Steel Dynamics in 2010 entered the market for standard-strength railway rail after certification of our rail by America’s Class I railroads. Uniquely in North America, SDI produces rail in lengths of 320 feet, which can be shipped in this long length, cut to shorter lengths (commonly in lengths of 39, 40 or 80 feet), or welded together to create long rail strings.
AREMA standard rail sections in 115RE, 136RE, and 141RE weights. Sections up to 320-feet in length.
Steel Dynamics produces continuously welded rail (CWR) strings up to 1650 feet long. Our state-of-the-art rail-welding facility located near our steel mill at Columbia City, Indiana, is designed to handle our mill’s long-length rails, minimizing the number of welds in each rail string.
