Composite Manhole Cover

High strength anti corrosion composite manhole cover with heavy duty load bearing capacity for industrial sewage and wastewater treatment applications.

Anti corrosion EN124 lightweight composite manhole cover combining high strength with corrosion proof design for sewage and drainage systems.

EN124 certified lightweight composite manhole cover with reduced mass design for municipal drainage systems and easy on-site handling.

Designed for heavy-traffic highways, industrial zones, and logistics hubs where strength-to-weight ratio is critical, this FRP composite manhole cover combines carbon fiber reinforcement with advanced resin matrix technology. At approximately 1/3 the weight of cast iron equivalents, it dramatically reduces on-site handling costs, installation time, and workplace injury risk—without compromising load-bearing performance. Tested to EN124-1:2015 D400 standards, it withstands

Engineered specifically for municipal sewer and drainage infrastructure, this composite manhole cover delivers exceptional waterproof sealing performance in wet and corrosive underground environments. Manufactured from high-grade BMC/SMC composite materials, it provides a non-porous, watertight barrier that prevents groundwater infiltration and sewage leakage—critical for urban wastewater management systems. The cover meets EN124-1:2015 standards and is available in Square
