Galvannealed Steel Sheet

When corrosion resistance, long service life and paintability are critical, Cincinnati Steel Products Co. recommends hot-dip galvannealed steel sheet.

This carbon steel sheet is coated on both sides by the continuous hot-dip process, then immediately subjected to an in-line heat treatment. This converts the entire coating into a zinc-iron alloy (the iron diffuses from the steel into the coating). The galvannealed surface has a non-spangled matte finish and may appear similar to uncoated cold-rolled steel.

The galvannealed surface is harder than a galvanized coating and the zinc-iron alloy can be welded more easily than galvanized. It is also more resistant to scratching and manufacturing damage and accepts painting readily, often without pre-treating.
