List of rolling marks on reinforcing steels

Warning
The following is only informative. It enables the reader to guide its searching. Any information got here should be verified by questioning the concerned producer.
Some factories may not exist any more. Corresponding rolling marks are kept in the list to facilitate identification of old steels.
Two main types of identification procedures exist: European way, which consists in a sequence of numbers and North american. Other identifications also exist but are not driven by a fixed procedure.
If you are aware of any other mark, existing of having existed, any other website providing a list including rolling marks please advise us.
European procedure
The European procedure is made of a sequence of figures:
- a beginning of sequence: number "0" (against EN 10080 standard), or dot-dash-dot when the steel is CARES certified,
- a number providing the country of manufacturing of the steel (see here after),
- a number made of one or two figures, to identify the factory.
List of codes per country:
| Code | Countries |
| 1 | Austria, Czech republik, Germany, Poland, Slovakia |
| 2 | Belgium, Luxemburg, Netherlands, Switzerland |
| 3 | France, Hungary |
| 4 | Italy, Malta, Slovenia |
| 5 | Ireland, United Kingdom |
| 6 | Denmark, Finland, Estonia, Iceland, Latvia, Lithuania, Norway, Sweden |
| 7 | Portugal, Spain |
| 8 | Cyprus, Greece |
| 9 | Other countries |
Figures are determined in one of the following manners:
- count the number of normal ribs between enlarged or missing ribs or dots,
- figure rolled onto the steel.
See an example of counting normal ribs between enlarged ribs:
For indented steels, the same procedure applies, replacing ribs by protrusions between indentations.
See here after an informative list of existing rolling marks (identification of the country is made with the ISO 3166-1 codes).
