FactoryRegistry lists 10,076 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 structural block, lightweight units (units made with concrete weighing less than 105 lb per cubic foot) (dry weight), 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.
