Carbon steel sheet is SDI’s primary steel product. We produce hot-rolled coils (HRC) in a variety of gauges and grades, and then finish and coat a high proportion of this flat-rolled steel sheet.
Hot-rolled steel sheet
We produce carbon steel sheet in widths from 40 to 61 inches and in thicknesses ranging from 3/8-inch down to very thin gauge. We specialize in thin-gauge, high-strength alloy steels, hot-rolling steel sheet as thin as 0.045 inches. Our capabilities range from formable low-carbon grades to ultra-high-strength steels.
Cold-rolled steel sheet
After hot-rolled sheet is pickled, leveled, and edge-trimmed, our cold-rolling mill is capable of reducing the steel’s thickness to as thin as 0.013 inches.
Coated flat-rolled steel sheet
We galvanize hot-rolled and cold-rolled steel sheet, offering galvanneal and Galvalume, as well as acrylic overcoat options. We also pre-paint coils. More »
