Which code does this activity belong in?
Code 331318 covers establishments that roll, draw, or extrude aluminum into shapes such as bars, rods, structural shapes, tubes, and wire, whether from purchased aluminum or recovered scrap. The key boundary separates this code from 331315, which covers flat rolling of sheet, plate, foil, and welded tube; establishments producing non-flat shapes belong in 331318. Code 331318 also differs from 331314, which handles the secondary smelting and alloying process that produces ingots and billets before rolling or extrusion; 331318 begins where shaped products are manufactured from these inputs.
