Gränges will invest $110 million to expand its aluminum rolling operation in Huntingdon, Tenn., in an effort to meet growing demand for light-gauge foil, automotive heat-exchanger materials and HVAC applications. The expansion will create 85 permanent full-time jobs. The project includes investment in annealing furnaces, casters, cold-rolling mills and slitters. When completed, the capacity in Huntingdon will increase from about 160,000 metric tons to nearly 200,000 metric tons per year. The expansion is expected to take about two years to complete.
