Roof protection is a safety element installed along the perimeter of the roof, in the form of a railing or curb and designed to prevent people from falling. The roof fencing consists of racks installed along the edge of the roof, and horizontal rails mounted on these racks in several levels. The height of such a fence is regulated, and for ease of movement on the roof, it can be installed on a transitional bridge for the roof. When choosing a material for roofing, one should take into account the design and material of the roof itself, as well as the conditions of its operation. For aggressive environments, structures made of more durable and durable materials are used. Guards should also be checked regularly, the frequency of which depends on the conditions in which they are used.
The choice of roofing material depends on various factors. There are many types of it, suitable for certain conditions. Walkways, for example, have two main functions: to ensure safe movement along the edge of the roof and to prevent ice and snow from falling off the sloping roof. The length and width of such a bridge can be increased if necessary, and to provide morefor security, it can be provided with a railing.
The simplest and most common type of roofing material is a simple metal fence. Its design is elementary: it is represented by vertical supports, securely fixed on the edge of the roof, and horizontal bars, usually two. Dimensions are individual, as is the material used, and the price mainly depends on these two factors. In Europe, this type of fencing is a necessary requirement, and its installation is mandatory, but in Russia this has not yet been reached.
There are many other types of fencing, and they all fall into two main groups. Roof railing for occupied roof is designed for houses and office buildings where the roof is used as a usable space. This is most popular now in large cities suffering from a lack of free space. Observation platforms, open spaces, gardens, etc. are arranged on such roofs. Of course, in this case, a more reliable fence is required, the strength of which is determined by the standards. Safety characteristics are regulated by GOST 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 associated with an increase in the strength of the wind above. The roof railing can also be reduced in height if installed on a parapet.
In cases where the roof is not intended for permanent use, the requirements are not sostrict. It is necessary that the height of the fence be at least 60 centimeters for a safe stay on the roof during repair work. The main material from which the roof railing is made is galvanized steel - due to its strength and resistance to corrosion.
