Accreditations & Quality

Over the years Sheffield Forgemasters has developed numerous Quality Management Systems and acquired accreditations to international standards. This demonstrates our commitment to providing the highest quality products and services to our customers whilst continuously developing.  

In addition to the accreditations held, Sheffield Forgemasters has extensive experience in working to international nuclear codes such as ASME B&PV code and RCC-M.

Our Quality accreditations are supported by our test house which is a UKAS accredited facility. (UKAS 4355) for mechanical testing including fracture toughness.


Our internal QA in each area of our organisation monitors the day to day activities while a central quality function carries out a comprehensive internal audit programme. This maintains the Quality Management Systems ensuring subcontractors can achieve the high standards expected whilst providing support. The Quality Director alongside an experienced team ensures the highest practices and procedures are in place throughout the organisation.

Quality is the responsibility of every employee at Sheffield Forgemasters. Quality awareness training sessions are an important part of development for each member of the workforce.

In addition to the quality indoctrinations we have detailed code and standard specific training sessions, which are held frequently to indicate the importance of our high integrity standards.
