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

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). Rigid Frames are typically single-span (20m~40m) or multi-span (24m+24m) configurations.

2.2 Secondary Structural Components: Includes Purlins & Girts made of cold-formed C/Z-sections and Bracing Systems (Horizontal and Vertical) for seismic and wind resistance.

2.3 Crane Systems: Overhead Cranes (5t~50t capacity) can be supported by crane runway beams with strict deflection limits.

3. Building Envelope & Cladding

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

4. Load & Protection

Designed to withstand specific Dead Loads, Live Loads (maintenance), Wind Pressure (0.5~0.8 kN/m²), and Snow Loads. The structure includes corrosion resistance via galvanizing or epoxy paint and fireproofing with intumescent coatings for 1-2 hours of rating.

5. Foundation & Flooring

Utilizes Isolated Footings for stable soil or Pile Foundations for soft conditions. Floor slabs typically use C25~C30 grade concrete with reinforcement mesh.

• Fast Construction: 30~50% quicker than traditional concrete methods.
• High Strength: Exceptional strength-to-weight ratio for large spans.
• Eco-Friendly: 100% recyclable steel materials.
• Versatile: Ideal for automotive, textile, logistics centers, and sports arenas.
