Cast iron sewage grate 400X400/C250
Ductile iron sewage gratings are very strong and resilient. Ductile iron, also known as cast iron, is used because it has great strength. This material then lends itself to a long-life span for installation in roads, highways, airports, car parks and other heavy duty industrial areas.
Sewage grating is an important part of the urban drainage system everywhere, so reliable quality is needed to ensure the safety of public facilities, rather than breaking at any time under the trampling or rolling of many people. At the same time, high-quality Sewage Grating can reduce replacement costs and control the overhead of urban public facilities.
