As quality is the backbone of our business we undergo extensive testing on all materials at various stages in production. Tests can be done both in-house or at external, independent test houses.

In-house testing


One of the most important tests we do in-house is PMI testing.

PMI stands for Positive Material Identification. Our 3 state of the art PMI machines use X-Ray technology to determine the grade of material, in a few seconds. We perform PMI tests on all received raw material on receipt and issuing to jobs, plus random inspection through manufacture and at final inspection.

We can supply test results if needed.

Hardness Testing

We perform hardness tests in-house when required by the customer or specification.

Proof load testing

SSF has proof-load testing facilities; these tests are carried out in-house as and when required.

Independent testing

SSF uses UKAS-accredited independent test houses for most testing requirements. This gives our customers the confidence of an unbiased test from a 3rd party. Some examples of tests available are:

  • Corrosion testing
  • Impact testing
  • Tensile strength tests
  • Finished product tests
  • Chemical analysis tests
  • CHARPY tests
  • Others to customer specification
