This product is made of high-strength resin as the base material, with glass fiber and calcium-based fillers as the reinforcing materials. It is formed through one-time high-temperature molding. It is an environmentally friendly composite material manhole cover with no recycling value. The product has high overall strength, light weight, no insulation or magnetism, resistance to acid and alkali corrosion, and a long service life, meeting the requirements of relevant standards.
The product adopts a socket-type sealed structure. The manhole cover and the manhole ring fit precisely, effectively solving problems such as abnormal sounds, displacement, and theft of traditional manhole covers. The surface has anti-slip texture, good sealing performance, and can prevent rainwater and debris from entering the manhole.
The product is insulated and flame-retardant, with no recycling value. This fundamentally prevents theft and is particularly suitable for light-load areas such as sidewalks, green belts, residential areas, parks, factory areas, weak current wells, communication wells, and gas wells. The bearing grade meets the requirements of A15, B125, and C250. Installation is convenient, maintenance is simple, and it is environmentally friendly.
