This article presents the results of accelerated tests conducted to determine the durability of steel sheets in a salt spray environment. Steel sheets, protected against environmental impacts using various technologies and then cold-formed, were selected for the tests. It was demonstrated that the most important problem to solve to achieve satisfactory corrosion resistance is achieving dimensional stability of the galvanic coating. Sheet samples containing multiple layers, i.e., polymer and galvanic coatings, were characterized by smaller mass changes due to exposure to corrosive conditions. In these cases, corrosion initiation occurred more readily in areas where the thickness of the galvanic coating varied, as observed in the cross-sections of the sheet metal.
