Quality Standards

The entire ranges of products are manufactured in the following standards:

  • - EN 124-2: 2015 : Gully tops and manhole tops for vehicular and pedestrian areas.
  • - ISO 1083 : 1987 : Spheroidal Graphite Cast Iron – Classification.

All major portion of these popular Ductile Iron manhole covers are Kitemarked by British Standards Institution (BSI).


Continuous assessment of quality system:

This has been achieved through an ISO-9001 2008 system, audited by BSI on annual basis. The Qualilty system covers castings made in Ductile Iron & Cast Iron.

We are in process of including Ni-hard, Mn- Steel, WCB and aluminum in our quality systems.


For some municipal castings, such as Ductile Iron Manhole covers & frames, we have obtained certification from BSI, known as Kitemark.

These certificates corresponds to manhole covers & frames, gullies and gratings manufactured to EN 124-2: 2015. Further, Kitemark is recognized around the world as a proof that a product has been manufactured, tested and fully complies with the technical requirements of the standard.

Ducast has been and will continue to be subjected to inspection and assessment by a specialist team of BSI observers, providing independent assurance, that an acceptable quality system and supporting quality control tests are in operation.
