Manhole step NO1 is a galvanised steel nonslip step for brick and reinforced concrete manholes. The overall length of the step is 250mm and the internal step measures 125mm width. Steps are fitted within the manhole so that maintenance engineers can access underground chambers, to perform scheduled checks, repairs, or upgrades.
Manhole step NO1 is manufactured in galvanised steel, to ensure that corrosive substances are unable to reach the underlying steel. This ensures that the steel fitting keeps its structural integrity when fitted to brick or concrete walls within the manhole.
