Product DescriptionGalvannealed sheet is carbon steel sheet coated with zinc on both sides using a continuous hot dip process. The zinc coating is harder than a regular galvanized coating and is more resistant to scratching and manufacturing damage. However, the harder coating is susceptible to powdering if the sheet is severely formed during fabrication.
Galvannealed sheet is specifically designed to be used in the painted condition. When painted with properly selected primers and paints, the combined paint/galvannealed coating offers excellent resistance to peeling and/or blistering of the paint, compared with conventional galvanized sheet.
A60 refers to galvanneal coating of .60 oz. per square foot. The A60 coating has 50% more protective coating and 50% more protection than the A40 coating.
