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.

2. Structural System

Primary Steel Frame: Consists of columns and beams fabricated from hot-rolled or welded H-sections (e.g., Q355B steel). Typically configured as single-span (20m~40m) or multi-span (24m+24m) with eave heights from 6m to 15m.

Secondary Components: Includes Purlins & Girts made of cold-formed C/Z-sections and robust bracing systems (Horizontal and Vertical) for seismic and wind resistance.

Crane Systems: Supports overhead cranes (5t~50t capacity) with specialized runway beams designed for minimal deflection.

3. Building Envelope & Cladding

• Roofing: Sandwich Panels (PU/Rockwool core) or Corrugated Sheets with Galvalume coating. Designed with a 1:10 to 1:12 slope for efficient drainage.
• Wall Cladding: Single skin or insulated panels with options for roll-up or sliding doors and polycarbonate windows.

4. Technical Considerations

• Load Capacity: Engineered for dead loads (roof/walls), live maintenance loads, and heavy industrial floor loads (up to 20 kN/m²).
• Weather Resistance: Designed for wind pressures of 0.5~0.8 kN/m² and heavy snow loads in northern regions.
• Protection: Includes corrosion resistance (galvanizing & epoxy coating) and fireproofing (1~2 hours rating with intumescent paint).

5. Key Advantages

Fast Construction: 30~50% quicker than traditional concrete methods. High strength-to-weight ratio allows for customizable spans and heights while remaining eco-friendly and recyclable.
