Metal structures are an efficient construction system, with high structural resistance capacity, avoiding the occurrence of pathologies typical of reinforced concrete structures (cracking, among others) and presenting a good seismic performance. It is currently a privileged system when compared to traditional methods. Already applicable to all types of construction, beyond the industrial area, both for its physical and mechanical properties, as for its fast construction process, versatility and sustainability, being able to overcome large spans and meet the most varied architectural challenges. It also allows the disassembly and expansion, with high reuse of the existing building and practically without construction waste.
