Product Description

Product Description

Q355B / ASTM A572 Gr.50

 

Description: The steel structure building is constructed using high-strength steel, providing exceptional load-bearing capacity. This makes it ideal for large-span and high-rise buildings, offering a reliable and durable construction solution. The lightweight nature of the steel buildings allows for fast construction, making it suitable for industrial plant structures, steel bridge construction, steel stadium structures, and more. With a focus on steel welding and bolting, these structures ensure a secure and efficient building process. Invest in our steel structure building for a versatile, cost-effective, and long-lasting solution for your construction needs.
 

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.
