The steel structure is a load-bearing structure composed of steel plates and hot-rolled steel. Compared with structures of other materials, it has the following characteristics:
The steel structure is small and light in weight, convenient for transportation and installation, as well as for assembly, disassembly, and expansion. It is suitable for structures with a large span, high height, and heavy load.
Steel has a high strength and light structure. Compared with masonry and wood structures, steel has higher density but higher strength, so the ratio of density to strength is smaller. Under the same load, the steel structure is better than other structures.
The steel has high strength, good plasticity and toughness, and strong resistance to impact and vibration.
The high degree of industrialization of steel structure, factory manufacturing, site installation, high processing accuracy, short manufacturing cycle, high production efficiency, and fast construction speed; steel structure buildings have strong platform structures, roof structures, tall background walls, etc. The sense of time and changeable appearance are suitable for expressing the imagination of designers.
Residual materials and debris generated in steel structure processing and manufacturing and abandoned and damaged steel structures can be re-smelted into steel for reuse. Therefore, steel is called green building materials or sustainable materials.
