The composite manhole cover is made of glass fiber, unsaturated resin, and a certain amount of filler after high temperature molding. Also called resin manhole cover, glass fiber manhole cover, polymer manhole cover, fiberglass manhole cover, moulded manhole cover and so on.


Some product advantages of composite manhole covers:
1. Strong anti-theft performance: Resin composite material manhole cover is made of unsaturated resin, glass fiber and other materials and reinforced skeleton composited by special production process. After high temperature grinding and pressing, the material has no use value, and it is very difficult to remove the steel bar (Beyond the value of steel), so it has the function of active anti-theft.
2. Large bearing capacity: the bottom adopts a special pan-bottom structure, which increases the load area by dozens or even dozens of times. The continuous reinforcing fiber yarn used guarantees that the fiber yarn and the glass fiber cloth are integrated into one material, so that the product has sufficient bearing capacity.
3. Long service life: through the use of high-performance resin, glass fiber and special production process formula, to ensure the running-in of the resin in glass fiber, greatly enhance the adhesion between the two, so that the material under the action of cyclic loading, not Internal damage occurs, which guarantees the service life of the product and the same superiority of other resin composite manhole covers. Eliminate the disadvantages of poor adhesion.
4. Beautiful and practical, high-grade: According to customer needs, complex LOGO and a variety of colors can be made on the surface of the same well cover personalized design, making the pattern delicate, bright and clear. According to customer requirements, we can make all kinds of imitation stone surfaces and colors the same as various stone pavements.
5. High temperature / low temperature resistance, good insulation performance and strong corrosion resistance: the product is corrosion-resistant and has no metal additives, which has a significant insulation effect. Can be used in complex, changeable, harsh, and demanding places. The product has been tested by relevant testing agencies and has obvious resistance to acid and alkali and corrosion.
6.Environmental protection, non-slip, low noise: This product does not slip, no harsh noise and anti-interference phenomenon after the car is rolled. At the same time, due to the light weight of the product and the tight closure of the cover and seat, it overcomes other problems such as "jumping, rocking, ringing, and shifting" of other inspection manhole covers.
A prominent feature of the compound manhole cover is anti-theft. Why do you say that. Because of the particularity of the material of the composite manhole cover, the material itself has no secondary use value and plays a natural role in preventing theft. Therefore, the manhole cover with or without the lock will not cause the thief's attention. The compound manhole cover with a lock is to better protect the normal use of the equipment in the well. The use of composite manhole covers directly solves the problem of stolen manhole covers.
