In recent years, the utilization rate of composite manhole covers has become higher and higher, and everyone has gradually accepted this new type of light manhole cover.
Product advantages of composite manhole cover:
1. Strong anti-theft performance: Resin composite manhole cover is made of unsaturated resin, glass fiber and other materials and reinforced steel skeleton through special production process. After high temperature grinding and pressing, the material has no use value and it is very difficult to take out the steel bar (rebar cost) (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 area under load by a dozen times 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 resin in glass fiber, greatly enhance the adhesion between the two, so that the material under the action of cyclic loading, 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 manhole, personalized design, making the pattern delicate, colorful 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 and 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
