characteristic:
1. Strong anti-theft performance: resin composite material manhole cover is made of unsaturated resin, glass fiber and other materials. After high temperature grinding and pressing, the material has no recycling value, so it has active anti-theft function. Moreover, a locking device is added on the well cover. The manhole cover and the base are integrated into one, which requires special tools to open.
2. Large bearing capacity: 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 sufficient bearing capacity. The national standard product can bear more than 80 tons.
3. Long service life: through the use of high-performance resin, glass fiber and special production process formula, to ensure the penetration of resin in glass fiber Through, greatly enhanced the adhesion of the two, so that the material under the cyclic load, no internal damage, so as to ensure the service life of the product, and other resin composite well cover with the same advantages, put an end to the disadvantage of poor adhesion.
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 on the surface of the same well cover to make the pattern delicate and colorful. And can be made according to customer needs and all kinds of stone pavement with the same imitation stone surface and color.
5. High temperature / low temperature resistance, good insulation performance, strong corrosion resistance, corrosion resistance, no metal additives, can be used in complex and changeable, harsh and demanding places. The manhole cover have been tested by relevant authoritative testing institutions, and have obvious acid and alkali resistance, corrosion resistance and anti-aging ability.
6. Environmental protection, anti slip and low noise: the product does not skid, harsh noise and reverse phenomenon after rolling. At the same time, due to the light weight of the product and the precise closure of the cover and seat, it overcomes the problems of other inspection well covers such as "jumping, seeping, ringing and shifting".
