Steel Structure Description
The high strength prefabricated steel structure warehouse provides
a one-stop solution with fast delivery and experienced installation
guidance. This building structure consists of internal support and
external enclosure components.
The steel frame features a portal steel frame design including
steel columns, beams, and bracing. The portal steel frame and external enclosure structure create an enclosed building capable of withstanding severe weather
conditions including strong winds, rain, and snow.
Metal components are cut, welded, drilled, and painted in our
workshop before being transported to the construction site. Each component is fixed with bolts for convenient, quick
installation that saves labor. The steel frame consists of five main structural components:
tension members, compression members, bending members, combined
stress members, and their 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
