CR Sheet (Cold Rolled Sheet)

Cold Rolled Sheets (CR Sheets) are manufactured by rolling hot rolled steel coils at room temperature below their recrystallization point, which enhances their surface finish, strength, and dimensional accuracy. CR Sheets offer excellent flatness and a smooth surface, making them ideal for applications that require tight tolerances and superior aesthetics. Their consistent thickness and precise mechanical properties make them highly suitable for precision engineering and fabrication work.

At Kaustubh Enterprises, we provide premium-quality CR Sheets that meet industrial standards for durability, strength, and performance. These sheets are widely used across sectors such as automotive, electrical, appliance manufacturing, furniture, and construction. Our CR Sheets are available in various grades, widths, and thicknesses to suit diverse industrial requirements, ensuring efficiency, reliability, and a professional finish in every application.
