Custom Q235B Galvanized Steel Structure Construction Shed
Custom Q235B Galvanized Steel Structure Construction Shed for Warehouse Workshop or Hall Application
Construction Features
  • Lightweight construction with high strength, large spans, and reduced foundation pressure
  • Shorter construction period compared to concrete buildings, facilitated by simple on-site assembly
  • Investment costs are 20-30% lower than those of traditional buildings
  • High fireproof performance and excellent corrosion resistance
  • Buildings can be easily disassembled, relocated, and recycled, generating no pollution
The high-strength prefabricated steel structure warehouse offers a comprehensive solution with fast delivery and experienced installation guidance. This building structure consists of both internal support and external enclosure components.
The steel frame features a portal design, incorporating steel columns, beams, and bracing. This design, combined with the external enclosure, creates an enclosed building capable of withstanding severe weather conditions, including strong winds, heavy 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 and quick installation, saving on labor costs. The steel frame comprises five main structural components: tension members, compression members, bending members, combined stress members, and their connections.
