Aleris will invest $350 million to upgrade its aluminum rolling mill in Lewisport, Ky. The investment will include the addition of heat-treatment and finishing capabilities, most notably two continuous annealing lines and an automotive innovation center. The company expects construction to begin this fall, with the goal of shipping automotive body sheet material to customers by early 2017. When fully operational, the facility will allow for the production of 480 million pounds of aluminum auto body sheet annually.
