End Markets
Our steel is used in the manufacture of a wide variety of products, including agricultural machinery, automobiles, appliances, construction products, consumer electronics, culverts, grain bins, office furniture, and pipe and tubing. And given the extremely high content of recycled steel used in electric-arc furnace steelmaking, SDI-produced steel is particularly well-suited to applications where conformance to LEED and Green Building guidelines is a consideration.
