Product Description

Steel structure is a structure composed of steel materials, which is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of profiled steel and steel plates. Welds, bolts or rivets are usually used to connect the components or components. Because of its light weight and simple construction, it is widely used in large-scale factory buildings, venues, super high-rise and other fields.
