Cold Rolled Coils

Cold rolled steel is essentially hot rolled steel that has had further processing. The steel is processed further in cold reduction mills, where the material is cooled followed by annealing and/or tempers rolling. This process will produce steel with closer dimensional tolerances and a wider range of surface finishes. All cold products provide a superior surface finish, and are superior in tolerance, concentricity, and straightness when compared to hot rolled. Slabs are semi-finished steel and are the end result of rolling ingots on a rolling mill or by processing them through a continuous casting process. Slabs will have rectangular cross sections and are used as the “starter” metals in the making of flat products such as steel plates or hot rolled coils. Slabs are always flat and rectangular and will typically range from 160 mm thicknesses and more.
