Galvanizing In Action

Capping Corrosion on Bridges with HDG Steel

From JPCL, January 2021

By John Krzywicki, American Galvanizers Association

Hot-dip galvanizing, a process in which steel components are immersed in a molten bath to form a zinc protective coating, has been used for decades in industrial construction to provide a protective layer from corrosive elements. This article will highlight four bridge projects that employed galvanizing—both with and without duplex protective coating systems—to provide long-term, maintenance-free corrosion protection in different service environments....
