Features：

Strong anti-theft performance: Resin composite manhole cover is made of unsaturated resin, glass fiber and other materials and steel skeleton through special production process. The cost exceeds the value of the steel bar) so it has the function of active anti-theft.

Large bearing capacity: the bottom adopts a special pot bottom structure, which increases the stress area by ten times or even dozens of times. The continuous reinforcing fiber yarn used ensures that the fiber yarn and glass fiber cloth are integrated from the material, so that the product has sufficient bearing capacity. And meet or exceed the national standard.

Long service life: through the use of high-performance resin, glass fiber and special production process formula, the penetration of the resin in the glass fiber is ensured, and the bonding force between the two is greatly enhanced, so that the material will not be damaged under cyclic loads. Internal damage occurs, thereby ensuring the service life of the product, and the same superiority as other resin composite manhole covers. Put an end to the disadvantages of poor adhesion.

Beautiful and practical, high-grade: According to the needs of high-end customers, we can make personalized designs of complex LOGO and multiple colors on the surface of the same manhole cover, so that the patterns are delicate, the colors are bright and distinct. And can be made into a variety of imitation stone surfaces and colors that are the same as various stone pavements according to customer needs.

High temperature/low temperature resistance, good insulation performance, strong corrosion resistance: the product is corrosion resistant, non-toxic and harmless. Without metal additives, it has a real insulation effect. It can be used in complex, changeable, harsh and demanding places. The products have been tested by relevant national authoritative testing institutions, and have obvious acid and alkali resistance, corrosion resistance, anti-aging and other indicators that have reached and exceeded national standards.

Environmental protection, anti-slip, low noise: the product does not slip, has no harsh noise and backlash after being rolled by a car. At the same time, due to the light weight of the product and the precise fastening of the cover and seat, it overcomes the problems of "jumping, swaying, ringing, and shifting" of other inspection manhole covers.

Product Features：

The biggest feature of resin composite manhole covers is that they are made of polymer composite materials and have no recycling value. After the popularization of resin manhole covers, the problem of stealing manhole covers and causing urban black holes will be easily solved. Different from the manhole covers on the market, it is pressed out by a hydraulic press and has a high impact resistance. "

This resin composite manhole cover is made of glass fiber and resin as basic materials, and made of curing agent, accelerator, etc. as auxiliary materials. Its weight is two-thirds lighter than cast iron manhole covers, and its service life is more than 20 years, twice that of cast iron manhole covers, while the price is only 80% of cast iron manhole covers. At the same time, this kind of manhole cover also has the characteristics of insulation and no noise. Chifeng City Product Quality Supervision and Inspection Institute conducted a load and impact strength test on this manhole cover, and found that the load capacity of this manhole cover is 24 tons, and its impact strength exceeds that of ordinary manhole covers.
