Fireproofing of metal structure

Metal structures have many advantages, among which we can find: their slenderness compared to other types of structures, the possibility of executing large spans and their versatility.

On the other hand, its main drawback would be its rapid heating and a significant loss of its bearing capacity at relatively low temperatures (usually 500 ºC).

In addition, in order for metal structures to comply with current regulations on the fire resistance of building structures, it is common for additional treatment to be applied for this purpose.
