Rolled Sheet DC01 CR Cold Rolled Coil

Cold-rolled sheet in coil form is produced by removing rust from hot-rolled sheet by "pickling" it in a weak acid solution, then washing, brushing, drying, oiling and unrolling the sheet and finally performing cold-rolling by passing the sheet through a reducing mill under pressure and winding it into a roll. Cold-rolled steel is a more highly finished product and has a smoother surface, greater dimensional accuracy (thickness, width, length) and greater strength. Much cold-rolled steel is processed in the automotive industry, but some is also used in the manufacture of household goods.
