Quality and test certificates for every metal we supply

ISO 9001:2015 is the international standard for quality management systems. Our certificate, no. 1282043, was issued by Unitas Certification Services with a registration date of 12 March 2025 and an expiry date of 11 February 2028. In practical terms it means our enquiry review, purchasing, material identification, record keeping and complaint handling follow written procedures that an outside auditor checks.

ISO 9001 certifies the system, not a particular bar or pipe. Proof that a specific lot meets its grade comes from the test certificate.

Samples from the material are tested by a Government-recognised test house, and the results are issued on the test house's report. Where the mill's own certificate is available, that comes too. The two together let your QC team compare the numbers against the standard named on your purchase order, such as ASTM A312 for stainless pipe or ASTM A106 for carbon steel pipe.

If your project needs extra tests, such as intergranular corrosion, hydrotest records or IBR documents, put it in the enquiry so it can be priced and planned. Our guide on how to read a mill test certificate explains what each block on a certificate means.

• Test certificate showing chemical composition against the specified grade
• Mechanical results (tensile strength, yield, elongation, hardness) where the test applies to the product
• Identification that links the certificate to the material supplied
• Mill test certificate where the producing mill has issued one
• GST invoice listing grade, size and quantity
