Supplier's note

  1. Technical Breakthroughs:

    • Enhanced Galvanization: The Pro Model’s triple-layer coating (2,000-hour salt spray resistance) enables safe use in coastal or chemical plants.
    • Precision Tolerance: The ±2% tolerance in Pro Models ensures seamless integration with high-precision machinery.
    • ERW Welding Strength: Uniform weld seams eliminate weak points, supporting heavy loads in bridge or crane frameworks.

  2. Optimal Version Selection:

    • Base Model: Ideal for general construction (e.g., scaffolding) where cost-efficiency is prioritized.
    • Advanced Model: Suitable for industrial machinery or outdoor furniture requiring moderate corrosion resistance and thicker walls.
    • Pro Model: Recommended for extreme environments (e.g., offshore platforms) or precision engineering projects demanding ultra-high durability and accuracy.

*Pro Model’s corrosion resistance exceeds industry benchmarks by 300%.
