The top manager tells in detail about the characteristics of the roller shutter system, which affect its wind resistance. In particular, we are talking about the thickness of the aluminum strip, which is used for the manufacture of the profile, as well as the quality and density of the foam filling. The thicker the tape, the more evenly the foam is distributed, the more rigid and resistant to loads the roller shutter. Do not forget that the wind resistance of a roller shutter profile directly depends on its width.
Depending on the wind strength that the roller shutter can withstand without compromising its functional characteristics, it is assigned a wind resistance class in accordance with GOST R 52502-2012. Accordingly, in order to be sure that the roller shutter system will reliably protect against wind of a certain strength, it is necessary to know its class.
Zoning in accordance with wind loads is determined by SNiP 2.01.07, which is used in the design and construction of buildings in the CIS countries. This document divides the entire territory into seven wind regions, each of which has its own wind pressure.
Thus, when choosing a roller shutter system, you need to find out in which wind region the object is located, and opt for a structure of the corresponding class. It is important to pay attention to the value of the wind pressure, which was taken as a basis for calculating the wind resistance class of the roller shutter.
