The initial release of zinc and aluminum from non-treated Galvalume and the formation of corrosion products in chloride containing media

► Emphasis on short- and long-term corrosion and release processes for Galvalume. ► Close relation between corrosion product formation and release patterns. ► Selective release of zinc over aluminum in chloride-rich environments. ► Zinc and aluminum rich corrosion products predominantly formed in interdendritic areas.
