TY - JOUR AB - TWO‐YEAR atmospheric exposure tests of a number of sheet metals used in building construction have recently been completed by the U.S. National Bureau of Standards. Sheets of aluminium and zinc alloys and of aluminium‐coated and galvanised steel were exposed to the weather under conditions closely approximating those found in actual practice. Each metal tested was fastened to bare wooden boards with nails of various materials, both with and without neoprene or lead sealing washers between the nail head and the sheet. The study was conducted by T. H. Orem of the Bureau's corrosion laboratory.
