What is ductile iron?
Leaving the science aside, the main difference between ductile iron and other types of cast iron is that it is much less brittle. This means that it is more flexible than traditional gray cast iron and generally has a higher tensile strength.
Ductile Iron is the most popular type of iron alloy in areas where impact resistance is important, such as manhole covers. Other common applications include pipes, automotive parts and bollards.
Our ductile iron manhole covers are manufactured by Clark-Drain to BS EN 124-2:2015, which is the standard that specifies where each class of cover can be installed. Our range of ductile cast iron manhole covers can be used for all types of loadings from pedestrian to airports.
