Creating solutions for our team, customers, suppliers and other stakeholders.

About Us

Steel Dynamics was founded in 1993 by three steel industry veterans—Keith Busse, Mark Millett and Dick Teets—who shared a vision and a plan to create a company that would produce the highest-quality steel in the most efficient, cost-effective manner possible.

Since that time, our company has grown both organically and through acquisitions to become the fourth-largest producer of carbon steel in the United States at its seven primary steel mills.

Steel Dynamics Operations

Steel Dynamics is comprised of its Flat Roll Group that produces various flat roll products as, well as its Long Products Group that produces structural shapes, specialty shapes, rail, engineered- and merchant-bar products.

In addition to the Flat Roll Group and Long Products Group, Steel Dynamics includes OmniSource, an extensive metals-procurement and recycling division and New Millennium Building Systems which produces steel joist and deck products.

Steelmaking Industry

Our rapid climb in the steelmaking industry began with the construction of a greenfield mini-mill—now the Flat Roll Group campus—near the small town of Butler in northeast Indiana. In a fashion that has become emblematic of all our endeavors, the mill was built in record time. Phase I, which included facilities and equipment sufficient to establish a 1.2 million-ton annual capacity, was completed in a record 13 months—from groundbreaking to the start of production.

Production of hot rolled steel began early in 1996, followed by the addition of a cold mill in late 1997. In the summer of 1998, further expansion pushed the mill’s annual capacity to 2.2 million tons. In 2003, we added a coil-coating line to the flat roll campus with the capacity to paint 300,000 tons of steel annually.

Butler Division Growth

In 2003, we acquired the former GalvPro facility in Jeffersonville, Indiana. This was an addition to the Butler downstream assets that specialized in finishing thinner-gauge steel. Jeffersonville has the capacity to coat 300,000 to 350,000 tons annually of cold rolled steel produced at Butler and has the capacity to paint 190,000 tons annually on its state-of-the-art coil-coating line.

In 2009, we achieved an annual production capacity of 3 million tons at the Butler flat-roll mill, a goal we’d had in our sights since startup.

In 2013 and 2016, we added a Leveling Line and a Push Pull Pickle Line with shape enhancement at the facility in Butler to enhance our value-added services and meet our customers’ changing demands.
