What is a rain grate?

The rainwater grate is part of the road drainage. The purpose of the design of the rainwater grate is to collect the impermeable rainwater on the road surface into the drainage system of the road, so as to prevent the road surface from being damaged by long-term rainwater immersion. A form of rainwater grate, generally one side of the rainwater grate has a curb stone called rainwater collection.

Application field

Rainwater grates are mainly used in municipal road drainage, water collection wells, residential areas, mining enterprises, and drainage pipes should be built in places with rainwater accumulation, so that excess water on the road surface can be discharged into the underground sewage pipe network. Well grates are essential for construction projects s material. Widely used in green belts, sidewalks, motor vehicle lanes, docks, alleys, communities, schools, etc.

Features

Compared with the previous cast iron water inlet, it has lower cost, lighter weight, strong impact load capacity, strong compression resistance, and also has the advantages of corrosion resistance, wear resistance, aging resistance, high impact resistance and long life.

In terms of structural design, the cover, frame, and grate are integrated, and the overall strength is high. The back of the cover is supported by a "#" support frame to prevent damage caused by heavy-duty vehicles. During the test, the vehicle with a traffic load of 20 tons has no damage; There is no damage to the inclined side of a vehicle over a ton at a speed of 30 km/h.
