Choose the Correct Armco Grade There is a grade of Armco sheet metal particularly suited to every air conditioning application. For detailed information get in touch with the nearest district office or write direct to The American Rolling Mill Company, Middletown, Ohio. Armco Ingot Iron (Galvanized) Ducts Washer Chambers Plenum Chambers Steam Line Casings Furnace Casings Spray Towers Drip Pans / Housings Machine Guards Unit Conditioners Roof Ventilators Eliminator Blades Armco PAINTGRIP (Galvanized) A special mill-Bonderized galvanized sheet that can be painted without pre treatment. Preserves life and beauty of paint. Armco Cold Rolled Paintgrip: A zincflashed sheet with a special mill-Bonderized surface. Hot Rolled (Sheets and Strip) Fan Blades Blower Casings Fuel Oil Tanks Unit Conditioners Stoker Hoppers Armco ZINCGRIP A special zinc-coated sheet that can be severely formed without peeling or flaking of the tightly adherent zinc coating. Also available with a Paintgrip finish. Cold Rolled (Sheets and Strip) Furnace Casings Room Unit Casings Plates (ARMCO Ingot Iron) Smoke Stacks Coal Hoppers Breeching Unfired Pressure Vessels Low-fired Boilers Tanks High Strength Steel A low alloy, high tensile steel possessing great strength. Used with'proper design it results in weight reduction of frame work, tanks and similar items. Under atmospheric service conditions it. has cor rosion resistance superior to regular steel Stainless Steel (Sheets, Strip and Plate) Combustion Chambers Heat Flues and Tubes Humidifier Pans Pre-heaters Furnace Parts and Supports Fan and Blower Blades Special grades have excellent resistance to destructive heat-scaling up to 2000 F. Armco ALUMINIZED Steel An aluminum-coated sheet steel with exceptional resistance to heat and corrosion. Resists heat discoloration up to approximately 900 F., and will withstand oxidation at even higher temperatures. Also offers exceptional heat reflectivity where this is desirable. 984 '-i :a J) I Air System Equipment Sheet Metal and Tubular Products BETHLEHEM STEEL COMPANY GENEBAL OFFICES: BETHLEHEM, PA.

Syracuse Toledo Tulsa Washington Wilkes-Barre York Export Distributors Bethlehem Steel Export Corporation, New York BETHLEHEM PRODUCTS FOR HEATING, VENTILATING AND AIR CONDITIONING Steel Sheets--Bethlehem manufactures a line of sheet steel to handle all types of heating, ventilating and air-conditioning jobs. Sheets are produced in the general classifications of hot-rolled (black); coldrolled, and galvanized. Hot-rolled sheets are made in thicknesses from No. 18 gage to No. 2 gage, in widths varying with the thicknesses. Cold-rolled sheets are made in widths over 12 in. and in gages No. 11 to 30 inclusive. Galvanized sheets are made in gages 8 to 31 inclusive in widths of 24, 30, 36, 42 and 48 inches. Especially well-suited for heating and ventilating ductwork are rust-resisting Beth-Cu-Loy copper-bearing sheets. Thor ough going tests have proved that the 0.20 to 0.30 per cent of copper in these sheets will double or nearly triple their rust re sistance. Thus they rank high in this respect among commercial grades of iron and steel sheets. Galvanized sheets of Beth-Cu-Loy form and seam readily, and the extra cost is only four to five per cent. Steel Pipe--Bethlehem now produces a strong butt-welded pipe, known as Beth-Co-Weld, in sizes from 3^-inch diameter to 3-inch, inclusive, and in uni form 21-foot lengths, plus or minus one inch. This pipe is uniform in size, length, and physical characteristics. It will do a consistently good job wherever used. Ammonoduct, a steel pipe which can be bent cold without annealing or danger of fracture, has long been a Bethlehem specialty. Unusually soft and ductile because it is made of a special quality open-hearth steel, Ammonoduct is easy to fabricate. Made in sizes from J^-inch diameter to 3-inch, inclusive, standard weight and extra strong, and in long lengths. In peacetime it was used ex tensively for ammonia piping, heater coils, water legs in furnaces and similar uses where pipe must be bent. Ammonoduct is ideal for radiant-heating installations. Will be available in quantity after the war emergency is over. If you have a contract for heating, ventilating or air-conditioning, use de pendable Bethlehem materials. Sted from this giant mill vriU eventually become Bethlehem sheets. 985 Here's how the rolls of our modern mill form Beth-Co-Wdd Pipe.
