[0002] Steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts silanization, pure manganese phosphating, water washing and drying, galvanizing and other rust removal and rust prevention processes. Welds, bolts or rivets are usually used to connect the components or parts. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise and other fields. The roof truss is generally triangular, consisting of upper chord, lower chord and vertical web members and diagonal web members. Depending on the material, there are wooden trusses, steel trusses and reinforced concrete trusses. Reinforced concrete trusses or steel trusses should be used for large-span spaces.
