J Steel can also provide steel grades complying with other standards. The table above compares the main standards used worldwide. For comparison of chemical composition however, refer to the corresponding standard.
Materials manufactured to other specifications including S 460 AP, A 572 Gr. 65, as well as special steels with improved corrosion resistance (A 690), or copper addition in accordance with EN 10248 Part 1 Chapter 10.4, can be supplied on request. A modified grade A 690 with higher yield strength is also available upon request.
Galvanisation has an influence on the chemical composition of the steel and must therefore be specified. We strongly recommend that requirements for surface treatments are identified when placing orders.
