Composite Resin Manhole Cover

Park drainage systems, chemical park channels, and utility areas often have special requirements beyond normal drainage performance. Some locations require electrical insulation for safety. Some unattended areas need solutions with lower theft risks. Other projects require lightweight products for easier installation.

Traditional ductile iron covers may not meet all these application needs. Our Dingjian composite resin manhole cover provides an alternative solution. The item number is 50025020. The product uses composite material and provides a 120 kN load capacity with a B125 rating. It offers advantages in insulation, weight reduction, and corrosion resistance compared with traditional metal covers.

Composite materials have limited recycling value compared with metal products. This makes composite resin manhole covers less attractive for theft in open areas such as parks and public landscapes.

The lightweight structure also improves installation efficiency. The weight is approximately one-third of a similar-sized iron cover, allowing two workers to carry and install the product easily. No heavy lifting equipment is required, which helps reduce labor costs and installation time.

Composite materials provide excellent electrical insulation properties, making them suitable for utility applications. Power pits, communication pits, and cable access points often contain complex electrical systems where additional safety considerations are required.

Composite resin manhole covers help reduce electrical safety risks because they do not conduct current like metal covers. They are suitable for applications such as substation areas, telecom base stations, and utility inspection pits.

The composite structure also provides better resistance to acid and alkaline environments compared with traditional iron products, making it suitable for chemical parks and wastewater treatment facilities.
