Yogic offers the Cold Rolled sheet in a variety of sizes, grades and surface finishes to meet specific end-use requirements. Cold Rolled Sheet is manufactured from hot rolled coils by pickling to remove the surface oxide produced during the hot rolling stage, and cold reducing through a Cold Mill to the desired thickness.

Cold reducing steel produces an extremely low ductility product. It's usually processed further to develop desired end use characteristics such as formability, surface texture, flatness, etc. These further reprocessing steps include annealing and temper rolling for formability and surface texture, and in some cases, tension levelling for flatness

1.Sophisticated Surface and Dimensional Accuracy

A cold-rolling reduction rate of 40% or higher severely compromises the cohesiveness of a metal structure because it aligns the metal grains in the direction of rolling. However, recrystallization through the annealing processhardens the steel but eliminates the hard, brittle qualities resulting from the cold reduction process. Cold- rolled steel sheet that has undergone the annealing process has increased workability compared to cold-rolled sheet produced by the conventional method. Sheet and coil can be produced at various grades of workability by altering the annealing and cold-rolling conditions

2.Excellent Workability

Using the cold rolling process, cold-rolled steel plate undergoes annealing and temper-rolling to achieve a consistent, smooth surface with uniform thickness and flatness. Additionally, these treatments provide cold-rolled steel sheet and coil with superior mechanical properties. As a result, cold rolled sheet and coil have a high level of workability and are suitable for metallic coating, painting and other similar treatments.

3.Various Applications Cold-rolled steel sheet and coil is essential to automotive and electrical appliance production as well as a wide range of other products requiring tons of highly workable steel of a consistent quality. They also serve as the base metal for tinplates, galvanized sheet and other coated steel products. Since they are used in such varied products, cold-rolled steel sheet must be available with a variety of properties. Increased demand for sophisticated and specialized products has prompted the production of specialized cold-rolled steel with properties like deep drawability and high tensile strength.
