The tensile strength and compression performance of cast iron Manhole Covers are good. Compared with the resin composite and cement manhole cover, its extension rate is better. Ductile Iron Manhole Cover has good resistance to pressure, and it is durable, beautiful, reasonable price and not easy to damage. There's no substitute for the reliable products.
The characteristics of the ductile cast iron manhole covers:
1.High load: more than 40 tons, conform to the latest standards GB/T23858-2009.
2.Light weight: easy to transport, install, repair, and greatly reduce the labor intensity.
3.Anti-theft: manhole covers and seating integrated connection, It can not be damaged by a sledgehammer , completely security!
4.Corrosion resistance: It is a complex environment in well, filled with all kinds of chemicals. Ductile cast iron is not affected by chemical corrosion, the service life is more than 30 years.
5.High precision:The gap of cover and seating is small, overcome the manhole covers issues such as "run, jump, ring",improves the traffic capacity and driving comfort.
Application: Municipal roads and road drainage facilities, factory drain cover and basement drain, construction drainage facilities and inspection facilities.
