Galvannealed Steel Sheet
Galvannealed 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.
Products manufactured using galvannealed steel sheet include:
- Vehicle components that require corrosion-resistance
- Exterior partitions, covers, cabinets
- Vending machines.
O’Neal Steel carries ASTM A653 sheet.
