The main classification of cold rolled steel coil
Cold rolled steel coils generally include medium-thick and wide steel strips, hot-rolled thin-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 cold rolled steel coil output.
Medium-thickness and wide steel strips refer to steel strips with a thickness ≥ 3 mm and less than 20 mm, and a width ≥ 600 mm, which are produced and delivered in coils with continuous wide-band steel hot rolling mills or steckel rolling mills.
Hot-rolled thin-wide steel strip refers to a steel strip with a thickness of <3 mm and a width of ≥600 mm, produced by continuous wide-band steel hot rolling mill, steckel rolling mill, or thin slab continuous rolling equipment, and delivered in coil form.
Cold rolled steel coil refers to a single steel plate with a thickness of <3 mm. Cold rolled steel coils are usually produced by continuous wide-band steel rolling mills, thin slab continuous casting and rolling equipment, and steel strips for plate delivery.
