Supplier's note

  1. Technical Breakthroughs:

    • OSB3 Fire Rating: Triple the flame spread resistance of standard OSB, enabling safe use in high-risk zones.
    • MDI Adhesive: 20% stronger bond than urea-formaldehyde, ensuring moisture resistance in humid climates.
    • 3D Strand Layers: Reduces warping by 40% compared to single-layer plywood.

  2. Version Selection Guide:

    • Base Model: Ideal for standard residential builds (apartments, indoor furniture) where cost-efficiency is key.
    • Advanced Model: Choose for commercial spaces (e.g., villas) needing enhanced durability and wider thickness options.
    • Pro Model: Best for industrial or extreme environments (e.g., coastal farms) requiring OSB4 fire safety and ultra-heavy loads.

Pro’s OSB4 rating allows use in high-traffic commercial areas, while its 800 kg/m² capacity outperforms industry benchmarks by 30%. Pair with Ultra MDI Pro for zero water absorption in marine applications.
