Compared with the traditional concrete structure, the multi-storey steel structure building has the advantages of fast construction speed, light weight, good seismic performance and environmental protection.

Features: Frame-support structure, composite floor with pressed steel plate, and glass curtain wall facade.
Advantages: Short construction period, high space utilization, modern appearance.

Features: Frame-shear wall structure with light partition walls and reinforced concrete flooring.
Advantages: Excellent seismic performance and flexible spatial layout.

Realizes large-span designs to reduce columns, providing spacious commercial space with modern glass curtain walls.
