ACRS STANDARD Steel Structure School

Introduce

ACRS (Australian Cold-Formed Steel Structures Standard) compliant steel structure production follows a systematic and standardized process encompassing design, material preparation, manufacturing, quality control, and transportation to ensure final products meet Australian cold-formed steel performance and safety requirements. The production workflow includes the following key stages:

1. Design and Engineering Preparation: Structural design is conducted based on architectural requirements, calculating loads (including dead loads, live loads, wind loads, seismic loads, etc.) in compliance with AS/NZS 4600 standards to meet ACRS specifications. Professional software (such as AutoCAD, Revit, or Tekla Structures) is employed for 3D modeling and structural analysis to ensure design integrity.

2. Material Selection and Preprocessing: Steel materials conforming to AS 1397 or AS/NZS 1163 standards are selected to guarantee strength and workability. The steel undergoes precision cutting (via laser cutting, plasma cutting, or CNC shearing) followed by punching and slotting to accommodate connection requirements, with all hole position tolerances controlled within ±1mm.

3. Cold-Forming Process: Steel sheets are shaped into C-sections, Z-sections, U-sections, and other profiles through roll forming or press brake operations, with strict control of springback to ensure dimensional accuracy per design specifications.

4. Welding and Assembly (where applicable): Components requiring welding undergo MIG/TIG or resistance welding by AS/NZS 1554-certified welders. Post-weld non-destructive testing (e.g., ultrasonic or X-ray inspection) verifies weld quality. Critical connection joints undergo trial assembly to validate bolt hole alignment and fit-up accuracy, preventing on-site installation issues.

5. Surface Treatment and Corrosion Protection: Components receive hot-dip galvanizing per AS/NZS 4680 standards (typically ≥80μm zinc coating, Z275 grade) for enhanced durability. Additional powder coating or epoxy coating may be applied for structures in harsh environments.

6. Quality Inspection and Testing: Rigorous inspections occur throughout production, including dimensional verification (ensuring ACRS-compliant tolerances), mechanical property testing (tensile tests, hardness tests), and anti-corrosion coating thickness measurement using specialized gauges.

7. Packaging and Transportation: Approved components are packaged with anti-corrosion measures (e.g., VCI film or desiccants) to prevent moisture damage during transit. Customized racks secure components to prevent deformation, ensuring ready-to-install condition upon arrival at construction sites.

The entire production process strictly adheres to ACRS and relevant Australian standards, guaranteeing steel structures with high strength-to-weight ratio, superior corrosion resistance, and excellent seismic performance - making them ideal for residential, commercial, and industrial applications.
