SDI to Invest in Four New Coating Lines
Written by Sandy Williams
Steel Dynamics Inc. announced today a major investment to establish four new coating lines—two in the South and two in the Midwest.
The $225 million investment in the southern location will support the new Sinton, Texas, steel mill, which is on track for first production in late summer 2021. A 300,000-ton flat-roll galvanizing line with Galvalume coating capability is planned, as well as a 240,000-ton paint line. Galvalume products are used primarily in the metal building industry, which has sourced as much as 45% of its needs through imports, said SDI.
