Nucor s steel mills in Auburn, N.Y. and Crawfordsville, Ind supply the majority of the raw materials for this plant. The Nucor Corporation is one of the largest steel producers and recyclers of steel products in the United States. Nucor's origins are with auto manufacturer Ransom E. Olds, who founded Oldsmobile and then Reo Motor Cars. Through a series of transactions, the company Olds founded eventually became the Nuclear Corporation of America. In 1972, the company adopted the name Nucor Corporation. Since that time, Nucor has built more Vulcraft facilities and steel mills, and has expanded into other steel products.
