Galvanized steel is often used as is, but is also frequently coated. The issue with galvanized steel is that the galvanized substrate is changing with time as the zinc surface oxidized rapidly to zinc oxide, and more slowly to zinc carbonate. Hence, the substrate is changing with time, and this can result in variable overcoating performance.Galvanized Steel Chemical Resistance Chart - Reviews Of ChartJan 22, 2020 · Galvanized Steel An Overview Sciencedirect Topics.

Galvanizing protects the steel against chloride ingress because it is more tolerant to chloride, requiring a higher concentration for depassivation and it corrodes more slowly in chloride-contaminated conditions.
