HarbisonWalker International (HWI) is investing to increase capacity by 25% at key steel refractory facilities. Most of the investment will be at its facility in White Cloud, Mich., which manufactures refractory products primarily for steelmakers. According to the company, approximately half of its capital investment dollars will have a direct positive impact on its steel industry customers. The investment will include expansion to accommodate new warehouse and shipping space, which is being constructed with American-made steel. Additional manufacturing space will house new technologies that improve production efficiency and worker safety.
