FactoryRegistry lists 12,255 facilities whose primary industry classification is one of the 5 industries above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced fabricated structural iron and steel, except for construction, in the shares shown above, and does not say which establishments. Where a plant’s own website or a federal registry names what that plant makes, it appears on the plant’s own page with the source named.

The U.S. Census Bureau recorded this product line in 5 US manufacturing industries in the 2022 Economic Census, as the most specific line those industries reported. At least 21 establishments reported producing it; the count for 2 of those industries was withheld.

These are counts of establishments by industry: the Economic Census publishes them as industry totals and never as a list of plants.

NAPCS collection code 2028975000. Source for the product line, the establishment counts and the shares: U.S. Census Bureau, 2022 Economic Census (ECNNAPCSIND2022). Federal source data is public domain. Facility records are compiled separately by FactoryRegistry and carry their own sources.
