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.

  1. Guarantee periods of absence of stretcher strains marks and mechanical properties are 6 months. The period begin on the date on which products are made available.
  2. Tensile test values apply to "transverse" test pieces
  3. Absence of stretcher strains marks is valid if storage temperature is below 50° C.
