Galvannealed sheet is carbon steel coated with zinc on both sides by the continuous hot dip process.
After undergoing the coating bath, the zinc coating is subjected to an in-line heat treatment that converts the entire coating to a zinc iron alloy. Conversion to the alloy results in a non-spangled matte finish which makes the sheet suitable for painting. The coating is harder than a regular galvanized coating and is more resistant to scratching and manufacturing damage.
Painted applications such as automotive appliances, boating equipment, agricultural equipment and household appliances.
