Hot-dip galvanized steel is produced by immersing fabricated steel in molten zinc at approximately 450°C. This process creates a series of iron-zinc alloy layers covered by a pure zinc outer layer. The result is a tough, adherent coating that provides both barrier and cathodic protection. Unlike paint, the galvanized coating bonds metallurgically to the steel, meaning it will not peel or delaminate. This proven process delivers reliable, long-term corrosion protection for steel products.
