Hot-dip galvanized (HDG) steel is specified because it provides maintenance-free corrosion protection for decades. However, some architects and engineers under utilize HDG because of concerns about its appearance. Due to steel chemistry, fabrication processes, and other factors, the initial appearance of hot-dip galvanized steel can vary from bright and shiny to matte gray, or a mixture of both.

Hot-dip galvanizing of steel structuresHot - Dip Galvanizing of Steel Structures. Hot dip galvanizing is a process of immersion of a steel structure in a bath with a 450-degree Celsium zinc melt.. After the structure is removed, an oxide-carbonate film is formed on the zinc-coated surface, this is a protective layer, which protects from further oxidation.
Dec 01, 2020 · During hot dip galvanizing, the layer of zinc is metallurgically bonded to the base metal. The metallurgically bond may directly affect the crack initiation in structural steel elements withstanding high level of fatigue loads as well as a large number of load cycles, thus affecting their fatigue behaviour.
