FactoryRegistry lists 990 facilities whose primary industry classification is one of the 2 industries above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced cast iron, aluminum, and other nonferrous metal boilers, radiators, and convectors, including baseboard, finned tube, residential, and special types (excluding electric, automotive, and parts), 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.
