The Evolution of America’s Leading Steelmaker & Recycler


From automobiles to nuclear services to steel, the story of Nucor is about the ability to adapt to changing times. The company’s innovative and teammate-focused culture catapulted Nucor from “the little steel company that could” to the largest steel producer and recycler in America.

1905 – An Unlikely Connection

Ransom E. Olds, creator of the Oldsmobile, forms REO Motor Company, which evolves into the Nuclear Corporation of America and ultimately Nucor.

1962 – Moving Toward The Steel Market

Nuclear Corporation makes two strategic moves that change the company and ultimately the American steel industry: the acquisition of Vulcraft, a producer of steel joists and girders, and the hiring of Ken Iverson to run Vulcraft. Iverson soon emerges as one of the great visionaries and mavericks in American industry.

1964 – Building Something Bigger

The company opens a second Vulcraft plant in Nebraska to meet increasing demand for steel joists. Based on the success of its first two plants, Vulcraft purchases M&S Steel Company of Fort Payne, Alabama in 1967, which becomes Vulcraft – Alabama, and builds its fourth steel joist plant in Grapeland, Texas the following year. Business booms, and Vulcraft’s growth has continued ever since.

1965 – Iverson & Siegel Forge a New Path

Nuclear’s newly appointed president, Ken Iverson, and company treasurer and controller, Sam Siegel, act quickly to put the company on a course toward profitability, including selling off inefficient divisions.

1966 – Steel Resolve

The company moves its corporate headquarters from Phoenix, Arizona, to Charlotte, North Carolina. Iverson proposes entering the steelmaking business and starts a profit sharing program, beginning the company’s tradition of paying for performance.

1969 – Mini Might

The company’s first mini mill, located in Darlington, South Carolina, goes into production. At first intended as a way to provide a reliable and economical supply of steel to the company’s Vulcraft divisions, the mini mill soon expands production to accommodate outside customers.

With the company now on its way to becoming a highly focused steel producer, the board of directors of Nuclear Corporation of America approves a name change to Nucor.

1972 – On The Big Board

1973 – Credit Where Credit Is Due

Nucor offers a 5-cent cash dividend per share of the company’s common stock, and has paid a quarterly dividend ever since. A year later, the Nucor Foundation is established for teammates’ children. Since 1974, Nucor has contributed over $97 million to scholarships and educational disbursements. And in 1975, Nucor begins the tradition of listing teammate names on the cover of the annual report.

1975 – Deep in the Heart of Texas

Sensing an opportunity in a market experiencing short-term steel shortages, Nucor begins operation of its third mini mill in six years. Located in Jewett, Texas, Nucor Steel Texas is sixty miles from the Vulcraft plant in Grapeland.

1986 – Fasten Up

The company enters the steel fastener market with a new production facility in St. Joe, Indiana.

1988 – Beaming Business

Nucor-Yamato Steel Company forms as a joint venture between Nucor and Yamato Kogyo with the goal of manufacturing wide-flange beams in Blytheville, Arkansas.

By 2015, the Buildings Group has an annual capacity of approximately 465,000 tons.

1989 – A World First

A new era of steelmaking begins when thin-slab technology goes on-line at the new mini mill in Crawfordsville, Indiana. It is the first mini mill in the world to make quality flat-rolled steel using the technology.

1992 – A Second in Arkansas

In 1992, after three years of successfully producing sheet using thin-slab technology, Nucor opens a second sheet mill in Hickman, Arkansas, not far from Nucor-Yamato Steel Company. With two large mills in Mississippi County, northeast Arkansas is one of the top steel-producing regions in America.

1996 – Racing to the Top

A third sheet mill is added to the company’s portfolio when Nucor Steel Berkeley begins operations. The next year Nucor announces plans to build a beam mill on the site. With its expansion, Nucor soon passes Bethlehem Steel to become the No. 2 steelmaker in the U.S.

2002 – No Rolling Required

Castrip® technology goes on-line in Crawfordsville, Indiana. The process casts molten steel directly into sheet steel at or near its final thickness, eliminating the need for large hot and cold rolled reductions. Compared to the casting and rolling process of an integrated steelmaking facility, the Castrip process consumes about 95 percent less energy and emits less than one-tenth the greenhouse gases.

2002 – Gaining Momentum

Nucor’s acquisition strategy moves into high gear. In July, Nucor acquires Trico Steel, which becomes Nucor Steel Decatur, LLC.
