Excerpt
Excerpt: The Primary Metal Manufacturing industries are well defined and include the production of steel and steel products; the smelting, refining, and rolling of nonferrous metals; and the production of metal castings. The processes employed in these industries include the use of blast furnaces to produce iron, and the use of basic oxygen and other steel making furnaces to produce steel. Rolling, drawing, and extruding processes to produce such products as pipe and tube, wire, and sheet are also used in this subsector. Similar processes are used to produce the nonferrous metal and metal products also included in this subsector. A structure along the lines of function or process (refining and smelting, or rolling, drawing, and extruding) for all metals was considered for this subsector. It was not adopted, because: (1) the processes, although they have some similarity, are clearly distinct for steel versus nonferrous metals. Within nonferrous metal manufacturing, the processes are also different. For example, the primary reduction of aluminum involves the massive use of electricity, where the primary reduction of copper is accomplished by using heat and chemicals; (2) establishments that roll, draw or extrude are highly specialized by type of nonferrous metal; (3) due to the combination of process activities in aluminum manufacture in Mexico, a separate trilateral NAICS industry could not be created that would split primary aluminum from aluminum, rolling, drawing, and extrusion. For this reason, a separate NAICS 3-digit and 4-digit industry group and industry was created for Smelting, Refining, Rolling, Drawing and Extruding Aluminum, and a 3-digit NAICS group, Smelting, Refining, Rolling, Drawing, and Extruding of Other Nonferrous Metal, that parallels the 3-digit structure for Aluminum. The ?Other? nonferrous group, however, contains 4-digit levels for process industries for copper and for nonferrous metals, except aluminum and copper.
