Flat / Galvanised
Galvanized flat steel is manufactured by zinc-coating both sides of cold rolled metal by hot-dipping process. After having coated the steel surface with zinc, the coating of the interface is transformed into an alloy of iron-zinc layer through heating by induction and the galvannealed steel is produced.

- The values of tensile strength for all the steel grades may be expected to be within a value range of 140 N/mm² (14,3 kg/mm²)
- The mechanical properties are valid for a period of 1 months from the date on which the products are made available.
- Tensile test values apply to "longitudinal" test pieces
