Steel Dynamics, Inc. is unique among American steel companies. It is one of the youngest of America's major steel companies. It quickly grew to become one of the premier carbon steel producers in the United States. Steel Dynamics' historic growth is a combination of organic capacity greenfield additions and strategic acquisitions. By adding upstream assets that provide raw materials needed to produce high quality steel at each of its mills, and bridging downstream assets that fabricate a variety of high quality steel products, Steel Dynamics has both broadened its product portfolio and expanded its market diversity. As the company's steelmaking capacity grew and it introduced new products to the market, the company began delivering strong earnings.
