Commercial Metals to Build New Arizona Micromill

Commercial Metals Co. (Irving, Texas) plans to construct a new $300 million electric-arc furnace in Mesa, Ariz., adjacent to its existing mill there, it announced in August.

The new “Triple M” mill will be the first micromill capable of “continuous-continuous” production of merchant bar quality steel, CMC says.

The mill will have an estimated nominal annual capacity of 500,000 tons, including 150,000 tons of merchant bar quality steel, the company says. The electric-arc furnace technology it is installing is capable of using solar or wind power sources; CMC says it plans to construct a solar array to provide some power to the facility.

In related news, CMC plans to shut down its Rancho Cucamonga, Calif., EAF and sell that property, noting that the new mill will operate at a lower cost and more efficiently. The Rancho Cucamonga melt shop has been idle since October 2019. Visit
