Steel Dynamics, Inc.

A maker of steel and metals-recycling services, Steel Dynamics melts down recycled scrap in electric arc furnaces to produce everything from beams and rail to coated sheet steel, used in construction, autos, and heavy equipment. Founded in 1993 by three former Nucor executives in Fort Wayne, Indiana, it grew into one of the largest steel producers in the US. Fun fact: because its mills run on recycled scrap, the company even bought its own scrap processor, OmniSource, to feed its furnaces with a steady supply of old metal.
