Galvanized Sheet Metal: Must-Known Facts and Best Practices
The zinc coating works to prevent corrosive substances such as acid from reaching the base metal. Zinc saces its anode more readily than the base metal when the coating is scratched. Therefore, it offers complete protection from rusting. Zinc corrodes faster than the base metal. This activity is a great way of protecting the base metal.
