There is certain percentage of people,allergic to ingredients(nickel) included in some s.steels.A few weeks ago I've got this reaction while putting my bare feet on galvanized bar stool(!).Sweat dissolved minimal amount of it and poor me had sore blisters for over 1 week...You never know,what's gonna itch you 'till is too late.Anyway,if is it ,,common" (understand ,,cheap")sheet metal,used for sinks and other stuff,it SHOULD be OK.
