About Us

In 2018 we became a valuable part of the Steel Dynamics Flat Roll team. Located in Terre Haute, Indiana, SDI Heartland Division produces various types of value-added, flat rolled steel by further processing hot-rolled coils into pickle and oiled, cold rolled and galvanized products.

SDI Heartland Division has the annual capability to pickle and cold-reduce one million tons, with the ability to galvanize 360,000 tons. Our facility is comprised of a continuous pickle line, a two-stand reversing cold mill, batch annealing bases, a temper mill and a galvanizing line. The geographic proximity of the SDI Heartland Division to Steel Dynamics’ other flatroll operations provides opportunities related to logistics and production efficiencies throughout the supply chain and customer network.
