The meltshop will be equipped to produce 600,000 tons annually, Nucor said, and will create approximately 140 new jobs. 

"This investment in a new meltshop at our Arizona bar mill is part of our strategy to grow our core steelmaking business and will help us maintain our market leadership position in steel bar production," said Nucor president and chief executive Leon Topalian. "Adding new meltshop capacity will help meet the growing demand for steel bar products in the Western region, which is one of the fastest-growing areas in the U.S.," he said. 

Nucor announced nearly a year ago that it would add a meltshop to a bar mill in the western U.S. The Kingman plant has no melt capabilities and re-rolls billet into coiled wire rod and rebar.
