Cold Rolled (CR) Sheets are precision-manufactured steel products created by further processing hot-rolled steel at room temperature. After the initial hot-rolling process, the steel is allowed to cool and then passed through cold-reduction mills. This "cold working" logic compresses the steel, resulting in a refined grain structure that provides higher tensile strength and hardness compared to standard hot-rolled sheets. CR sheets are characterized by their exceptional surface finish, which is smooth, clean, and often lightly oiled to prevent atmospheric oxidation. They offer extremely tight dimensional tolerances and a uniform thickness across the entire sheet, making them the industry standard for high-precision manufacturing. In Nepal's industrial sector, these sheets are the primary choice for applications where aesthetics, precision bending, and a superior base for painting or powder coating are required.
