In this work, the type and level of strain are related to the degree of corrosion resistance and the type of coating damage for three coatings: 40 gm/m2 electrogalvanized steel, 80 gm/m2 electrogalvanized steel and Zincroplex™, a zinc-rich paint over 40 gm/m2 electrogalvanized steel. The coating weight of the electrogalvanized steels was a factor in the degree of coating damage and thus affected corrosion resistance. The electrogalvanized steels were adversely affected by bi-axial deformation. Zincroplex™ failed under draw-type deformation. Although the corrosion limit diagram technique does not predict service life, it can distinguish among the capabilities of different materials at different levels and types of strain.
