A water strainer is a cover plate that serves as a filter at the entrance of a sewer on the street. Whether it is square or round, it is usually flat on top. In this way, it will not hinder the passage of traffic vehicles, beautify the road, and prevent theft.
Characteristics of water grates:
1. Lightweight: The weight is only about one-third of cast iron. Easy to transport, install, and repair, and also greatly reduces labor intensity.
2. Anti theft: This synthetic material has no recycling value and naturally prevents theft. And it is equipped with a locking structure to prevent theft of property inside the well, which can completely prevent the occurrence of "urban black hole" accidents.
3. Good weather resistance: The raw material is a polymer material with high molecular weight and chemical stability. The product can be used normally at -50 ℃ -+150 ℃ through scientific formulas, high-level processes, and perfect technical equipment.
4. High precision: After high-temperature molding, the gap between the cover and seat is small. Overcoming the problems of "running, jumping, and making noise" around cast iron and cement manhole covers, the road capacity and driving comfort have been increased.
5. Corrosion resistance: The product has been tested by the National Chemical Building Materials Testing Center. It has obvious acid and alkali resistance, corrosion resistance, anti-aging index of more than three levels, and long service life.
