Our pressed steel manhole covers are manufactured in the UK by Clark-Drain under the quality management system ISO 9001:2015.
All of our steel covers are galvanised to ensure that they are long-lasting and resistant to corrosion.
What does galvanised mean?
The galvanising process is carried out to BS 1461. Galvanising essentially involves applying a coating of zinc to the steel by dipping it into a zinc bath. At this time the iron within the steel reacts with the molten zinc to form a uniform coating that protects the steel by creating a barrier that keeps any corrosive particles in the atmosphere away from the base steel substrate.
The frames for our steel covers are made from strong polypropylene.
