Valmont Coatings provides a deglaring application to galvanized utility poles and transmission structures. The deglaring process reduces the reflectivity of the galvanizing and enables the structure to blend more comfortably into wooded and arid environments.
During the process, the structure is immersed in a bath containing a zinc-phosphate solution. While immersed, insoluble zinc-phosphate crystals are precipitated and deposited on the surface of the galvanized coating. After allowing the reaction to take place for some time, this crystallizing action leaves behind a continuous film of zinc-phosphate on the surface of the galvanized structure. After the desired zinc phosphate film weight is deposited, the structure is removed from contact with the zinc-phosphate solution and then rinsed thoroughly and dried.
