Steel Structure Description
Our high-strength prefabricated steel structure warehouses offer a
one-stop solution, featuring prompt delivery and professional
installation guidance. The building structure comprises internal
support systems and external enclosure components, with the steel
frame adopting a portal steel frame design that includes steel
columns, beams, and bracing. This portal steel frame, in
conjunction with the external enclosure structure, forms a fully
enclosed building capable of withstanding harsh weather conditions
such as strong winds, heavy rain, and heavy snow.
All metal components undergo precise cutting, welding, drilling,
and painting processes in our workshop prior to transportation to
the construction site. Each component is secured using bolts,
enabling convenient and efficient installation while reducing labor
costs. The steel frame is composed of five key structural elements:
tension members, compression members, bending members, combined
stress members, and their respective 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
