• Cold Rolled Steel Coils / Sheets (CR)

    CR COILS and Sheets

    C. R. Sheets/ Coils. CR sheets or cold rolled sheets are hot rolled products which provides a superior surface finish, with improved physical properties of the steel, such as high formability, high strength, excellent dent resistance, good magnetic properties, tensile strength, and workability and welding properties.
    JS Metals supplies CR Sheets and Coils thru out UAE and Middle East . We supply Hot Rolled Coil and Cold Rolled Coil with different specification . Our supply chain covers Dubai, Abudhabi, Fujairah, Ras Al khaimah, Sharjah, Alain and other emirates and parts of United Arab Emirates (UAE).

    Applications of CR Coils

    CR coils/sheets are used for precision tubes making, containers, bicycles, furniture, household appliances, electrical panels, galvanizing, colour coating, thinning, general engineering and construction. Automobile industry uses CR Sheets to produce car body panels.

    Differences between Hot Rolled Coil and Cold Rolled Coil

    1 , Differences in rolling process:

    Hot rolling is a metallurgical process that mainly to produce steel sheet or Steel Plate, after being passed between a set of work rolls, the billets are simply deformed or cut into steel plate, and the rolling temperatures would be over 1,000 degrees Fahrenheit. Cold rolling is another metal working process at temperatures that are close to normal room temperature, deform metal by passing it through rollers. Cold rolling often used to decrease the thickness of steel plate or steel sheet, and increase the metals yield strength and hardness.

    2 , Advantage and disadvantage: Hot Rolled Steel vs. Cold Rolled Steel

    The cold rolled steel is more precise dimensionally than a hot rolled product that created by hot rolling process, The cold rolled steel has already gone through the cooling process, which help it closer to the finished dimension. However, the shapes of cold rolled steel is limited because of these properties, round, square, flat and variations of those types of shapes. If with small transverse dimension and uniform cross section, other shapes can also be cold rolled. During the cooling process, Hot rolled steel re-configures itself, which giving the finished product looser tolerances than the original material. Compared with cold rolled steel products, Hot rolled steel is more malleable, allowing it to be forced into a variety of different shapes.

    Application of Hot Rolled Steel and Cold Rolled Steel

    Hot rolled steel always used to create larger size products, as those larger products need to be in more distinct shapes. Hot Rolled Coil is produced as a feedstock for Cold Rolled Coil and coated coil, but also for immediate use in a variety of industrial applications including Steel Tubes used in transport, shipbuilding, construction, gas containers, pressure vessels and energy pipelines.

    And Smaller products need to be more durable and tolerant, always created by the Cold Rolled Steel. Cold Rolled Steel is a ‘flat’ steel product. The material is manufactured from Hot Rolled Steel, with further thickness reduction performed on a strip mill without the use of heat. The application of cold rolled steel including: Automotive components, Bathtubs, Construction and building components, Domestic appliances, Electrical goods, Furniture, etc

    The cold rolled coils are manufactured from the hot rolled coils. The hot rolled coils are cleaned chemically and processed further in cold reduction mills, where the material is cooled (at room temperature) followed by annealing and/or tempers rolling. This process will produce steel with closer dimensional tolerances and a wider range of surface finishes. Cold rolling increases strength, enhances the surface finish and offers uniform thickness. To prevent the cold rolled coils from rust, they are usually coated with thin layer of oil. Further coating of Zinc-Aluminium alloy or galvanization on the metal can be processed. Js etals offer cold rolled coils in a range of international standard grades.

    Js Metals is one of the premier names in the industry that offers a qualitative range of Cold Rolled Steel Coils/Sheets. These are manufactured and supplied as per the specific market demands. We offer these in varied specifications as per the requirements of our esteemed clients. These are widely used for manufacturing superior quality carbon steel plates with consistent and controlled properties.
