NAICS 331318 - Other Aluminum Rolling, Drawing, and Extruding
This page includes content generated by AI. It is intended for general guidance only and should be verified for your specific situation.
What is NAICS 331318
NAICS code 331318 covers establishments primarily engaged in the rolling, drawing, and extruding of aluminum shapes, excluding flat rolled sheet, plate, foil, and welded tube products. Businesses in this sector typically process purchased aluminum or recover aluminum from scrap in integrated mills to produce a variety of specialized aluminum products such as bars, rods, tubes, nails, and wire. These firms serve diverse industries including construction, aerospace, automotive, and electronics by providing custom-shaped aluminum components essential for manufacturing and infrastructure projects. Government agencies contract for these services to obtain high-quality aluminum materials that meet strict specifications for durability, weight, and performance in defense, transportation, and public works applications. The ability to source custom-extruded or drawn aluminum shapes supports critical government projects requiring specialized metal components.
