With the rapid development of urban and rural construction, the demand for new residential areas and related road supporting facilities, such as composite manhole covers in Chongqing, has increased sharply. However, the high cost of traditional cast iron manhole covers, serious theft, pedestrian injuries, and vehicle damage have always been a problem for construction departments.

The FRP composite manhole cover is mainly made of unsaturated resin as the main chemical raw material and a variety of materials. After forming, it has not only high strength, beautiful appearance, but also good electrical insulation performance, waterproof, aging resistant, acid and alkali resistant, wear-resistant, high strength, and is not afraid of the sun and rain, impact resistant, anti-static, anti-theft and other characteristics. It is an ideal substitute for cast iron manhole covers.
