Dcarch,
Zn + Cu(+2) --> Zn(+2) + Cu Zinc in the galvanized metal will reduce copper in the plus two state to metallic copper. That would be the case with copper sulfate. However, copper sulfide, I dunno. Copper sulfide is very insoluble in water, so I don't know how much would actually be in contact with the galvanized metal.
