The manhole covers made of fibre reinforced plastic (FRP) with high structural performance to withstand load, fatigue and wear without deterioration.

The continuous reinforcing fiber yarn used guarantees that the fiber yarn and the glass fiber cloth are integrated into one material, so that the product has sufficient bearing capacity.
