The high-strength prefabricated steel structure warehouse provides a comprehensive one-stop solution with fast delivery and experienced installation guidance. This building system is composed of two main parts: internal support framework and external enclosure components.
The steel frame features a portal steel frame structure, including steel columns, beams, and bracing. Together with the external enclosure, it forms a fully enclosed building capable of withstanding severe weather conditions such as strong winds, heavy rain, and snow.
All metal components are cut, welded, drilled, and painted in our workshop before transportation to the construction site. Each component is bolted on-site for quick and labor-saving installation.
The steel frame comprises five key structural elements:
- Tension members
- Compression members
- Bending members
- Combined-stress members
- Connections
- 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
