Manhole cover Ф600 D400 self-levelling with holes and locking system
Ductile iron manhole covers 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.
Manhole cover sizes and load classes are all dependent on their application. If you’re installing a new manhole cover or you’re replacing an existing one you’ll need to measure the space to ensure you get a perfect fit.
