What type of steel is coated with zinc?

• A. Stainless
• B. Galvanized
• C. Carbon
• D. Alloy

Answer: (B)

Zinc coating is used to protect steel from corrosion, giving you a material known as galvanized steel. The zinc acts as a sacrificial layer, corroding before the steel and extending the life of outdoor or moisture-exposed members. Galvanizing is typically done by hot-dip or electrogalvanizing, applying the zinc directly to the steel surface. Stainless steel isn’t described by a zinc coating because it already resists corrosion due to its chromium content, so galvanizing isn’t the standard practice. Carbon steel and alloy steel refer to the base metal compositions, and while they can be galvanized, the term that specifically describes a zinc-coated steel is galvanized steel.
