence is regulated, and for ease of movement on the roof it can be installed on a bridge for the roof. When selecting the material for the roofing enclosure, account should be taken of the structure and material of the roof itself, as well as the conditions of its operation. For aggressive environments, designs using more durable and durable materials are used. Also, regular fencing checks should be carried out, the frequency of which depends on the conditions in which they are used.

The choice of roofing material depends on the differentfactors. There are many of its kinds, suitable for certain conditions. Transitional bridges, for example, have two main functions: ensuring safe movement along the edge of the roof and preventing ice and snow from falling from the sloping roof. The length and width of such a bridge can be increased if necessary, and to provide greater security it can be equipped with handrails.

There are many other types of fencing, andthey all fall into two main groups. Roof fencing for the roof is designed for houses and office buildings, where the roof is used as a useful space. The most popular is now in large cities, suffering from a lack of free space. On such roofs are arranged viewing platforms, open spaces, breaking gardens, etc. Of course, in this case, a more reliable fencing is required, the strength of which is determined by the standards. The safety features are regulated by the GOST of roofing 25772-83, which determines the strength, material and height of the fence. The latter is calculated based on the height of the building itself, which is due to the increase in wind force at the top. The roof guard can also be reduced in height if it is installed on the parapet.

In those cases where the roof is not designed forconstant use, the requirements are not so strict. It is necessary that the height of the fence should not be less than 60 centimeters for a safe stay on the roof during repair work. The main material, from which the roofing is made, is galvanized steel - because of its strength and resistance to corrosion.
