Steel grades for Hot rolled sections

Steel Grades

The AZ, AU, PU, PU-R, AS and HZ sections are delivered in the steel grades based on EN 10248-1 mentioned below. GU sections are available up to S 320 GP.

We can also provide steel grades complying with other standards. The table above compares the main standards used world-wide. For chemical composition, see the corresponding standard. 

Materials to other specifi cations 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 modifi ed grade A 690 with higher yield strength is also available upon request.

Galvanisation has an infl uence on the chemical composition of the steel and must therefore be specifi ed in the purchase orders.We strongly recommend informing us of all surface treatment to be applied to the product when placing orders.
