Steel Dynamics, Inc. (SDI) is a steel producer based in Fort Wayne, Indiana[1] and the fifth largest producer of carbon steel products in United States. Over sixty percent of the company’s steel shipments are flat-rolled sheet steel and the remainder is "long products" (bars and beams) and fabricated products. SDI is among the most profitable American steel companies in terms of profit margins and operating profit per ton.

SDI was founded in 1993 and began production at its Butler, Indiana, Flat Roll Mill in 1996. The Flat Roll Division’s finishing facilities at Butler and at Jeffersonville, Indiana, produce pickled, cold-rolled, galvanized, and painted flat-roll steel.

In 2007 SDI acquired The Techs, three hot-dip galvanizing plants in Pittsburgh that coat flat-rolled steel.[citation needed]

In 2007 SDI also acquired OmniSource Corporation.[2]

On July 21, 2014, SDI announced the acquisition of Severstal Columbus, LLC from Russian Severstal for 1.625 billion. The acquisition expands Steel Dynamics' annual steel shipping capacity to 11.0 million tons, representing an approximate 40 percent increase. The additional exposure to the high-growth OCTG and automotive segments complements Steel Dynamics' market offerings. Commissioned in 2007, Columbus is one of the only North American flat roll mills to have 76 inch wide hot roll, 74 inch wide cold roll, and 72 inch wide galvanized sheet capabilities. These and other production capabilities will broaden Steel Dynamics' product portfolio with regard to width, gauge and strength and enhance the Company's position as a leading North American steel producer.
