Q355B Custom Steel Structure Factory Building Prefabricated Industrial Storage Building
Prefabricated steel structure factory buildings provide innovative construction solutions with economical pricing, convenient transportation, and quick installation.
These structures typically consist of:
- H steel columns and beams
- Purlins (roof and wall)
- Steel roof and wall sheets
- Rolling doors and windows
Main structural components are secured with high-strength bolts, enabling faster assembly than traditional concrete construction. The lightweight steel sheets or sandwich panels further reduce installation time.
Main components of our prefabricated steel factory buildings:
- H steel column and beam
- C or Z section roof/wall purlins
- Round tube steel tie bars
- Round steel bracing
- Color steel sheet roofing/walls
- Sandwich panel sliding doors
- PVC windows
