Manufacturing of sheet metal air-conditioning ducts (including dust collection ducts), stove pipe, furnace smoke pipe, and elbows
NAPCS COLLECTION CODE 2038675000
The U.S. Census Bureau recorded this product line in 3 US manufacturing industries in the 2022 Economic Census, as the most specific line those industries reported. At least 667 establishments reported producing it; the count for 1 of those industries was withheld.
That is a count of establishments by industry. It says how many establishments in each industry reported this product line; the Economic Census publishes these figures as industry totals and never as a list of plants. The largest share Census published for any one industry is 13.8% of that industry’s establishments.
Withheld means Census suppressed the figure because publishing it would disclose an individual establishment. The line itself is never suppressed — only the numbers on it.
Facilities in those industries
FactoryRegistry lists 10,051 facilities whose primary industry classification is one of the 3 industries above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced sheet metal air-conditioning ducts (including dust collection ducts), stove pipe, furnace smoke pipe, and elbows, 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.
