FactoryRegistry lists 30,069 facilities whose primary industry classification is one of the 15 industries above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced other sheet metal work (excluding ducts, stove and furnace pipe, steel and aluminum roof ventilators, and steel and aluminum louvers and dampers for heating, ventilation, and air conditioning), 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.
