The high polymer FRP composite resin manhole cover produced by zibo best energy-saving materials co., ltd. has the advantages of light weight, high strength, excellent fatigue resistance, damage safety, simple forming, low rolling noise, good chemical corrosion resistance, good acid and alkaline resistance and beautiful appearance. Its comprehensive performance and economic index have surpassed that of cast iron well cover, and it can also solve the problem of stolen cast iron manhole cover.
At the same time, it can reduce the consumption of resources, which has important economic and social value.
1. Strong anti-theft performance: the manhole cover of resin composite material is made of unsaturated resin, glass fiber and other materials and reinforced framework by special production process. After one-time forming by high temperature grinding, the material has no recycling value. It is very difficult to take out the reinforcement (the cost of taking out the reinforcement exceeds the value of the reinforcement), so it has the function of active anti-theft.
2. Large bearing capacity
3. Long service life: through the use of high-performance resin, glass fiber and special production process formula, it ensures the penetration of resin in glass fiber, greatly enhances the adhesive force of the two, so that the material does not produce internal damage under the cyclic load, thus ensuring the service life of the product, and the same superiority of other resin composite manhole covers. The disadvantages of poor adhesion are eliminated.
4. Beautiful, practical and high-grade: according to the needs of high-end customers, we can make a personalized design of complex logo and multiple colors on the same manhole cover surface, so that the pattern is delicate, colorful and distinct. And can be made according to customer needs and all kinds of stone pavement the same imitation stone surface and color.
5. Weather resistance, good insulation and 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, bad and demanding places.
6. Environmental protection, anti-skid and low noise: the product will not slip, ear piercing noise and backlash after rolling. At the same time, due to the light weight of the product and the precise closure of the cover and seat, the problems of "jumping, seeping, ringing and shifting" of other manhole covers are overcome.
