Supplier's note

  1. Three Technical Breakthroughs:

    • Sharp 90° Corners: Precision-machined edges ensure seamless alignment in curtain wall systems.
    • Thick-Wall Design: The Pro Model’s 5.4mm walls exceed industry standards by 35%, enabling use in earthquake-resistant structures.
    • Dual-Layer Galvanization: The Pro Model’s coating provides 2x corrosion resistance compared to standard galvanized tubes.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard curtain walls or indoor frameworks requiring cost-effective solutions.
    • Advanced Model: Suitable for outdoor projects needing enhanced corrosion resistance (e.g., coastal buildings).
    • Pro Model: Best for heavy industrial applications (e.g., bridges, offshore platforms) where extreme load and corrosion resistance are critical.

With the Pro Model’s 5.4mm thick walls, you can construct supports capable of withstanding 30% higher loads than traditional tubes. Pair its dual-layer galvanization with cold-rolled finishes to achieve both strength and smooth aesthetics for high-end architectural projects.
