Who makes it
5 companies produce galvalume / galvanized steel coil.
Australian flat-steel maker; owns BIEC International (global Galvalume/Zincalume licensor) and NS BlueScope (US Steelscape coil, Asia COLORBOND). Controls the Galvalume trademark and process licensing worldwide.
Integrated steelmaker; flat-rolled hot-dip galvanized, Galvalume and pre-painted (PPGI) coated sheet. Acquired by Nippon Steel in 2025.

Key plate facilities: Burns Harbor, Indiana (carbon/HSLA plate + heat treating); Gary, Indiana (same grade mix); Coatesville, Pennsylvania (EAF-based, 800,000 tons/year, 450+ steel chemistries including military alloy, quench-and-temper capability). Also serves automotive as AK Steel legacy. The Coatesville PA facility is one of the most technically capable US plate mills — produces complex alloys including military armor plate. Iron ore mining operations in Minnesota/Michigan (Minorca Mine, Tilden Mine, Empire Mine) provide integrated raw material supply from Great Lakes region.

Products: carbon, HSLA, alloy, and pressure vessel-quality steel plate. Markets served include heavy equipment, dump bodies, on-highway trucks, rail cars, barges, ships — fire apparatus structural steel falls in this category. Buy America compliance: all domestic EAF production qualifies. Nucor also owns David J. Joseph (scrap procurement) and various downstream fabricators. Largest US recycled-content steel producer.
