Product Description
Prefabricated Steel Structure Industrial Buildings
Our steel structure factories are specialized industrial facilities that utilize controlled factory environments to precisely prefabricate steel materials including steel plates, sections, and pipes. The core function involves mass-producing structural components such as steel columns, beams, trusses, portal frames, and node connectors for efficient transportation and rapid on-site assembly.
Factory prefabrication delivers superior accuracy, shortened construction timelines, reduced material waste, and compliance with international quality standards compared to traditional on-site processing methods.
Main Structural Components
- H steel columns and beams for primary framework
- C or Z section roof and wall purlins
- Round tube steel tie bars for structural stability
- Round steel bracing systems
- Color steel sheet roofing and wall cladding
- Sandwich panel sliding doors
- PVC window systems

Standardized Production Process
- Drawing Detailing & Process Planning: Transform architectural designs into factory-ready details using BIM modeling; compile process cards, welding plans, and quality control protocols
- Raw Material Acceptance & Pre-treatment: Verify material certifications, conduct spectral analysis and tensile testing; perform shot blasting (Sa2.5 grade), primer application, and rust prevention
- CNC Cutting & Blanking: Precision cutting using plasma/laser/flame cutting machines with optimized nesting for maximum material utilization
- Component Processing & Assembly: CNC drilling/punching and beveling; H-beam assembly using specialized machinery for web plates and flanges
- Welding & Non-Destructive Testing: Submerged arc welding and CO₂ gas shielded welding (primarily automated); ultrasonic and radiographic flaw detection for critical welds
- Straightening & Grinding: Correct welding deformation using flange straightening machines and flame straightening; remove burrs and spatter
- Surface Coating & Corrosion Protection: Apply anti-corrosion primer, intermediate paint, and topcoat systems or hot-dip galvanizing; test paint film thickness and adhesion
- Final Inspection & Packaging: Verify dimensional accuracy and issue certificates of conformity; label with serial numbers, weight, and lifting points; implement rust-proof packaging for transport
