Nucor Corporation is a leading American steel manufacturer based in Charlotte, North Carolina. It holds the distinction of being the largest steel producer and scrap recycler across North America and is ranked as the 16th-largest steel manufacturer worldwide. Together with Commercial Metals Company, Nucor serves as a key provider of rebar utilized in infrastructure development projects throughout the United States.

Current operations

Nucor utilizes electric arc furnaces combined with continuous casting methods to process scrap steel, foregoing the use of conventional blast furnace techniques. In 2024, the company produced and marketed approximately 18.5 million tons of steel while recycling 18 million tons of scrap metal. Notably, none of its production facilities are unionized, reflecting the company’s stance against trade union involvement.

History

Following the dissolution of REO Motor Car Company, activist investors transformed the enterprise through a reverse merger with Nuclear Consultants, Inc., subsequently renaming it "Nuclear Corporation of America Inc." The firm initially sought to enter the nuclear services sector but shifted focus after unsuccessful attempts. It evolved into a diversified conglomerate by acquiring Vulcraft Corporation, a steel joist manufacturer located in South Carolina.

In 1962, Vulcraft was acquired, and F. Kenneth Iverson was appointed general manager. After filing for bankruptcy in 1965, Iverson assumed leadership and restructured the company around Vulcraft’s core operations, divesting other divisions. The corporate headquarters relocated to Charlotte in 1966 to be closer to Vulcraft’s primary manufacturing facility.

By 1968, Iverson advanced into steel production by establishing a steel bar mill in Darlington, South Carolina, utilizing an electric arc furnace funded by a $6 million loan secured against company assets. Despite early difficulties, the company experienced significant profit growth during the early 1970s.

The organization adopted the name Nucor Corporation in 1972 and conducted its initial public offering that same year. In 1988, it introduced its building products division.

In 1989, Nucor inaugurated its Crawfordsville, Indiana plant—the first mini mill globally to produce flat rolled steel using thin-slab technology.

In March 2000, Nucor formed a joint venture with BlueScope and IHI Corporation to license Castrip technology, which enables continuous casting of sheet steel directly from molten metal without employing heavy rollers.

Environmental Matters

In 2000, Nucor committed to investing $98 million to address concerns raised by the United States Department of Justice and the United States Environmental Protection Agency (EPA) over insufficient control of hazardous emissions across several states. This sum included $85 million allocated for updated air pollution control technology, $4 million dedicated to community pollution monitoring initiatives, and a $9 million civil penalty. At that time, this agreement represented the most significant environmental settlement involving a steel producer.

In 2016, Nucor contested an EPA proposal aimed at regulating visible emissions in Arkansas, but the challenge was unsuccessful.

By 2023, Nucor had entered a partnership with ExxonMobil to develop a carbon capture and storage initiative capable of sequestering up to 800,000 metric tons from its direct reduced iron facility situated in Convent, Louisiana, a site previously noted for emission compliance issues.
