Producer
Nucor Corporation
American steel company (NYSE: NUE, HQ Charlotte NC; ~$34B revenue at peak 2022); largest US steel producer by volume using electric arc furnace (EAF) mini-mill technology primarily with scrap steel feedstock. Nucor's Steel Technologies distribution subsidiary and Nucor's own galvanizing operations supply galvanized steel to center pivot irrigation manufacturers (Valmont, Lindsay) through its tubular products and steel processing divisions. Nucor pioneered the EAF mini-mill model in the 1960s-70s under CEO Ken Iverson, disrupting integrated blast furnace steel producers by using cheap scrap steel instead of iron ore — a management case study still taught in business schools. The same Nucor EAF innovation that disrupted US Steel and Bethlehem Steel in the 1970s now supplies the galvanized steel that makes center pivot irrigation systems that grow the corn in the Midwest and the wheat in the Sahel.

Did you know2024
Nucor is understood by most observers as a steelmaker. What fewer know is that Nucor, through its David J. Joseph Company (DJJ) subsidiary, is also one of the largest scrap metal brokers and recyclers in North America. DJJ collects ferrous scrap from demolished buildings, junked cars, and industrial waste streams across the US, processes it, and sells it as EAF feedstock — including to Nucor's own steel mills. Nucor both buys scrap from the economy's discards AND sells new steel to the economy's builders. The steel rebar in a demolished 1970s office building in Cincinnati might exit as scrap through a DJJ collection site, travel to a Nucor EAF in Darlington SC, and re-enter the economy as rebar in a new apartment building in Charlotte. Nucor is simultaneously a scrap recycler and the company that makes steel from that scrap — a circular loop that most steel consumers and construction industry participants have no visibility into.

Nucor Corporation began in 1940 as the Nuclear Corporation of America — a manufacturer of car rooftop carriers, not steel. Under CEO F. Kenneth Iverson in the 1960s, Nucor bet on a radical model: electric arc furnace (EAF) mini-mills using scrap metal instead of iron ore, placed in non-union Southern and Midwestern states rather than the unionized Great Lakes rust belt. This was considered a fool's errand — US Steel and Bethlehem Steel had billion-dollar blast furnaces and seemed unassailable. By the 1980s, Nucor's EAF model had cost-undercut every major integrated steelmaker; by the 2000s, Nucor was America's largest steel producer. The company that started selling car-top carriers in Charlotte, NC became the instrument of the rust belt's deindustrialization — by making cheaper steel.
