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.
Construction Features
- Lightweight construction with high strength, large spans, and
reduced foundation pressure
- Shorter construction period compared to concrete buildings with
simple on-site assembly
- 20-30% lower investment cost than traditional buildings
- High fireproof performance and corrosion resistance
- Buildings can be disassembled, moved easily, and recycled with no
pollution
