FAQ
Frequently Asked Questions
Manhole covers according to DIN EN 124 are tops and covers for use in vehicular and pedestrian areas. They are classified according to different load classes. HUBER offers covers in the following sizes:
- A 15 for traffic areas that can only be used by pedestrians and cyclists (test load 15 kN).
- B 125 for footpaths, pedestrian zones and comparable areas, car parking areas and car parking decks (test load 125 kN).
- D 400 for carriageways of roads (including pedestrian streets), shoulders of roads and parking areas approved for any sort of road vehicles (test load 400 kN).
- E 600 for surfaces that are driven over with high wheel loads, e.g. dock facilities, aircraft operation areas (test load 600 kN).
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.
