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.

by Robert Dahlstrom, Apellix; and Michael Hindmarsh, AkzoNobel Cleaning, coating and nondestructive testing at industrial sites requires extensive manual labor, often at heights, and drones can be used to perform some of these tasks while keeping workers safely on the ground. The authors discuss how nondestructive measurement drone capabilities have evolved over the past few years and offer a preview of cleaning and coating drone systems that are currently under development.
