Composite manhole cover also caled resin manhole cover. glass fiber reinforced plastic manhole covre, polymer manhole cover, etc.
The composite manhole cover is made of unsaturated resin, glass fiber and reinforced frame by special proudction process, and molded by high temperature molding. The continuous reinforced fiber is used to ensure that the fiber and glass fiber cloth are integrated into one from the material, so that the product has sufficient bearing capacity.
Features of composite manhole cover:
1 Anti-theft function: polymer composite material is adopted and molded at high temperature. The material has no recycling value and has natural anti-theft characteristics.
2 Beautiful appearance
3 Wear resistance, high strength, acid and alkali corrosion resistance, weather resistance.
4 light weight: convenient installation and labor saving.
5 Strong impermeability: the resin composite manhole cover is made of unsaturated resin, glass fiber and reinforcement skeleton, which is compounded by special production process and molded at high temperature for one time.

6 Large bearing capacity: the bottom adopts a special bottom structure, which increases the stress area by more than ten times or even dozens of times. The continuous reinforced fiber is used to ensure the integration of fiber and glass fiber. So that the products have enough bearing capacity and reach or exceed the national standards.
The new national standard also improves the load requirements of composite manhole covers, which is in line with the international standard en124, which has been implemented since February 1, 2010. Since its establishment in 2004, Zibo bester has strictly implemented the production standards in accordance with the national standards. Customers can rest assured that we can be at ease.
