Galvannealed Steel

ASTM A653
Coating Weights A40 and A60
CS, FS, DDS, EDDS, Types A, B & C

SS Grades 33 – 80

HSLA Grades 40 – 80


The hot-dip coating process produces a uniform zinc coating on both sides of the product. Immediately after the hot-dip process, the metal is immediately exposed to a heat treatment that allows the iron from the base metal to further diffuse into the zinc, creating a zinc-iron alloy layer.

Location Product Sheets:

Typical uses for Galvannealed Steel
Automobile applications, buses, trucks, trailers, garage doors, highway signs, vending machines

Formability
Galvannealed sheet can be formed in much the same manner and by the same variety of processes as galvanized sheet; however, the zinc-alloy coating on galvannealed sheet is more brittle than the zinc coating of galvanized sheet. As a result, some amount of powdering can appear when the metal is formed.

Paintable
Galvannealed steel is readily paintable.
