Description
High Strength and Fast Delivery Prefabricated Steel Structure Lightweight Construction and High Spans for Warehouse

Our high-strength prefabricated steel structure warehouses deliver a comprehensive one-stop solution, characterized by fast delivery timelines and expert installation guidance. This building system comprises two core components: an internal support framework and external enclosure systems.

The steel structure adopts a robust portal frame design, integrating steel columns, load-bearing beams, and reinforced bracing. When combined with the external enclosure, this configuration forms a fully enclosed building envelope engineered to withstand severe weather conditions—including strong winds, heavy rainfall, and snow loads—ensuring long-term structural stability.

All metal components undergo precision fabrication in our specialized workshop, where they are cut, welded, drilled, and finished with protective coatings before transportation to the site. On-site assembly is streamlined through bolted connections, enabling convenient, labor-saving installation with significantly reduced construction time. The steel frame’s performance relies on five key structural elements working in synergy: tension members, compression members, bending members, combined-stress members, and purpose-engineered connections.
