Fire protection of steel structures are also performed using:
-
Silicone-cement boards
-
Drywall
Thanks cladding steel structures can get resistance at R240 ( do 240 High index-minute fire resistance).
Selection of board thickness is based on the required fire resistance class and sturdiness factor section steel profile U / A. The decisive advantage of slab systems is the ability to "hide" steel construction, making them aesthetically pleasing Position.
