Cold-rolled sheet steel is produced from hot-rolled sheet with additional processing steps such as pickling, cold reduction, annealing and temper rolling. Cold rolled steel is used for automotive parts, electrical motors, major appliances, industrial packaging, strapping, office furniture and tubular goods.

Full Hard

  • Cold Roll Full Hard is manufactured from hot rolled coils by pickling to remove the surface oxide, and cold reducing the steel through the Cold Mill to the desired thickness in one continuous operation. Full hard product has extremely low ductility and usually requires further processing.

Conventional

  • Conventional cold roll is produced by further processing the full hard coils to develop the desired end use characteristics such as formability, surface texture, flatness, etc. The full hard coils are first batch annealed and then temper rolled for formability and surface texture, and in some cases, tension levelling for flatness.
