Lightweight Prefab Small Buildings Industrial Commercial Easy Transport

Prefabricated steel structure buildings offer a modern, quick-installed alternative to traditional concrete construction. These structures primarily consist of steel columns, beams, trusses, bracing, purlins, U channels, angle steel, and steel plates, connected through welding, bolts, and rivets to form a complete frame.

The steel frame typically comprises vertical columns and horizontal beams bolted or welded together. Columns transfer compressive loads to form the building skeleton, while beams resist lateral loads. All components are precision-manufactured in factory conditions with tolerances under 2mm for optimal structural integrity.

Main components of our steel structure prefabricated buildings:

• Primary Framing: H-section steel columns and beams (hot rolled or welded) with anti-rust surface treatments
• Secondary Framing: Purlin and tie bar systems fixed with common bolts
• Bracing: Round steel knee bracing for enhanced structural stability
• Cladding: Weather-resistant color-coated corrugated steel sheets or sandwich panels
• Windows/Doors: Plastic steel/aluminum windows with sliding/folding door options
• Optional Features: Gutters, downpipes, transparent sheets, ventilators, and bridge cranes

• Primary Framing: Box beam column, cross steel column, H-shaped steel column, steel beam
• Secondary Framing: Galvanized Z and C sections purlin
• Roof/Wall Panels: Steel sheet and insulated sandwich panels (EPS, fiberglass wool, PU)
• Structural Subsystems: Divider, gutter, awning, partition wall
• Service Life: 50-70 years
• Materials Grade: Q235B, Q355B or custom specifications
• Connection Methods: Intensive bolt, ordinary bolt systems
