COPPER-BEARING BETH-CU-LOY FOR RUST RESISTANCE The charts at the right show conclusively the superior rust resistance of copperbearing steel. Sheets of the same com position as Beth-Cu-Loy, Bethlehem's copper-bearing steel, outlasted ordinary iron and steel by a wide margin when exposed to atmospheric corrosion. Beth-Cu-Loy, available in the form of sheets, pipe and plates, offers 2 to 3 times longer life as indicated by these three corrosion tests--and Beth-Cu-Loy costs only 3 to 5 per cent more than ordinary steel, much less than open-hearth orcopper bearing iron. Heating, ventilating and air conditioning engineers, architects and contractors are finding it pays to specify Beth-Cu-Loy wherever moisture or corrosion is a factor. Beth-Cu-Loy sheets are easily workable, durable and low in cost. A.S.T.M.

T-Af.--Committee A-5, Vol. 38). No failures in copper-bearing steel sheets at last report. BETHLEHEM MAKES: Sheet Steel -- all grades, hot-rolled (black), cold-rolled, and galvanized-- available in Beth-Cu-Loy. Steel Pipe--In sizes up to 3 inches, now made by the Continuous-Weld Process and sold under the trade name Beth-Co-Weld. Ammonoduct--A new kind of pipe that has an outstanding advantage in its unusual ductility. It can be bent cold, without need for annealing, without danger of fracturing. Recommended for ammonia piping and for heater coils, water legs in furnaces and similar uses where pipe must be bent.
