Resin manhole covers are used on the roads, which have the characteristics of insulation, no noise, no recycling value and natural anti-theft. They are irreplaceable for cast iron manhole covers. The resin manhole cover is made by a unique molding process, which makes the city look like a new one. The service life is basically 20-50 years. The resin composite manhole cover molded by high temperature has light weight, high strength, excellent fatigue resistance, and damage safety. , Simple molding, low rolling noise, good chemical corrosion resistance, good acid and alkali resistance and beautiful appearance, etc., and the pollutants in the wastewater are further reduced.


Now on the market, the manhole covers produced by various composite manhole cover manufacturers use different materials, but several characteristics are similar:

1. Strong anti-theft performance: composite manhole cover manufacturers generally use unsaturated resin, glass fiber and other materials to compound them through a special production process. After high temperature molding, the product has no recycling value.

2. Service life: Through the use of high-performance resin, glass fiber and special production process formula, the penetration of the composite manhole cover in the glass fiber is ensured, and the bonding force between the two is greatly enhanced, so that the material will not be affected by the cyclic load. Internal damage occurs, thereby ensuring the service life of the product and the same advantages of other resin composite manhole covers, effectively eliminating the disadvantages of poor adhesion.

3. High temperature/low temperature resistance, good insulation performance, strong corrosion resistance: the product is corrosion resistant, non-toxic and harmless. No metal additives. It can be used in complex, changeable, harsh and demanding places. It has obvious acid and alkali resistance, corrosion resistance, anti-aging and many other indicators that have reached product quality specifications.

4. 4. Beautiful and practical, high-grade: According to the needs of high-end customers, a personalized design with complex LOGO and multiple colors on the same manhole cover can be made to make the pattern delicate, bright and distinct. And according to customer needs, it can be made into a variety of imitation stone appearances and colors that are the same as various stone pavements.

5. Strong load-bearing capacity: The bottom adopts a special design structure, and the continuous reinforcing fiber yarns used are made from the material to ensure that the fiber yarns and glass fiber cloth are integrated, so that the product has a certain load-bearing capacity.

6. Environmental protection, non-slip, low noise: The manhole cover will not slip after the car is rolled, and there will be no back-ear noise and pollution.
