The polymer FRP composite manhole cover has the following characteristics:
1. Strong anti-human damage performance: composite manhole covers are generally made of unsaturated resin, glass fiber and other materials through special production process. After high temperature grinding and pressing, the products have no recycling value, and it is not so easy to extract reinforcement.
2. Service life: through the use of high-performance resin, glass fiber and special production process formula, the penetration of composite manhole cover in glass fiber is ensured, and the adhesive force of the two is greatly enhanced, so that the material will not suffer internal damage under cyclic load, so as to ensure the service life of the product, and the same advantages of other resin composite manhole covers, and effectively eliminate the adhesion strength The disadvantages of poor.
3. High temperature / low temperature resistance, good insulation performance, strong corrosion resistance: corrosion resistance, non-toxic and harmless. No metal additives. It can be used in complex, changeable, harsh and demanding places. The covers made by the manufacturers of the composite covers of wells have been tested by the relevant authoritative inspection organizations of the state. They have obvious acid and alkali resistance and corrosion resistance.
4. Beautiful and practical, high grade: according to the needs of high-end customers, we can make the personalized design of complex logo and various colors in the same manhole cover appearance, so that the pattern is delicate, colorful and clear. And can be made according to customer needs and all kinds of stone pavement with the same imitation stone appearance and color.
5. Strong bearing capacity: the bottom adopts a special design structure, and the continuous reinforced fiber is used to ensure that the fiber and glass fiber cloth are integrated in the material, so that the product has a certain bearing capacity.
6. Environmental protection, anti-skid, low noise: the manhole cover will not slip, ear noise and pollution after the car is rolled.
