Steel Frame Commercial Prefabricated Multi-Storey Building with Q235/Q355 Steel and 50-100mm Insulated Panels
Our steel frame commercial prefabricated multi-storey buildings utilize advanced bolt connection systems for superior structural integrity and construction efficiency. The design ensures adequate strength and stiffness to resist vertical gravity loads and horizontal wind loads.
The most common structural forms include composite systems and Slimdek systems, providing flexibility for various building requirements.
Multiple structural forms ensure lateral stability, including shear walls, lattice frames, and rigid frames, with advanced systems available for taller structures.
