It is a kind of composite material with glass fiber and its products as reinforcing material and synthetic resin as matrix material.
Compound manhole cover is a kind of manhole cover which is widely used now. In order to integrate it into different application requirements, the design of composite manhole cover has a variety of functions.
The composite manhole cover has the advantages that other manhole covers do not have. Suitable for all fields, long service life, reliable quality, no maintenance problems. At present, most of the composite manhole covers on the market have the characteristics of corrosion resistance, strong bearing capacity and large bearing capacity. The raw materials used in the whole production process are cheap and easy to obtain. The key is to have a good anti-destructive performance. Recovery and reuse has no use value, which greatly avoids the damage of the composite manhole cover.
The composite manhole cover has strong anti-corrosion ability. The mass loss shall not exceed 1%. In this way, there is no need to worry about the damage of the composite manhole cover caused by long-term wind and sun exposure. Its bearing working pressure level is also our confidence, the compressive strength level is tested by professional and technical personnel, can withstand more than 40 tons. According to the application requirements of customers, it can be used for anti-corrosion, anti-corrosion, anti-corrosion and other purposes.
