This manual was prepared to provide architects and specifiers with a reliable reference for the proper design and installation of architectural sheet metal. This third edition contains many changes in fastening methods, support methods, and metal forming style. Several alternative methods of design and installation are displayed for many items in the manual, to give the architect choice in the application and to reflect area practices and varying climatic conditions throughout the country. A valuable resource.
