Rainwater ductile cast iron manhole cover

Rainwater ductile cast iron manhole cover is mainly used for rain pipe Wells, the following is its detailed introduction: 1. Material: ductile cast iron material, strong pressure resistance, corrosion resistance, long service life and so on. 2. Load: The load of thisrainwater ductile cast iron manhole coverr is 400 kN, which can probably carry a load of about 40 tons. 3. Design: The logo of "rain" is printed in the middle of the manhole cover, indicating that it is a rainwater pipe, easy to identify and convenient for future maintenance. Moreover, the raised "cross" pattern design on the manhole cover increases the friction force and helps to prevent slip. In addition, our company has a research and development team, can customize various sizes and patterns of manhole covers.
