Supplier's note

  1. Three Technical Breakthroughs:

    • FRP Material: 50% lighter than cast iron, reducing installation labor costs.
    • D400 Load Class: Exceeds EN124 standards for heavy-duty use.
    • UV-Enhanced Coating: Prevents surface degradation in extreme climates.

  2. Optimal Version Selection:

    • Base Model: Ideal for residential areas or light commercial use where standard load and temperature ranges suffice.
    • Advanced Model: Perfect for industrial zones requiring UV resistance and moderate load handling.
    • Pro Model: Designed for extreme environments (e.g., Arctic pipelines or tropical ports) with ultra-wide temperature tolerance and D600 load capacity.

With the Pro Model’s triple-layer FRP, you can ensure structural integrity in corrosive wastewater systems. Pair its D600 load rating with UV resistance to create a maintenance-free solution for decades of use.
