Factory Direct Prefabricated Multi-story Steel Structure Factory Building
Our steel structure factory buildings feature rapid assembly and factory-direct prefabrication for efficient industrial construction solutions.
Product Overview
The main load-bearing frame is constructed from steel columns, steel beams, and steel trusses connected by welding or high-strength bolts. Components are primarily prefabricated in factories and assembled on-site, representing the mainstream form of modern industrial factory buildings.
Core Components
- Load-bearing Frame: Steel columns (H-shaped steel columns/box columns), steel beams (H-shaped steel beams/truss beams)
- Roofing System: Purlins, roof panels (color steel plates/sandwich panels), skylights, gutters
- Enclosure System: Wall purlins, wall panels, insulation layer, doors and windows
- Support System: Inter-column bracing, roof horizontal bracing for wind and earthquake resistance
- Foundation System: Reinforced concrete independent foundations/pile foundations with embedded parts
