Supplier's note

  1. Technical Breakthroughs:

    • The 5-gear system reduces friction by 30% compared to 3-gear hinges, enabling smoother operation.
    • The flared mounting base increases surface contact by 25%, enhancing stability in uneven surfaces.
    • Dual-finishing layers (primer + epoxy) extend lifespan by 50% in humid environments.

  2. Optimal Version Selection:

    • Basic Model: Ideal for standard sofa beds (≤150kg load). Its black/white finishes suit modern minimalist designs.
    • Premium Model: Recommended for commercial use (e.g., hotels) where frequent folding and corrosion resistance are critical.
    • Pro Model: Best for heavy-duty applications (e.g., industrial furniture) requiring extreme load capacity and custom finishes.

With the Pro Model’s heat-treated alloy gears, you can ensure decades of use even in high-traffic settings. Pair its corrosion-resistant coating with the flared base to guarantee stability in coastal or humid regions.
