DIN Standards


DIN steel stockholders and suppliers, delivering to the whole of the UK. DIN steel specifications are German standards developed by the “Deutsches Institut für Normung”, meaning “German Institute for Standardisation”. The institute is a member of the European Committee for Standardization (CEN) and the International Standards Organization (ISO).

As a non-profit organisation “Deutsches Institut für Normung” develops DIN steel standards, which are reviewed every five years. DIN specifications are preceded by the letters DIN and followed by a combination of letters and numbers showing chemical symbols and numbers. This descriptive code can give guidance as to the composition of the steel. Also contained under the umbrella of these steel standards are the Werkstoff Numbers (Material Numbers) which use numbers only with a decimal point after the first digit.

We welcome export enquiries for DIN steel standards. Contact our sales office and consult our shipping policy for details.
