Another biggest feature of the composite manhole cover is that it has no recovery value at all, completely solves the problem of anti-theft, and effectively reduces the phenomenon of theft of the manhole cover. Let us take a look at the specific advantages of the composite manhole cover.

High strength: high-molecular-weight composite plastic composite material with high compressive, bending, and impact strength, and toughness. After being used for a long time, the product will not be crushed and damaged, which can completely prevent the occurrence of urban black hole accidents.

Beautiful appearance: Exquisite designs on the surface of inspection manhole cover are designed to beautify the urban environment.
Easy to use and light weight: the product weighs only about one third of cast iron, which is convenient for transportation, installation and repair, which greatly reduces labor intensity.
Anti-theft: The composite plastic composite material has no recycling value and is natural anti-theft; according to customer needs, a locking structure is provided to prevent theft of property in the well.
Strong weather resistance: This product uses high molecular weight materials with large molecular weight and strong chemical stability as raw materials for manhole covers. Through scientific formula, advanced technology and perfect technical equipment, the product can be used normally at 120 ℃.

Low noise: The application of synthetic materials and the special locking structure design completely solve the problem of noise caused by inspection manhole covers to the city.

The composite manhole cover uses unsaturated resin as the base material and continuous glass fiber as the reinforcing material for the composite material manhole cover. Because the bottom structure is used in the structure, the material is uniformly stressed, and it is reinforced with continuous fibers, without reinforcement. The materials are all composite materials. The bearing capacity and later bearing capacity of the manhole cover are guaranteed. From the perspective of bearing capacity, the service life is longer; the manhole cover is layered and compounded, and the open-air part is made of wear-resistant and anti-aging materials. From the point of view of rolling resistance and aging resistance of vehicles , The service life is relatively long.
