Hot-rolled coils generally include medium-thick and wide steel strips, hot-rolled thin and wide steel strips and hot-rolled sheets. Medium-thick and wide steel strip is the most representative variety, and its output accounts for about two-thirds of the total output of hot-rolled coils. The subject matter of the hot-rolled coil futures contract to be listed on the Shanghai Futures Exchange is medium-thick and wide steel strip.

Medium-thick and wide steel strips refer to steel strips with a thickness of ≥3mm and < 20mm and a width of ≥600mm, produced by continuous wide-band steel hot rolling mills or Steckel rolling mills and delivered in rolls.

Hot-rolled thin wide steel strips refer to steel strips with a thickness of <3mm and a width of ≥600mm, produced by continuous wide-band steel hot rolling mills or Steckel rolling mills or thin slab continuous rolling equipment and delivered in rolls.

Hot rolled sheet refers to a single steel plate with a thickness of less than 3 mm. Hot-rolled thin plates are usually produced by continuous wide-band steel rolling mills, thin slab continuous casting and rolling and other equipment and are delivered in flat form.
