What is the minimum accepted galvanization for steel?

In this step, your product is completely immersed in a bath consisting of a min­imum of% pure molten zinc. The bath chemistry is specified by the American Society for Testing and Materials (ASTM) in Specification B6.

Your material is immersed in the bath long enough to reach bath temperature, or about°F (°C), then withdrawn slowly from the galvanizing bath whereby the excess zinc is removed by draining.

The chemical reactions that result in the formation and structure of the galvanized coating continue after the articles are withdrawn from the bath as long as the product is near the bath temperature. Your product is then cooled in a quench tank or ambi­ent air immediately after withdrawal from the bath.
