Nucor Corp. says it will invest approximately $110 million to install a plate heat-treating facility at its plate mill in Hertford County, N.C. With an estimated annual capacity of 120,000 tons, the new heat-treat line will be capable of producing heat-treated plate from 3/16 through 2 inches thick. Installation of the facility will begin after resolution of regulatory approvals and finalization of equipment contracts.

Nucor’s plate mill in Hertford County started operations in 2000 and has an annual capacity of approximately 1.6 million tons. Combined with its plate mill in Tuscaloosa, Ala., Nucor’s current plate production capacity is around 2.8 million tons per year.
