Frequently Asked Questions
Stainless steel manhole covers are corrosion-resistant, maintenance-free and very durable. This gives planners and operators the security of using a manhole cover that will still function perfectly decades from now.
The term "surface-watertight” means that the manhole cover is protected against the ingress of natural precipitation such as rain or other surface water that occurs without pressure.
We speak of a flood-proof cover when it is flooded, for example, by high water. The manhole cover remains resistant to water penetration up to a certain water column. A backwater-proof manhole cover prevents water from penetrating from the inside of the manhole to the outside.
Manhole covers should be manufactured according to "DIN 1239 - Coverings for wells, spring water chambers and other water supply construction - Principles of construction”.
