THE STEEL CYCLE

  1. Unprocessed Ferrous Scrap — Steel trimmings and cut-offs enter the scrap cycle as industrial scrap, by-products of steel stamping or forming operations. Old automobiles, appliances, farm and office equipment, buildings, bridges, and other goods containing steel enter the scrap cycle as obsolete scrap.
  2. Processed Ferrous Scrap — Steel scrap is sorted for processing, where it is cut (using a shredder, shear, or torch) or baled (using a large baling press). Once in a more compact form, the scrap is shipped to electric furnace mini-mills or integrated steel mills.
  3. Semi-Finished Steel — Steel mills melt ferrous scrap, add alloys to adjust its chemistry, and then cast the molten steel into slabs or billets.
  4. Finished Steel — Hot slabs or billets pass through rolling mills to form steel coils, wide-flange beams, rail, bars, rebar, and other finished steel products.
  5. Steel Products — Finished steel undergoes additional processing or is shipped directly to the end user, where it is used in the production of new automobiles, appliances, farm and office equipment, buildings, bridges, and other products.
