SDI says its big bet on aluminum is already paying off at ADI
Written by Stephanie Ritenbaugh
Steel Dynamics Inc. (SDI) leaned into its aluminum operations during its fourth quarter earnings call on Monday, touting progress at its flat-rolled mill in Columbus, Miss. – and hinting at future expansions in aluminum.
“There’s absolutely no doubt that aluminum will be a growth platform for us going forward,” said Mark Millett, co-founder, chairman, and CEO of the Fort Wayne, Ind.-based steel and aluminum maker. “There’s a lot of supply-demand dislocation, so there’s certainly phenomenal opportunities there for us.”
