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
