Cold Rolled Steel
Cold Rolled Steel products come in a variety of inventory. It is essentially hot rolled steel that has been processed further in cold reduction mills, where the material is cooled (at room temperature) followed by annealing and/or temper rolling.
Cold rolling increases the strength and hardness while decreasing ductility of steel by rolling it at ambient temperature (or below its recrystallization temperature). In addition to improvement of mechanical properties, cold rolling results in more control over the shape and dimensions of the finished product.
Benifits
Dimensional Accuracy
More precise dimensionally than a hot rolled product created by the hot rolling process. The Cold Rolled Steel has already gone through the cooling process, which helps it remain closer to the finished dimension requirements.Improved Strength & Hardness
The cold rolling of hot rolled steel increases the strength and hardness while decreasing the ductility of the steel. When a metal is cold rolled, it is plastically deformed as it is forced between rolls. This deformation causes dislocations of atoms within the metal causing them to over-lap each other and increasing density. Increased density means greater metal strength and hardness.Superior Surface Finish
The finish on cold rolled products provides a uniform dull surface that is smoother than hot rolled and suitable for painting or lacquering.Meets ASTM A568 requirements
ASTM Designation A568 outlines the general requirements for Cold Rolled Steel. Included in this specification are steel chemistry requirements and typical mechanical properties of various metallurgical grades.

Options
Annealing
Steel can be partially or fully restored to its original properties through an annealing process. Annealing consists of heating the steel to above the recrystallization temperature, soaking at that temperature and then cooling the steel. Heating of the steel during annealing facilitates the movement of iron atoms, resulting in the disappearance of dislocations as well as the formation and growth of new grains of various sizes. The three stages of annealing are recovery, recrystallization, and grain growth.
End-Use Applications
Cold Rolled Steel coil is produced as a feedstock for metallic-coated coils such as galvanized or galvanealed steel. Cold rolled with an improved surface finish which makes it ideal for use in furniture, appliances and other consumer goods. Cold Rolled products can also be powder coated for post-paint applications. Other applications of Cold Rolled Steel include automotive, railway components, construction and building components, storage racks, grain bins, partitions, HVAC intakes/exhausts as well as electrical goods. Cold Rolled Steel is also frequently used in construction of bridges, highway products, transmission towers and poles, and various types of equipment.
