SDI is the third largest steel producer and the second largest metals recycler in the United States. Based in Fort Wayne, Indiana, SDI employs over 8,000 people at its steel mills, metals-recycling yards, and steel finishing, coating, and fabrication facilities.
Due to our unique capabilities, we are the only mill in the Western Hemisphere that produces rail in lengths of 320 feet, which can be cut into shippable lengths and transported by truck or railcar, or welded together right here at our on-site welding facility to create Continuous Welded Rail (CWR) in lengths up to 1,650 feet and shipped via CWR unit trains.
With the addition of a state-of-the-art SDI Research and Development Center, we are actively pursuing product development initiatives to bring the next generation of quality rail products to market. We are 100% American owned and operated, and our rail products are made from locally sourced American recycled steel.
