Metal Structures Benefits
The metals are indisputable and universal modern construction materials. Designers prefer Metal structures, in particular Steel structures, when choosing a main load-bearing structure of some of the most complex and responsible buildings and structures implemented on the territory of Bulgaria and abroad. Above all, metal structures achieve the functional versatility of load-bearing structures in general, regardless of their application (in construction, mechanical engineering, industry, etc.), regardless of their type, shape, size, needs of buildings and structures. The expansion of steel structures as the main load-bearing structures of buildings and facilities has given considerable freedom to the realization of large-scale buildings, large openings and extremely complex geometries. Another important advantage of metal structures that should not be underestimated is their high seismic stability. The metal has the property of redistributing the effort and stresses during overloading, resulting in a relaxation of the stress state in the metal supporting structures without compromising their load-bearing capacity. Weighing the advantages, it is impossible not to emphasize the opportunities offered by metal structures, where a reconstruction, reinforcement and modernization of already existing buildings and structures are required. In this category, metal structures are a clear winner over reinforced concrete structures. All sceptics would provoke questions about the tendency of metal structures to corrode and their fire resistance.
