Resin manhole cover has the advantages of light weight and high strength, excellent fatigue resistance, breakage safety, simple molding, low noise, good chemical resistance, good acid and alkali resistance, and beautiful appearance.
1. Strong anti-theft performance: Resin composite manhole cover is made of unsaturated resin, glass fiber and steel skeleton through special production process. After high temperature grinding and pressure forming, the material has no recycling value and it is difficult to remove the steel bar (rebar cost is greater than the steel bar value) .
2. Large carrying capacity: the bottom adopts a special pan bottom structure, which increases the load area by more than ten times or even dozens of times. The continuous reinforcing fiber is used to ensure that the fiber and glass fiber cloth are integrated into one material, so that the product has sufficient bearing capacity.
3. Long life
4. Beautiful and practical, high-grade: According to the needs of high-end customers, complex signs and personalized designs of multiple colors on the same manhole surface are made to make the design exquisite, colorful and clear.
5. High temperature / low temperature resistance, good insulation and strong corrosion resistance: the product is corrosion resistant, non-toxic and harmless. No metal additives, real insulation effect. It can be used in complex and changeable and harsh places.
6. Environmental protection, non-slip, low noise: The product has no slipping, no abnormal noise or ears after rolling. At the same time, due to the light weight of the product and the high precision of the cover and seat buckle, the problems of "jumping, rocking, ringing, and shifting" of other inspection manhole covers have been overcome.
