Copper Rolling, Drawing, Extruding, and Alloying
NAICS 331420 · United States · 2022 edition
This industry comprises establishments primarily engaged in one or more of the following: (1) recovering copper or copper alloys from scraps; (2) alloying purchased copper; (3) rolling, drawing, or extruding shapes (e.g., bar, plate, sheet, strip, tube, wire) from purchased copper; and (4) recovering copper or copper alloys from scrap and rolling, drawing, or extruding shapes (e.g., bar, plate, sheet, strip, tube, wire).
Start the review with workers' compensation.
For Copper Rolling, Drawing, Extruding, and Alloying, the saved research highlights workers' compensation, commercial property, equipment breakdown. Confirm how these arise in the actual operation, what controls are used and whether additional services change the proposed coverage.
Questions to ask
- What processes are performed on-site — rolling, drawing, extrusion, alloying, scrap recovery, or some combination?
- What are the replacement values for primary production equipment such as furnaces, rolling mills, and extrusion presses?
- Are there any known environmental concerns, prior contamination issues, or regulated waste streams associated with the facility?
- What is the facility's fire suppression system configuration, and when was it last inspected?
- What is the five-year workers' comp loss history, and are there any open claims?
- For Copper Rolling, Drawing, Extruding, and Alloying, what should the underwriter know about significant prior workers' comp losses, particularly severity claims involving crush injuries, burns, or amputation?
- For Copper Rolling, Drawing, Extruding, and Alloying, what should the underwriter know about known or suspected environmental contamination on the premises or adjacent properties?
- For Copper Rolling, Drawing, Extruding, and Alloying, what should the underwriter know about outdated or unsprinklered facilities with high-value process equipment and elevated fire load from combustibles?

Establishments in this class process copper and copper alloys through rolling, drawing, extruding, or alloying operations — converting scrap or purchased copper into forms such as bar, rod, plate, sheet, strip, tube, and wire. Day-to-day operations typically involve high-temperature furnace and annealing processes, heavy machinery, significant scrap material handling, and continuous production lines supplying industrial and manufacturing customers.
