Nucor Corp. will invest an estimated $176 million to build a hot band galvanizing and pickling line at its sheet mill in Ghent, Ky. The new line will have an annual capacity of 500,000 tons and expand Nucor Steel Gallatin's product capabilities. The project will create 75 new full-time jobs. The 72-inch galvanizing line will be the widest hot-rolled galvanizing line in North America, according to Nucor, and it will create synergies with the company’s other sheet mills. Once the necessary approvals are obtained, it is expected to take two years to construct the galvanizing line and begin operations.
