Ductile Iron Chamber Cover, Cast Iron Drainage Covers and Grates Guide

As of the date of writing this article, the Bureau of Indian Standards does not have a separate code for Ductile Iron manhole covers. As a result, the most popular code used in India is the European EN124.

Manhole covers and grates up to and including a clear opening of 1000 mm are divided into 6 load classes.

  • A 15 : Capable of withstanding 15kN or 1.5MT of load. They are suitable for areas which can only be used by pedestrians and pedal cyclists.
  • B 125 : Capable of withstanding 125kN or 12.5MT of load. They are ideal for pedestrian areas and comparable areas, car parks or car parking decks.
  • C 250 : Capable of withstanding 250kN or 25 MT of load. The area of kerbside channels of roads which, when measured from the kerb edge, extends a maximum of 0.5 m into the carriageway and a maximum of 0.2 m into the pedestrian area.
  • D 400 : Capable of withstanding 400kN or 40 MT of load. The carriageways of roads (including pedestrian streets), hard shoulders and parking areas, for all types of road vehicles.
  • E 600 : Capable of withstanding 600kN or 60 MT of load. Areas imposing high wheel loads, e.g. docks, aircraft pavements.
  • F 900: Capable of withstanding 900kN or 90 MT of load. Suitable for areas imposing particularly high wheel loads, e.g. aircraft pavements.

Are you concerned about our Covers & Frames being lighter and not being able to withstand the load?

  • We have been exporting DI Covers & Frames for over a decade now. Our designs conform to international standards and these are the conventional weights of manhole covers used in countries like Italy, Spain, the UK and more. We are utilizing the same design technology for the Indian market as well that will help contractors save money.
  • Our foundry strictly follows the Ductile Iron grade 500-7 metallurgical standard, which ensures our products can withstand the heavy loads with light weights.
  • Our designs have been vetted by reputed 3rd party inspection agencies, thus reinforcing our manufacturing and design technology.
