High security:

Anti theft: No recycling value, fundamentally solving the social problem of theft of cast iron manhole covers.

Fall prevention: The product has strong overall integrity, with a structural design that can connect the upper and lower parts. The load-bearing layer is integrated with the well seat to avoid breakage and detachment during use, ensuring high safety.

Anti slip performance: The surface is usually designed with exquisite patterns or bumps, providing excellent anti slip performance and ensuring the safety of pedestrians and vehicles.

Excellent performance:

High strength and high load-bearing capacity: Through structural design and fiber reinforcement, its load-bearing capacity can fully meet the highest level of national standards (such as D400, E600, F900), and can be used in heavy-duty areas such as airports, ports, and highways.

Corrosion resistance: It has strong corrosion resistance to chemicals such as acid, alkali, salt, sewage, and organic solvents, and is particularly suitable for high corrosion environments such as chemical parks, beaches, and sewage treatment plants. Its lifespan far exceeds that of cast iron manhole covers.

Fatigue resistance: It has good toughness and elasticity, and is not prone to fatigue fracture under repeated rolling of vehicles.

Lightweight: The weight is only 1/3 to 1/4 of the same specification cast iron manhole cover, making it easy to transport, install, and open for maintenance, greatly reducing labor intensity.

Practicality and environmental friendliness:

Low noise: There is no metallic impact sound when vehicles pass by, effectively reducing urban noise.

Aesthetic designability: adjustable color (usually dark tones), surface can be printed with place names logo、 The pattern blends better with the surrounding environment. The fit between the manhole cover and the well seat is high, and there is no seesaw phenomenon.

Insulation: non-conductive, safer to use in power wells or areas with leakage risks.

Environmental Protection: The materials are recyclable and in line with the concept of green environmental protection.
