The SDI Flat Roll Group Columbus Division is one of the newest and most advanced facilities of its kind in the world. Completed in 2007 at a cost of $980 million, the Columbus facility underwent a $555 million expansion in 2011 that doubled its size and increased production capacity to 3.4 million tons annually. Located in Mississippi’s “Golden Triangle,” Columbus has unparalleled access to rail, truck, and water routes that enable the division to deliver products faster and more efficiently throughout the growing manufacturing region in the southern United States and Mexico.
