WebGalvanized Vs Powder Coated: Cost & Other Clear Differences. So how are hot-dip galvanizing and powder coating different? Hot-dip galvanizing — where the metal component is thoroughly cleaned and prepped then dipped in molten zinc — has its perks. For example, it forms a thick, protective layer that can last 100 years. WebJul 18, 2024 · Comparison. Cold-rolling and galvanization are not mutually exclusive, and in fact cold-rolled steel can be galvanized. That's because cold-rolling is a technique for forming the steel, whereas HDG is a technique for treating it to protect it from corrosion. Galvanized steel generally has much better corrosion resistance, although it's less ...
