Structural Steel Fabrication Process - Precision Engineering for Superior Quality

At LiYou Steel, we specialize in delivering high-quality structural steel fabrication for industrial, commercial, and infrastructure projects worldwide. Our ISO 9001 and CE-certified fabrication process ensures precision, durability, and cost-efficiency in every steel component we produce.

Our 8-Step Structural Steel Fabrication Process

  1. Design & Engineering

    • 3D modeling using Tekla, AutoCAD, and Revit

    • Load calculations and stress analysis for optimal performance

    • BIM coordination to prevent clashes in construction

  2. Material Selection & Testing

    • High-grade steel (Q235B, Q345B, ASTM A36)

    • Ultrasonic testing (UT) and mill certification for quality assurance

    • Shot blasting (Sa 2.5 standard) for rust removal

  3. Cutting & Drilling

    • CNC plasma cutting (±1mm accuracy)

    • High-speed drilling machines for bolt holes

    • Bevel cutting for perfect weld joints

  4. Forming & Bending

    • Hydraulic press brakes (up to 500-ton capacity)

    • Roll bending for curved structural members

    • Cold-forming for light gauge components

  5. Welding & Assembly

    • Submerged Arc Welding (SAW) for thick plates

    • Gas Metal Arc Welding (GMAW) for precision joints

    • 100% weld inspection (X-ray/UT testing available)

  6. Surface Treatment

    • Hot-dip galvanizing (up to 120μm coating)

    • Epoxy/polyurethane painting (custom RAL colors)

    • Fireproof coatings (up to 2-hour fire rating)

  7. Quality Control

    • Dimensional checks with laser measuring tools

    • Load testing on critical connections

    • Third-party inspection (SGS/TÜV available)

  8. Packaging & Shipping

    • Weatherproof wrapping for ocean transport

    • Custom crating for delicate components

    • Real-time GPS tracking for all shipments
