Manufacturing of nonclay refractories, including magnesite and magnesite chrome brick and shapes, refractory mortars and ramming mixes, and plastic refractories (excluding dead-burned magnesia)
FactoryRegistry lists 588 facilities whose primary industry classification is one of the 1 industry above. This is a list by industry, not a list of makers: Census reports that establishments in these industries produced nonclay refractories, including magnesite and magnesite chrome brick and shapes, refractory mortars and ramming mixes, and plastic refractories (excluding dead-burned magnesia), 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.
The U.S. Census Bureau recorded this product line in 1 US manufacturing industry in the 2022 Economic Census, as the most specific line that industry reported, and withheld the establishment count for it.
These are counts of establishments by industry: the Economic Census publishes them as industry totals and never as a list of plants.
