SDI Chooses Columbus, Miss., for Aluminum Mill

By on
Steel Dynamics will locate its first aluminum flat-rolled mill in Columbus, Miss., near its existing flat-rolled steel mill. Columbus was chosen given its location within the targeted Southeast market.

“We are extremely excited to announce Columbus, Miss., as the location for our new next-generation recycled aluminum flat rolled mill,” said Mark D. Millett, chairman, president, and CEO. “We are eager to expand our presence in Columbus, and we deeply value the warm welcome and support that we have received from the community, officials, Governor Tate Reeves, and the State of Mississippi.  

SDI officials said the Columbus, Mississippi location brings numerous advantages, including:

• Sufficient acreage to allow strategic customers to co-locate on site, providing a baseload volume opportunity for our aluminum mill, while providing customers with shorter lead times, logistics savings and meaningful working capital savings.

•  Synergies related to the close proximity of its Columbus Flat Roll Steel Division.

•  A talented workforce that is driven by our unique entrepreneurial, performance-based culture.

•  Excellent logistics provided by on-site access to a class I railroad, proximity to the major U.S. highway systems, and access to the Tennessee-Tombigbee Waterway;

•  Existing, mature, and dependable natural gas, water sources, and access to ample renewable power.

The planned $1.9 billion aluminum flat-rolled mill is designed to have an annual production capacity of 650,000 metric tons of finished products, serving the sustainable beverage packaging, automotive and common alloy industrial sectors. The product offering will be supported by various value-added finishing lines, including continuous annealing solutions heat treating lines, continuous coating and various slitting and packaging operations. The rolling mill is currently expected to begin operations in mid-2025.

The company’s focus on decarbonization will also be applied to this aluminum operation, including plans to use a significant amount of pre- and post-consumer aluminum scrap in its production process, supported by the company’s metals recycling platform, which is the largest nonferrous metals recycler in North America.

“We are eager to move this significant growth investment forward,” said Millett. “We have intentionally grown with our customers’ needs, providing efficient sustainable supply-chain solutions for the highest quality products. Thus far, this has primarily been achieved within the carbon steel industry – however, a significant number of our flat-rolled carbon steel customers are also consumers and processors of aluminum flat-rolled products. This investment broadens our ability to serve our existing and new customers by adding high-quality, low-carbon footprint flat rolled aluminum to our product portfolio."
