About COLD ROLLED

Cold-rolled steel is produced by passing hot rolled steel through rollers below its recrystallization temperature. This process is done to enhance its mechanical and dimensional properties. The metal is compressed and squeezed, resulting in increased yield strength and hardness. Cold rolling of metal strips is a specialized segment in the metalworking industry. Cold-rolled steel has several advantages, such as:

Higher precision

Cold rolled steel can exhibit strength up to 20% greater than that of hot rolled steel, which makes it more suitable for
