Steel Dynamics Inc. says the electric arc-furnace unit will be in Sinton, about 25 miles northwest of Corpus Christi.
A company statement Monday said the site is strategically located for the southwestern U.S. and Mexico markets. Steel Dynamics President and CEO Mark Millett says the company has been developing a flat roll steel business strategy for those areas for several years.
"We anticipate the project will create approximately 600 well-paying positions," said Millett.
Company officials say the mill will be able to produce up to 52.5-ton coils for the energy, automotive, construction and appliance industries. The site has transport access to railroads, highways and the Port of Corpus Christi.
Construction should begin next year.
