The resin manhole covers made by Zibo energy energy saving materials Co., Ltd. are widely used in municipal roads, communications and power, transportation facilities, petrochemical industry and other industries. The company produces resin manhole covers with the characteristics of light weight, anti-aging, frost resistance, high temperature resistance, strong corrosion resistance, strong bearing capacity, smooth surface, uniform color inside and outside, non fading, high load-bearing and good toughness. Performance resin, glass fiber and special production process formula ensure the penetration of composite manhole cover in glass fiber, enhance the adhesion of the two, so as to ensure the service life of the product without internal damage under the action of cyclic load. The resin manhole cover is molded at high temperature, and the gap between the cover seat is small, which overcomes the disadvantages of cast iron and cement manhole covers such as "running, jumping and ringing" It improves the road capacity and driving comfort.
SMC resin manhole cover is light in weight, low in price and beautiful in appearance. It can be coloured, easy to install and maintain. It has solved the problem of burglar prevention because of no recycling value. Adding ultraviolet absorber and other anti-aging agents will make the wear-resistant and service life of the products increase exponentially. It is not reinforced by steel frame, but reinforced by glass fiber composite. It has the strength of compression resistance, bending resistance and impact resistance, and has toughness. It can reach six load levels of national standard a, B, C, D, e and F. the installation of intelligent equipment will not shield the signal of intelligent equipment, so it is the preferred equipment carrier for intelligent manhole cover. And acid and alkali resistance, corrosion resistance, wear resistance, rolling, no noise. The unique design of Zibo bester manhole cover can solve the problems of traditional manhole cover such as running, jumping, ringing and overturning. Professional production manhole cover, high quality manhole, cover safety and practical, timely delivery.
