Advantages of Resin Rain Grates
Lightweight: The product weighs only about one-third of cast iron, making it easy for transportation, installation, and emergency repairs, significantly reducing labor intensity.
2. Anti-theft: Synthetic materials have no recyclable value, providing natural anti-theft protection; equipped with a locking structure to prevent theft of property within the well. This can prevent the occurrence of "urban black hole" incidents.
3. Strong weather resistance: Made from high molecular weight, chemically stable materials. Through scientific formulation, advanced technology, and complete technical equipment, this product can be used normally at temperatures ranging from -50℃ to +150℃.
4. High Precision: The product, made through high-temperature compression molding, features a tight combination gap between the lid and base, overcoming the issues of "running, jumping, and squeaking" in cast iron and concrete manhole covers. This enhances road traffic capacity and driving comfort.
5. Corrosion Resistance. Tested by the Chemical Building Materials Testing Center, the resin rain grate exhibits significant resistance to acids and alkalis and corrosion, with aging resistance indices reaching above level three, ensuring a long service life.
Now, the development trend of resin rain grates is toward more and more blocks. Resin composite manhole covers outperform cast iron ones in all aspects. The price of resin composite manhole covers is two-thirds lower than that of cast iron ones. Moreover, once formed, resin composite manhole covers have no recycling value, thus naturally deterring theft. As society progresses, the raw materials produced by humans are also increasing; it can be said that the latercomers of resin rain grates have the potential to adopt them.
