In the current market, various Chongqing composite well cover manufacturers use different materials, but they still have the same characteristics:

1. Strong anti-theft property: the manhole covers produced by Chongqing composite manhole cover manufacturers are generally made of unsaturated resin, glass fiber and other materials through special production processes. After high-temperature grinding and pressing, the materials have no recycling value, and it is very difficult to take out the reinforcement.

2. Long service life: through the use of high-performance resin, glass fiber and special production process formula, the penetration of composite well cover in glass fiber is ensured, and the bonding force between the two is greatly enhanced, so that the material will not produce internal damage under the action of cyclic load, thus ensuring the service life of the product, as well as the same advantages of other resin Chongqing composite well cover. The disadvantage of poor adhesion is eliminated.

3. High/low temperature resistance, good insulation performance, strong corrosion resistance: the product is corrosion resistant, non-toxic and harmless. There is no metal additive, which has a real insulation effect. It can be used in complex, changeable, harsh and demanding places. The manhole cover produced by Chongqing composite manhole cover manufacturer has been tested by relevant national authoritative testing institutions, and has obvious acid and alkali resistance, corrosion resistance, aging resistance and other indicators that meet and exceed national standards.

4. Beautiful and practical, high grade: According to the needs of high-end customers, we can make personalized designs of complex LOGO and multiple colors on the same manhole cover surface, so that the design is exquisite, bright and clear. We can also make various imitation stone surfaces and colors that are the same as various stone pavements according to customer needs.

5. Strong bearing capacity: they generally adopt a special bottom type structure at the bottom, which increases the force bearing area by more than ten times or even dozens of times. The continuous reinforced fiber yarns used ensure the integration of fiber yarns and glass fiber cloth from the material, so that the product has sufficient bearing capacity. And meet or exceed national standards.

6. Environmental protection, anti-skid and low noise: the manhole cover will not slip after being rolled by the vehicle, and there will be no harsh noise and reverse phenomenon.
