Our square SMC fiberglass composite manhole cover is manufactured using high-grade fiberglass, BMC/SMC resin and composite materials through high-temperature compression molding. Unlike traditional cast-iron covers, this anti-theft & anti-rust composite manhole cover eliminates theft risks and corrosion damage, greatly reducing maintenance costs for municipal and industrial projects. It is widely used in urban roads, residential areas, parking lots, drainage networks and telecommunication infrastructure, making it the ideal replacement for conventional metal manhole covers.

Engineered for heavy-duty usage, our EN124 certified square manhole cover supports graded load standards including A15, B125, C250 and D400, suitable for pedestrian areas, vehicle roads and industrial zones. The solid composite structure ensures stable performance under long-term pressure and extreme weather, with a service life far longer than traditional products.
As a non-metallic FRP BMC SMC manhole cover, it has no recycling value for thieves, completely solving the common theft problem in urban facilities. The resin-based composite material is naturally rust-proof, chemical-resistant and weather-resistant, maintaining stable appearance and performance without painting or frequent maintenance.
The precision molding process creates a tight fit between the cover and frame, reducing noise from vehicle rolling. The non-slip surface design enhances safety for pedestrians and vehicles, while the lightweight structure allows easier installation and replacement with less labor cost.
Elite square SMC fiberglass composite manhole cover fully complies with EN124-2:2015 European standards. Each product undergoes strict pressure testing, fatigue testing and weather resistance testing before shipment. Official test reports are available for project approval and bidding.
