Concrete Block and Brick Manufacturing

This includes establishments primarily engaged in manufacturing concrete block and brick.

Iron and Steel Mills and Ferroalloy Manufacturing

Establishments in this category are primarly engaged in one or more of the following: (1) direct reduction of iron ore; (2) manufacturing pig iron in molten or solid form; (3) converting pig iron into steel; (4) making steel; (5) making steel and manufacturing shapes (e.g., bar, plate, rod, sheet, strip, wire); (6) making steel and forming pipe and tube; and (7) manufacturing electrometallurgical ferroalloys. Ferroalloys add critical elements, such as silicon and manganese for carbon steel and chromium, vanadium, tungsten, titanium, and molybdenum for low- and high-alloy metals. Ferroalloys include iron-rich alloys and more pure forms of elements added during the steel manufacturing process that alter or improve the characteristics of the metal.

Nonferrous Metal (except Aluminum) Smelting and Refining

Establishments in this category are primarly engaged in (1) smelting ores into nonferrous metals and/or (2) the primary refining of nonferrous metals (except aluminum) by electrolytic methods or other processes.

Nonferrous Metal (except Copper and Aluminum) Rolling, Drawing, and Extruding

This includes establishments primarily engaged in (1) rolling, drawing, or extruding shapes (e.g., bar, plate, sheet, strip, tube) from purchased nonferrous metals and/or (2) recovering nonferrous metals from scrap and rolling, drawing, and/or extruding shapes (e.g., bar, plate, sheet, strip, tube) in integrated mills.

Secondary Smelting, Refining, and Alloying of Nonferrous Metal (except Copper and Aluminum)

This includes establishments primarily engaged in (1) alloying purchased nonferrous metals and/or (2) recovering nonferrous metals from scrap. Establishments in this industry make primary forms (e.g., bar, billet, bloom, cake, ingot, slab, slug, wire) using smelting or refining processes.

Nonferrous Forging

This includes establishments primarily engaged in manufacturing nonferrous forgings from purchased nonferrous metals by hammering mill shapes. Establishments making nonferrous forgings and further manufacturing (e.g., machining, assembling) a specific manufactured product are classified in the industry of the finished product. Nonferrous forging establishments may perform surface finishing operations, such as cleaning and deburring, on the forgings they manufacture.

Custom Roll Forming

This includes establishments primarily engaged in custom roll forming metal products by use of rotary motion of rolls with various contours to bend or shape the products.

Sheet Metal Work Manufacturing

This includes establishments primarily engaged in manufacturing sheet metal work (except stampings).

Other Metal Container Manufacturing

This includes establishments primarily engaged in manufacturing metal (light gauge) containers (except cans).

Illustrative Examples:

Light gauge metal bins manufacturing
Light gauge metal drums manufacturing
Light gauge metal garbage cans manufacturing
Light gauge metal lunch boxes manufacturing
Light gauge metal mailboxes manufacturing
Light gauge metal tool boxes manufacturing
Light gauge metal vats manufacturing
Metal air cargo containers manufacturing
Metal barrels manufacturing
Vacuum bottles and jugs manufacturing

Analytical Laboratory Instrument Manufacturing

This includes establishments primarily engaged in manufacturing instruments and instrumentation systems for laboratory analysis of the chemical or physical composition or concentration of samples of solid, fluid, gaseous, or composite material.
