The spangled appearance of a galvanized coating forms naturally as the zinc cools and forms crystals, with several factors influencing the size and contrast of the pattern. The cooling rate plays a large role in the appearance of spangle, with longer cooling times producing larger and more defined spangle and quick cooling times from quenching causing significantly decreased spangle. Design Considerations for Hot-dip Galvanizing:Dissimilar Weathering steel also can be galvanized, although it typically contains relatively high amounts of silicon and will develop thicker coatings that are usually matte gray in finish. The corrosion protection provided by galvanizing is unaffected by coating appearance. Design considerations courtesy of American Galvanizers Association.

Jul 02, 2018 · Different galvanizers use different additives to the zinc bath such as nickel, bizmuth, aluminum, and tin to change the appearance of a coating and to aid in the types of products that they run in there area. The American Galvanizers Association can help you with some technical question as well as provide literature to explain this a little better. How To Specify Galvanized Steel So That It Looks Good Feb 09, 2012 · The American Galvanizing Association recommends SSPC-SP7 brush-off blast cleaning as the only effective and approved method to remove this coating. The presence or absence of a passivator can be checked using a 3% copper sulfate solution applied to the galvanized metal if the metal discolors, the passivator is either absent or has been removed. Practical Guidelines for the Inspection and Repair of Hot Mar 29, 2019 · Several factors can affects the finish and appearance of hot-dip galvanized coatings. Some of these factors can be controlled by the galvanizers while others cannot. The inspection of finish and appearance is done with an unmagnified visual inspection, which is performed by fully observing all parts and pieces of a hot-dip galvanized product to
nized finish generally is not uniform in appearance. The corrosion protection provided by the galvanized coating, however, is not affected by variation in the color and texture of the coating. After aging in the environment, the entire coating usually ages to a uniform matte gray appearance.
