A strip product consists of a metallic substrate, such as stainless steel, and a coating, which in turn comprises at least one metallic layer and one reactive layer. The coated strip product is produced by providing the different layers, preferably by coating, and thereafter oxidizing the coating to accomplish a conductive surface layer comprising perovskite and/or spinel structure.
