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.

- If the maximumu value of uniform elongation is lower than 20 %, the value of n is determined between 10 % and Ag % (the maximum value of uniform elongation)
- The mechanical properties are valid for a period of 3 months from the date on which the products are made available.
- Tensile test values apply to "longitudinal" test pieces
