Supplier's note

  1. Key Technical Breakthroughs:

    • ASTM Compliance: Ensures global project compatibility.
    • ±1% Tolerance: Enables seamless integration into precision engineering.
    • Multi-Service Processing: Reduces outsourcing costs with in-house bending/welding.
  2. Optimal Version Selection:

    • Base Model: Ideal for standard construction (e.g., light shelving) where cost-efficiency is prioritized.
    • Advanced Model: Suited for medium-scale projects requiring welding or decoiling (e.g., machinery frames).
    • Pro Model: Recommended for heavy-duty applications (e.g., offshore platforms) needing tripled corrosion resistance and CNC precision. With its zinc-plated surface, the Pro Model safely handles marine environments while maintaining structural integrity.
