Resin covers

Short Description:

product presentation :

1. Strong anti-theft performance: resin composite material manhole cover using unsaturated resin, glass fiber and other material and reinforced skeleton compounded by the special production process, after high temperature and press for a forming, material recycling value, it is very difficult to remove the steel bar (take out the value of steel costs more than steel) so it is of active anti-theft function.
2. Large bearing capacity: the bottom of the special pot bottom structure, so that the stressed area increased ten times or even dozens of times.The continuous reinforcement fiber is used to ensure the fiber fiber and glass fiber cloth are integrated in the material, so that the product has sufficient carrying capacity.And meet or exceed national standards.
3. Long service life, through the adoption of high performance resin, glass fiber and special formula, production process to ensure that the penetration of resins in glass fiber, greatly enhanced the stick relay, make the material under cyclic loading, do not produce internal damage, so as to ensure the service life of the product, and other resin composite manhole cover with the same advantages.Put an end to the drawbacks of poor adhesion.
4. Beautiful and practical, high grade: According to the needs of high-end customers, we can make a complex LOGO and a variety of colors on the same manhole cover surface of personalized design, so that the pattern is delicate, bright colors, distinct.And can be made according to customer demand and all kinds of stone pavement the same imitation stone surface and color.
5. High/low temperature resistance, good insulation and strong corrosion resistance: corrosion resistance, non-toxic and harmless.No metal additives, played a real sense of insulation effect.It can be used in complex, changeable, harsh and demanding places.The products have been tested by the relevant national authoritative testing institutions, with obvious acid and alkali resistance, corrosion resistance, anti-aging and other indicators have reached and exceeded the national standards.
6. Environmental protection, anti-skid, low noise: the product will not slip, no harsh noise and reverse phenomenon after the vehicle is run over.At the same time, due to the light weight of the product, cover, seat buckle precision, overcome other inspection cover "jump, stilt, sound, displacement" and other problems.

product feature :

The resin composite manhole cover is made of polymer composite material and has no recovery value.After the resin manhole cover is popularized, the problem of urban black hole caused by stealing manhole cover will be solved.Different from the manhole cover on the market, it is pressed out with a hydraulic press, the impact strength is greater.
The resin composite manhole cover is made of glass fiber and resin as the basic material, curing agent, accelerator and other auxiliary materials.It weighs two thirds less than cast iron manhole covers and has a service life of more than 20 years, twice as much as 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 insulation, noiseless characteristic.Chifeng product quality Supervision and Inspection Institute carried out load and impact strength test on this manhole cover, and found that the load force of this manhole cover is 24 tons, and the impact strength is also higher than the ordinary manhole cover.
