Gerdau Macsteel’s Board of Directors has approved a $9.4 million expansion at its Huntington, Ind., heat-treat operation. The expansion will add a fifth quench-and-temper line with induction heating – similar to the facility’s existing four lines. The project is scheduled for completion in the fall of 2009. It will add 18,000 tons of additional bar and tube capacity, increase the size range of Gerdau Macsteel’s products and expand its value-added services.

The expansion also includes a new 30,000-square-foot building and state-of-the-art bar straightening equipment. Gerdau Macsteel, headquartered in Jackson, Mich., is one of the largest producers of SBQ-engineered steel bars in North America.
