Steel structure is a type of building structure mainly made of steel. It is an engineering structure made of section steel and steel plate through welding, bolting or riveting. Each component or part is usually connected by welding seams, bolts or rivets. Because of its light weight and simple construction, it is suitable for single-storey large-span buildings as well as multi-storey or high-rise buildings. It is widely used in large factories, Fields such as venues and super high-rise buildings. Steel structure is easy to rust. Generally, steel structure needs to be derusted, galvanized or painted, and regularly maintained. Steel structure is one of the more common structural forms in modern construction engineering.
