I want to know too!!
Dear Karen, Galvanic (zinc) coat will work as anode and will corrode instead of the cathode (Metal). You need coated anchor and plate if they are exposed to moisture, sulfates, chlorides, alkalies, or combination of them to guard against corrosion. You can use Stainless steel anchor and plates or other cathodic protection methods based on your outdoor exposure condition.
