Carbon steel sheet is SDI’s primary steel product, with our Flat Roll Group having a combined production capacity of 11 million tons annually. We produce hot roll coils (HRC) in a variety of gauges and grades, and have capabilities to finish and coat our steel sheets to meet our customers’ needs.
Hot-roll 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-roll 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 steel sheet
We galvanize hot-roll and cold-roll steel sheet, offering galvanneal, Aluminized Type 1 and Galvalume®, as well as acrylic overcoat options.
Painted steel sheet
We also pre-paint coils with thickness ranging from .012 inches to .071 inches and width ranging from 36 inches to 61.5 inches.
