Flat Rolled

Carbon steel sheet is SDI’s primary steel product, with our Flat Roll Group having a combined capacity of 7.4 tons per year. 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 36 to 76 inches and in thicknesses ranging from 5/8-inch down to .042-inch. 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 and as thick as .085 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.
