Galvanized Coating Removal American Welding Society
Mar 06, 2006· This ends up not only costing alot of acetylene, but also burning a hole in the ozone above the shop. I was curious to see if anyone knows any methods of soaking galvanized/zinc coated steel in solutions that will dissolve the coating, or something effective. I would order it online, but then again, chain is heavy and shipping might be a bitch.
