Q355 Carbon Steel Prefabricated Building Fabrication For Industrial And Commercial
Steel structure prefabricated buildings are modern quick-install structures that offer advantages over traditional concrete or wood buildings. The framework consists of steel columns, beams, trusses, bracing, purlins, U channels, angle steel and steel plates connected through welding, bolts or rivets.
The steel frame typically features vertical columns and horizontal beams joined by bolting or welding. Columns transfer compressive loads while beams resist lateral loads. All components are precision-manufactured in our factory with tolerances under 2mm for perfect fit during assembly.
Our prefabricated steel buildings include these key components:
| Component | Part | Material Specification |
|---|---|---|
| Main Steel Frame | Column | Q235, Q355 Welded H Section Steel |
| Main Steel Frame | Beam | Q235, Q355 Welded H Section Steel |
| Secondary Frame | Purlin | Q235 C and Z purlin |
| Secondary Frame | Knee Brace | Q235 Angle Steel |
| Maintenance System | Roof Panel | EPS Sandwich Panel/Giass Fiber Sandwich Panel/Rock Wool Sandwich Panel |
| Accessories | Window | Aluminium Alloy Window/PVC Window/Sandwich Panel Window |
