Product Description

Grp Round Manhole Cover China Suppliers Long Time Sevice Frp Manhole Covers With Frame

FRP Manhole Cover

FRP manhole covers use glass fiber and its products (glass cloth, tape, felt, yarn, etc.) as reinforcing materials and synthetic resin as matrix materials. They are mainly composed of unsaturated polyester resin, fillers, initiators, thickeners, low shrinkage additives, film-forming agents, pigments, and reinforcing materials. FRP manhole covers are new manhole covers developed to solve the defects of steel and iron manhole covers, such as easy rust and theft, too heavy, and easy to crack, and to improve their use functions and economic and social benefits.

The manhole cover is reinforced with mesh steel bars, and the key force-bearing parts are specially strengthened. When an inevitable external force impact occurs, the pressure can be quickly dispersed to ensure the safety of people and vehicles. It does not contain metal, and the steel bar skeleton of stone plastic manhole covers and concrete manhole covers is less than 1/10 of the total weight of the manhole cover. Moreover, due to the extremely high strength of the manhole cover, it is extremely difficult to remove this small amount of steel bars from the manhole cover.

FRP manhole covers can be colored at will, and are easy to install, maintain, and identify. Since they have no recycling value, they completely solve the problem of anti-theft. They have strong anti-theft performance because resin composite manhole covers are made of unsaturated resin, glass fiber, and other materials and steel skeletons through a special production process. They are formed in one step by high-temperature grinding and pressing. The materials have no recycling value, and it is very difficult to remove the steel bars (the cost of removing the steel bars exceeds the value of the steel bars). Therefore, they have the function of active anti-theft.
