History of Steel Dynamics
- Founded: 1993
- Founders: Keith Busse, Mark Millett, Richard Teets
The brand launched with the company's 1993 founding by three former Nucor executives, and its first product, Butler, Indiana flat-rolled steel in 1996, established the low-cost EAF reputation it still holds.
Product names accumulated as the company expanded: OmniSource for the scrap platform acquired in 2007, New Millennium Building Systems for joist and deck, and the SDI Biocarbon and aluminum lines launched in the 2020s. The aluminum venture made the brand multi-metal for the first time when it achieved positive EBITDA in December 2025.

Steel Dynamics Sustainability & Ethics
The brand's sustainability claim is structural: electric arc furnaces melting recycled scrap produce steel at a fraction of the emissions of coal-based integrated mills. Biocarbon extends that story into reductants. Corporate reporting covers safety, emissions intensity, and recycled content.
Steel Dynamics Recalls & Controversies
Controversies are operational rather than brand-level: environmental permit matters at mills and scrap yards, periodic OSHA citations, and non-union labor relations that have drawn organizing efforts. No consumer-facing recalls apply to industrial steel products.
