What’s the difference between galvanized steel and stainless steel?

The difference between galvanized steel and stainless steel comes down to composition. Galvanized steel is steel that features a zinc coating, which helps to create a barrier between the steel and the air and moisture, protecting it from rust. Stainless steel is steel that is mixed with at least 10% chromium to create an alloy that is corrosion-resistant, as well as bacteria-resistant. Stainless steel is ultimately the more durable option.
