This method is also employed on ship hulls as well as other steel objects in contact with highly corrosive environments. Galvanized conduit and tubing is galvanized to deter rust from small scratches. The galvanized coating will sacrifice itself. Zinc Ingot is refined metallic Zinc in an ingot form.
