Characteristics of SMC manhole cover

SMC manhole cover has multiple high-quality features

1. High strength: the use of polymer synthetic materials, with steel skeleton, molded by high-temperature molding, the highest test results of more than 40 tons, in line with and exceeding the latest CJ/T211-2005 standards issued by the Ministry of Construction of the People's Republic of China.

2. Beautiful appearance: the surface pattern of FRP manhole cover is beautifully designed and can be made into various patterns and colors to beautify the urban environment.

It can beautify the urban environment and is both beautiful and durable.

3. Light weight: the weight of the product is only about one-third of cast iron, which is convenient for transportation, installation and repair, and greatly reduces labor intensity.

4. Anti-theft: The synthetic material has no recycling value and is naturally anti-theft; it is also equipped with a locking structure to realize anti-theft of property in the well. Can completely eliminate the occurrence of "urban black hole" accident.

5. Strong weather resistance: the product selects high molecular weight material with high molecular weight and strong chemical stability as raw material, and can be used normally at - 40℃- 90℃ through scientific formula, first technology and perfect technical equipment.

6. High precision: because the product is molded by high temperature molding, cover and seat joint gap is small, overcoming the cast iron, cement manhole cover "running, jumping, ringing" and other problems, improve road accessibility and driving comfort.

7. Corrosion resistance: the product has been tested by the Chemical Building Materials Testing Center, has obvious acid and alkali resistance, corrosion resistance, anti-aging indicators to achieve more than three levels, long service life. The product has been used in a large number of municipal construction in various countries, well received by users and experts.
