What is the process called that coats steel with zinc to prevent corrosion?

Explanation:
Coating steel with zinc to prevent corrosion is galvanization. Zinc protects iron-based metals both as a barrier and as a sacrificial anode: when moisture and oxygen reach the coating, zinc corrodes first, preserving the steel underneath. The common method is hot-dip galvanizing, where steel is dipped into molten zinc to form a strong, adherent coating. Other options like anodizing, plating, or chrome coating don’t specifically describe zinc protection for steel, so galvanization is the precise term for this corrosion-preventing process.
