Supplier's note

  1. Technical Breakthroughs:

    • Galvanized Steel Construction: Enhances corrosion resistance for outdoor HVAC applications.
    • Three-Roller Precision: Ensures tight tolerances for duct curves, reducing material waste.
    • Manual Adjustable Pressure: Allows operators to adapt to varying sheet thicknesses on-site.

  2. Version Selection Guide:

    • Base Model: Ideal for small workshops or contractors needing cost-effective manual control.
    • Advanced Model: Suitable for medium-scale operations requiring semi-automated processing of thicker sheets (e.g., industrial duct systems).
    • Pro Model: Best for high-volume production environments demanding full automation and heavy-duty capacity (e.g., large-scale construction projects).

With the Pro Model’s 1.5mm thickness capability, you can handle thicker galvanized sheets for structural applications, while its 6.5m/min speed outperforms traditional manual rollers by 30%. Pair this with its 3-year warranty for long-term reliability in harsh environments.
