Steel structures typically feature shapes such as H profile, I-beams, hollow structural sections (HSS), channels, angles, and plates.
The main type of steel structure are the frame structure, the truss structure, the grid structure, the arch structure, and the portal rigid steel frame.
Additionally, steel structure has a steel arch structure, arch bridge, beam bridge, cable-stayed bridge, and suspension bridge.
Each type has its unique advantages and applications, making steel a versatile material in construction.
Steel structure load-bearing:
The frame load-bearing structure is a load-bearing system composed of a horizontal frame and a longitudinal connecting member, and the wall only serves as an enclosure. It is suitable for large spans, high plants, and large crane loads. The load-bearing framework is made of steel plate or hot-rolled steel through cutting and welding.
