FactoryRegistry lists 1,012 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 ductile iron castings for all other uses, including valve, construction and utility, machinery, electric and electronic equipment, heat-resistant parts (including coke oven doors), 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.
