Composite manhole cover use high temperature molding press technology. The manhole cover have weather resistant and work temperature: -50℃-150℃.
Features:
Environmental protection, non-slip, low noise: This product does not slip, no harsh noise and anti-interference phenomenon after the car is rolled. At the same time, due to the light weight of the product and the tight closure of the cover and seat, it overcomes the problems of "jumping, rocking, ringing, and shifting" of other composite manhole covers.
Long service life: through the use of high-performance resin, glass fiber and special production process formula, to ensure the running-in of the resin in glass fiber, greatly enhance the adhesion between the two, so that the material under the action of cyclic loading, not Internal damage occurs, which guarantees the service life of the product and the same superiority of other resin composite manhole covers. Eliminate the disadvantages of poor adhesion.
This resin composite manhole cover is made of glass fiber and resin as the basic materials and a curing agent as the auxiliary material. Its weight is two-thirds lighter than cast iron manhole covers, and its service life is more than 20 years, which is twice that of cast iron manhole covers, and the price is only 80% of that of cast iron manhole covers. At the same time, this manhole cover also has the characteristics of insulation, no noise, corrosion resistance, high and low temperature resistance.
