Steel structure is a steel-based structure and one of the main types of building structures. The structure is mainly composed of steel beams, steel columns and steel trusses made of section steel and steel plates, and the components or parts are usually connected by welding, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields.
