Gully tops and manhole tops for Vehicular and Pedestrian Areas - Part 3: Gully Tops and Manhole Tops Made of Steel or Aluminium Alloys
Also Known As:
The DIN EN 124-3 standard provides guidelines for gully tops and manhole tops made of steel or aluminium alloys. These tops are used to cover gullies, manholes, and inspection chambers in areas with pedestrian and/or vehicular traffic. The standard specifies the maximum clear opening size of 1000 mm for these tops. It also defines the various classes of areas where these tops can be used, ranging from areas only accessible by pedestrians and cyclists, to car parks and car parking decks, to road carriageways and hard shoulders.
The standard outlines the manufacturing process for these tops, which includes cold forming, mechanical crimping, or welding of metal components such as plates, strips, bars, or rolled/extruded sections. However, the standard does have some limitations. It is not applicable for manhole tops and gully tops made of aluminium tread plates for use in high wheel load areas or concave gratings for certain classes. It also excludes gratings/covers as part of prefabricated drainage channels, floor and roof gullies in buildings, and surface boxes.
