Businesses in the metals and metal ores category supply, trade or process metallic raw materials for manufacturers, construction firms, foundries and other industrial customers. Products may include iron and steel, aluminium, copper, lead, zinc, nickel and other non-ferrous metals, as well as ores and concentrates containing metals for further processing. Some businesses specialise in particular metals or grades, while others handle a broad range of materials. Supplies are commonly provided as sheets, plates, bars, rods, sections, tubes, coils, ingots, powders or bulk mineral loads. Depending on the business, services can include sourcing and importing, sorting and grading, cutting or other preparation to specified dimensions, materials testing, storage and delivery. Metal merchants and processors may also handle recyclable metal, separating and preparing it for reuse.
