Product Description

1. Introduction

A steel structure industrial building, commonly referred to as a space frame workshop, is a prefabricated, high-strength construction designed for manufacturing plants, warehouses, logistics centers, and large-span facilities. These structures are characterized by their lightweight yet durable steel framework, rapid construction, and adaptability to various industrial needs. This report provides a detailed technical description of such buildings, covering structural design, material specifications, load considerations, enclosure systems, and auxiliary installations.

 

2. Structural System

2.1 Primary Steel Frame

The main load-bearing structure consists of:

• Columns & Beams: Fabricated from hot-rolled or welded H-sections (e.g., Q355B steel, equivalent to ASTM A572 Gr.50).

• Rigid Frames: Typically single-span (20m~40m) or multi-span (24m+24m) configurations with eave heights ranging from 6m to 15m.

• Connections: High-strength bolted (Grade 10.9) and welded joints for stability.

2.2 Secondary Structural Components

• Purlins & Girts: Made of cold-formed C/Z-sections (galvanized, 2.0~3.0mm thickness) spaced at 1.5m intervals.

• Bracing Systems:

  • Horizontal bracing (roof & wall) using angle steel or round bars.

  • Vertical bracing (X-type or K-type) for seismic and wind resistance.

2.3 Crane Systems (If Applicable)

• Overhead Cranes (5t~50t capacity) supported by crane runway beams (HN600×200×11×17).

• Deflection limits: ≤ L/800 (to ensure smooth operation).

 

3. Building Envelope & Cladding

3.1 Roofing System

• Material Options:

  • Sandwich Panels (50~100mm PU/Rockwool core, 0.5mm steel skin).

  • Corrugated Sheets (0.4~0.7mm Galvalume, AZ150 coating).

• Slope: 1:10 to 1:12 for drainage.

• Accessories: Ridge caps, gutters, and natural ventilators.

3.2 Wall Cladding

• Options:

  • Single Skin (Corrugated steel, 0.5mm).

  • Insulated Panels (Same as roofing).

• Doors: Roll-up doors (4m×5m) or sliding doors.

• Windows: Polycarbonate or aluminum-framed glazing.

 

4. Load Considerations

4.1 Dead Load

• Roof: 0.3 kN/m² (including purlins & cladding).

• Walls: 0.2 kN/m².

4.2 Live Load

• Roof: 0.5 kN/m² (maintenance load).

• Floor: 5~20 kN/m² (depending on usage).

4.3 Wind & Snow Load

• Wind Pressure: 0.5~0.8 kN/m² (Zone III/IV).

• Snow Load: 0.7~1.2 kN/m² (Northern regions).

4.4 Seismic Load

• Design Standard: GB 50011 / Eurocode 8.

• Peak Ground Acceleration (PGA): 0.1g~0.3g (Zone 7~8).

 

5. Corrosion & Fire Protection

5.1 Corrosion Resistance

• Galvanizing: 80μm (secondary members).

• Paint Coating: Epoxy primer + Polyurethane topcoat.

5.2 Fireproofing

• Fire Rating: 1~2 hours (columns/beams).

• Intumescent Paint: 2.0mm thickness.

 

6. Foundation & Flooring

6.1 Foundation Types

• Isolated Footings (for stable soil).

• Pile Foundations (soft soil conditions).

6.2 Floor Slab

• Concrete Grade: C25~C30.

• Reinforcement: Φ12@200mm (two-way mesh).

 

7. Mechanical & Electrical Systems

7.1 Ventilation

• Ridge Ventilators: 1m width per 6m span.

• Wall Exhaust Fans: 800mm diameter.

7.2 Lighting

• LED High Bay Lights: 150~200W @ 8m height.

7.3 Fire Safety

• Sprinklers / Hydrants (if required).

 

8. Advantages of Steel Space Frame Workshops

 Fast Construction (30~50% quicker than concrete).
 High Strength-to-Weight Ratio.
 Customizable Spans & Heights.
 Eco-Friendly (Recyclable Steel).

 

9. Applications

• Factories (Automotive, Textile, Food Processing).

• Warehouses & Logistics Centers.

• Aircraft Hangars & Sports Arenas.

 

10. Conclusion

A steel space frame workshop is a cost-effective, durable, and flexible solution for modern industrial needs. Its modular design, high load capacity, and quick assembly make it ideal for large-scale manufacturing and storage facilities.
