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.
