International Standard Prefabricated Steel Structure Building with Plastic Steel Window and Excellent Seismic Performance
Prefabricated steel structure buildings represent innovative construction solutions offering economical pricing, convenient transportation, and quick installation.
These structures typically consist of:
- H steel columns and beams
- Purlins
- Roof and wall sheets
- Rolling doors and windows
Main structural components are secured with high-strength bolts, while purlins are fixed with 4.8S bolts, enabling faster assembly than traditional concrete construction. The lightweight steel sheet or sandwich panel roofing and walls further reduce construction time.
Prefabricated steel buildings comprise three essential interconnected components:
- Primary members (columns, beams, bracing)
- Secondary members (Z/C purlins, girts, eave struts)
- Roof and wall sheeting
- Additional building components
All primary and secondary members are precision-fabricated in our factory before shipment.
