Composite Manhole Cover Called Anti-theft Manhole cover?

Composite Manhole Cover Called Anti-theft Manhole cover?

Composite Manhole Cover also called Resin Manhole Cover, polymer manhole cover, anti-theft manhole cover and so on.

Composite resin manhole cover is made of unsaturated resin as matrix material and long glass fiber as reinforcing material. Because the structure of pot bottom is adopted, the stress of data is average, and the application of continuous fiber reinforcement does not require reinforcing steel bar. The material is all composite material, which is formed by high temperature moulding once more.

Anti-theft manhole cover


1.The anti-theft performance is strong: the resin composite manhole cover is made of unsaturated resin, glass fiber and steel skeleton by special production technology. It is formed by high temperature grinding and pressing once, and the material has no use value. It is very difficult to take out the steel bar (the cost of taking out the steel bar exceeds the value of the steel bar). Therefore, it has the function of active anti-theft.

2.Bearing capacity is large: special bottom structure is adopted at the bottom of the pot, which enlarges the stress area by more than ten times or even dozens of times. The continuous reinforcing fibre yarn used ensures that the fibre yarn and the fiberglass cloth are integrated from the material, so that the product has sufficient carrying capacity.

3. Long service life: Through the use of high performance resin, glass fiber and special production process formula, guaranteed the resin in glass fiber running-in, greatly enhanced the adhesion between the two, so that the material under cyclic load, without internal damage, thus ensuring the service life of the product, and other resin composite well cover. Equal superiority. The disadvantage of poor adhesion was eliminated.

4. Beautiful and practical, high-grade: according to customer needs, can make complex LOGO and a variety of colors in the same well cover surface personalized design, so that the pattern is delicate, bright and distinct. And can be made according to customer needs and all kinds of stone pavement with the same imitation stone surface and color.

5. High/low temperature resistance, good insulation and corrosion resistance: product corrosion resistance, no metal additives, played a sense of insulation effect. It can be used in complex, changeable, harsh and demanding places. The product has obvious acid and alkali resistance and corrosion resistance after testing by relevant testing institutions.

6. Environmental protection, anti-skid, low noise: the product does not skid, no harsh noise and reverse phenomenon after rolling. At the same time, due to the light weight of the product and the tight fastening of the cover and seat, the problems of jumping, stirring, noise and displacement of other inspection covers are overcome.


The features of the resin composite manhole cover is that it is made of polymer composite material and has no recycling value. After the popularization of resin manhole covers, the problem of black holes in cities caused by stealing manhole covers will be solved. Therefore, composite manhole covers are also called burglar-proof manhole covers.

The resin composite well cover is made of glass fiber and resin as basic materials and curing agent as auxiliary materials. Its weight is two-thirds lighter than that of cast iron manhole covers. Its service life is more than 20 years, twice that of cast iron manhole covers, and its price is only 80% of that of cast iron manhole covers. At the same time, this kind of well cover also has the characteristics of insulation, no noise, corrosion resistance, high and low temperature resistance.

Zibo Best Energy Saving Material Co., Ltd., founded in 2004, product design, mold development, color allocation, product testing, etc. Main products: compound manhole cover, polymer manhole cover, resin manhole cover, rainwater grate, cable ditch cover, Trench Cover, U-shaped drainage ditch, trench cover, etc. With its unique formula and technology, it has created the anti-theft and artistic characteristics of composite well cap, and is the representative of the national standard high quality composite well cap in the current well cap industry.

Resin composite manhole cover is gradually integrated into our life with its unique advantages. Streets and alleys, urban main roads, garden districts, underground garages, factory workshops and so on, it is everywhere.
