Metallographic Lab Services

SHARE
To ensure that the coatings and cladding we provide meet the highest standards, we have a comprehensive testing lab on the premises that is permanently staffed. ASTM compliant and custom reports are produced to client requirements. Third-party verification is also available from a non-destructive testing company co-located on our compound in an outbuilding.
