GDS-Series Spectroscopv Performance Note QDP Analysis ofGalvanized Stee ·Galvanizing Thickness and Coating Weight ·Composition on the Coating and Substrate ·Surface Treatments The application of zinc and zinc-alloy coatings to steel provides both galvanic and barrier corrosionprotection. Galvanized coatings can be applied by either continuous hot-dip coating or electroplating.Hot-dip coatings include galvanized (zinc), galvannealed, Al-Zn with 55% aluminum and Zn-Al with 5%aluminum. Electroplated coat)iantgs include zinc and Zn-Ni. The choice of coating depends on theapplication. Thin coatings provide sufficient corrosion resistance where the corrosion rate is low, such asinterior panels and painted parts. Thick coatings are needed where corrosion rate is high and longservice life is required, such as marine or underground applications. The analysis conforms to and is inaccordance with ISO 16962.
