Galfan is an advanced hot-dip coating composed of approximately 5% aluminum and 95% zinc, offering significantly enhanced corrosion protection compared to standard galvanized steel. This alloy coating provides roughly twice the corrosion resistance of conventional zinc galvanizing, making it particularly suited for demanding outdoor and industrial environments. The unique metallurgical properties of the Galfan coating also provide superior flexibility, allowing the coated steel to undergo high-draw forming operations without cracking or flaking of the protective layer.
