Primary metal manufacturing
331 - Primary metal manufacturing
This subsector comprises establishments primarily engaged in smelting and refining ferrous and non-ferrous metals from ore, pig or scrap in blast or electric furnaces. Metal alloys are made with the introduction of other chemical elements. The output of smelting and refining, usually in ingot form, is used in rolling and drawing operations to produce sheet, strip, bars, rods and wire, and in molten form to produce castings and other basic metal products.
Exclusion(s)
- manufacturing metal forgings or stampings(332)
3315 - Foundries
This industry group comprises establishments primarily engaged in pouring molten metal into moulds or dies to form castings.
Exclusion(s)
- forging and stamping metal(3321)
33151 - Ferrous metal foundries
This industry comprises establishments primarily engaged in pouring molten iron or steel into moulds to produce castings. These establishments generally operate on a job order basis, manufacturing castings for sale or transfer to other establishments.
