What Industries Encompass the U.S. Primary Metals Sector?
Primary metal manufacturers smelt or refine metals. These companies work with both ferrous (iron) and nonferrous types. They refine them from ore, pig iron, and scrap metal. If you were to tour the production facilities, you would find processes based on the use of electricity, chemicals, or both. These manufacturers also make alloys composed of various combinations of metals.
The initial products are ingots, the type of shapes you might picture being stored at Fort Knox. Ingots can be drawn, rolled, or extruded into other forms, including:
- Sheets.
- Strips.
- Bars
- Rods.
- Wire.
Ingots can also be melted to make castings. Other manufacturers fabricate an almost unlimited array of products from these basic forms.
By SIC category, the industry breaks down as follows:
- Steel Works, Blast Furnaces & Rolling Mills (SIC 331): 2,288 companies (38.6%)
- Nonferrous Foundries (SIC 336): 859 companies (14.5%)
- Nonferrous Rolling & Drawing (SIC 335): 856 companies (14.5%)
- Miscellaneous Primary Metal Products (SIC 339): 660 companies (11.2%)
- Secondary Nonferrous Metals (SIC 334): 593 companies (10.0%)
- Iron & Steel Foundries (SIC 332): 506 companies (8.6%)
- Primary Nonferrous Metals (SIC 333): 159 companies (2.7%)
Steelmaking remains the largest single segment, but nonferrous metals, including lightweight alloys for aerospace to copper for clean energy grids. represent a fast-growing share of the market.
Where Metal Manufacturers Are Located
Primary metals manufacturing is deeply regional. The Midwest continues to lead with 38% of companies, followed by the South (30%), the East Coast (18%), and the Pacific/Mountain region (14%).
Top States for Metals Manufacturing
1. Ohio – 935 companies (10.7%)
Ohio has long been the heart of American steel and foundry production. Its position along the Great Lakes provides efficient shipping of raw materials and finished products, while its proximity to Detroit and Chicago makes it indispensable to the automotive supply chain. Ohio is also home to a strong cluster of pipe and tube manufacturers, supporting energy infrastructure.
2. Pennsylvania – 713 companies (8.2%)
Pennsylvania is synonymous with steel. Pittsburgh remains a global symbol of heavy industry, while eastern Pennsylvania specializes in copper, specialty steels, and advanced alloys. The state’s intermodal transport system—rail, highways, and ports—keeps its producers well-connected to domestic and export markets.
3. Texas – 636 companies (7.4%)
Texas’s role in the primary metals sector is tied to energy. Houston is a hub for pipe and tube manufacturing, while Dallas and San Antonio house a mix of steel and aluminum producers serving construction and petrochemical markets.
