Features of manhole cover:
1. Strong anti-theft performance: The resin composite manhole cover is made of unsaturated resin, glass fiber and other materials and steel frame by special production process. After high temperature grinding and molding, the material has no recycling value. It is very difficult to take out the steel bar. The cost exceeds the value of the steel bar) and therefore has the function of active anti-theft.
2. Large bearing capacity: The bottom of the bottom adopts a special pot bottom structure, which increases the force area by a dozen times or even dozens of times. The continuous reinforcing fiber yarn used ensures the fiber filament and the glass fiber cloth together in a material, so that the product has sufficient carrying capacity.
3. Long service life: By using high-performance resin, glass fiber and special production process formula, the penetration of resin in glass fiber is ensured, and the adhesion between the two is greatly enhanced, so that the material does not under the cyclic load. Internal damage is created to ensure the longevity of the product and the superiority of other resin composite well covers. Eliminate the disadvantages of poor adhesion.
4. Beautiful and practical, high grade: According to the needs of high-end customers, we can make complex LOGO and multi-color personalized design on the same manhole cover surface, making the pattern delicate, colorful and distinct. According to the customer's requirements, we can make all kinds of imitation stone surfaces and colors that are the same as various stone pavements.
5. High temperature resistance/low temperature, good insulation performance and strong corrosion resistance: the product is resistant to corrosion and metal-free additives, which has a true insulation effect. It can be used in places that are complex, varied, and demanding. The product has been tested by relevant authoritative testing institutions and has obvious acid and alkali resistance, corrosion resistance and anti-aging ability.
6. Environmental protection, non-slip, low noise: This product does not slip, no harsh noise and reverse phenomenon after the car is crushed. At the same time, due to the light weight of the product, the cover and the seat are fastened, which overcomes the problems of “jumping, smashing, ringing, shifting” of other inspection manhole covers.
