Class 2423 - Non-ferrous Rolling, Drawing and Extrusion Mills

Class 2423 sits in the PSIC 2019 hierarchy under C Manufacturing > 24 MANUFACTURE OF BASIC METALS 'This division includes the activities of smelting and/or refining ferrous and non- ferrous metals from ore, pig or scrap, using electrometallurgic and other process metallurgic techniques. This division also includes the manufacture of metal alloys and super-alloys by introducing other chemical elements to pure metals. The output of smelting and refining, usually in ingot form, is used in rolling, drawing and extruding operations to make products, such as plate, sheet, strip, bars, rods, wire, tubes, pipes and hollow profiles, and in molten form to make castings and other basic metal products. > 242 Manufacture of basic precious and other non-ferrous metals. This class usually fans out into more specific subclasses such as Non-ferrous Rolling, Drawing and Extrusion Mills. It is the level people use when they already know the activity family but still need the exact five-digit match.
