Copper Steel has 2 to 3 times the atmos pheric corrosion resistance of plain steel or pure iron as shown in the results of un biased tests. made at Pittsburgh, Ft. Sheridan and Annapolis by the American Society for Testing Materials. The cost of U'S'S Copper Steel is less than that of pure iron or copper-bearing pure iron and only slightly more than plain steel. Thus there often is a dividend of 200 per cent to 300 per cent longer life and a saving in the first cost as well. When galvanized, U'S'S Copper Steel produces a sheet that is rust resistant all the way through--not just on the surface. It should be used for all ducts carrying humidified air or placed in damp locations such as basements, shower rooms, etc. USS PAINTBOND U S S PaintBond should be used whenever galvanized steel is to be painted.
