Is ductile iron manhole cover really as good as the legend

When choosing a manhole cover, many people will discuss which manhole cover will be better. Compared with gray iron manhole covers, the favorable rate of ductile iron manhole covers is significantly more. Some people say that after the development of cast iron manhole covers to ductile iron this process, it is already very good, so there is a certain basis, but it can not be said to be perfect. How about ductile iron manhole cover? See from which aspects to look.

How about a gas station manhole cover made of DSD material
