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.
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.
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.
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.
Overhead Cranes (5t~50t capacity) supported by crane runway beams (HN600×200×11×17).
Deflection limits: ≤ L/800 (to ensure smooth operation).
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.
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.
Roof: 0.3 kN/m² (including purlins & cladding).
Walls: 0.2 kN/m².
Roof: 0.5 kN/m² (maintenance load).
Floor: 5~20 kN/m² (depending on usage).
Wind Pressure: 0.5~0.8 kN/m² (Zone III/IV).
Snow Load: 0.7~1.2 kN/m² (Northern regions).
Design Standard: GB 50011 / Eurocode 8.
Peak Ground Acceleration (PGA): 0.1g~0.3g (Zone 7~8).
Galvanizing: 80μm (secondary members).
Paint Coating: Epoxy primer + Polyurethane topcoat.
Fire Rating: 1~2 hours (columns/beams).
Intumescent Paint: 2.0mm thickness.
Isolated Footings (for stable soil).
Pile Foundations (soft soil conditions).
Concrete Grade: C25~C30.
Reinforcement: Φ12@200mm (two-way mesh).
Ridge Ventilators: 1m width per 6m span.
Wall Exhaust Fans: 800mm diameter.
LED High Bay Lights: 150~200W @ 8m height.
Sprinklers / Hydrants (if required).
Fast Construction (30~50% quicker than concrete).
High Strength-to-Weight Ratio.
Customizable Spans & Heights.
Eco-Friendly (Recyclable Steel).
Factories (Automotive, Textile, Food Processing).
Warehouses & Logistics Centers.
Aircraft Hangars & Sports Arenas.
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.
