Hot-dip galvanized steel sheet in DX51D+Z with spangle finishes for roofing, ducting, enclosures and press-formed parts.
DX51D+Z galvanized steel sheet is continuously hot-dip coated with a zinc layer for sacrificial corrosion protection. The soft DX51D substrate forms and stamps easily, while the zinc coating delivers long service life in atmospheric, indoor and mildly corrosive environments — the most widely used material for building, appliance and general fabrication.
