1680 Quality Sheet Specification
Galvanized,dual-phase steel with high yield strength for cold forming
AlternativesThere is no alternative to this sheet.
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.
