This high-strength prefabricated steel structure warehouse offers a comprehensive solution with rapid delivery and expert installation guidance. The structure comprises both internal support and external enclosure components.
The steel frame features a portal design with robust steel columns, beams, and bracing. Together with the external enclosure, this design creates a fully enclosed building capable of withstanding severe weather conditions, including strong winds, heavy rainfall, and snow loads.
All metal components are meticulously processed in our workshop—cut, welded, drilled, and painted—before transportation to the construction site. Each component is bolted together, allowing for convenient and efficient installation, which significantly reduces labor requirements.
The steel frame consists of five main structural elements:
- Tension Members
- Compression Members
- Bending Members
- Combined Stress Members
- Connections
These components work together to ensure optimal load-bearing capacity and stability.
- Lightweight Construction: High strength with large spans and reduced foundation pressure.
- Rapid Assembly: Shorter construction period compared to concrete buildings, facilitated by simple on-site assembly.
- Cost Efficiency: Investment costs are 20-30% lower than those of traditional buildings.
- Durability: High fireproof performance and exceptional corrosion resistance enhance longevity.
- Sustainability: Buildings can be easily disassembled, relocated, and recycled, minimizing environmental impact.
