BASIC INFO
Resin manhole covers are a type of manhole cover made from composite materials, often incorporating resins such as fiberglass reinforced polyester (FRP) or other polymer-based materials. Traditional manhole covers are typically made of materials like cast iron or concrete, but resin manhole covers offer several advantages.
