In order to examine the performance of repaired painting on steel plates with four types of deteriorated metallic coating systems, acid rain combined cyclic corrosion tests were performed. The four types of metallic coating systems were zinc hot dip galvanized coating, zinc-aluminum alloy coating, zinc-aluminum pseudoalloy coating and aluminum coating. The effect of remaining thickness of metallic coating on the performance of repair paint was discussed. Finally, the lifecycle cost analysis was performed for various repair strategies for the four types of metallic coating systems.},
