Modular Prefab Steel Structure Industrial Building with Q355B H-Section Steel and 5-20 Ton Crane Capacity
Our modular prefab steel structure industrial buildings feature H-section steel columns and beams, C/Z purlins, and durable cladding systems. These engineered structures offer lightweight construction, rapid assembly, and exceptional cost-efficiency for industrial applications.
- Primary Framing: H-section steel columns and beams (Q355B grade)
- Secondary Framing: C/Z purlins (galvanized Q235B steel)
- Bracing System: Round steel knee bracing for enhanced stability
- Cladding Options: PPGI steel sheets or insulated sandwich panels (EPS, fiberglass, rockwool, PU)
- Accessories: Standard and high-strength bolts, gutter systems, ventilation, and overhead cranes (5-20 ton capacity)
| Component | Material Specification |
|---|---|
| Main Steel Frame | H-section steel Q355B |
| Steel Purlin | C/Z purlin, galvanized steel Q235B |
| Cladding Material | PPGI steel sheet or sandwich panel (EPS, fiberglass, rockwool, PU) |
| Accessories | Ordinary/high strength bolts, galvanized/stainless steel gutter, PVC/metal downpipes |
Our steel building systems support multiple structural configurations for diverse industrial requirements:
- Portal Frame: Simple construction with rigid beam-column connections for industrial facilities
- Frame Structure: Flexible design for commercial spaces including offices, shopping centers, and exhibition halls
- Truss Structure: Small-section tube construction for large-span factory roofs
- Grid Structure: Multi-super stable space system for stadiums and large industrial plants
- Cost-effective construction with 30-50% shorter build times
- Lightweight components for easier transportation and handling
- High durability with minimal maintenance requirements
- Customizable designs to meet specific project requirements
- Environmentally friendly construction with reduced waste generation
- Easy assembly and disassembly for flexible facility management
We provide comprehensive design support and accurate project quotations based on your specific requirements:
- Project location and local climate conditions (wind speed, snow load)
- Building dimensions and intended usage (warehouse, workshop, factory)
- Crane beam requirements and material specifications
- Window, door, and cladding preferences
Our production process ensures precision and quality at every stage:
- Material preparation and quality inspection
- Precision cutting and component shaping
- Professional welding and structural joining
- Surface treatment for corrosion resistance
- Careful packaging for secure transportation
Main steel frames are packed on steel pallets for efficient handling and container optimization. Secondary components are securely packaged in parcels, with complete structures typically fitting within 40ft HQ containers for safe international transport.
- Custom design drawings and accurate project budgeting
- Site-specific engineering recommendations
- Market updates on steel pricing and shipping costs
