The rolling process is done at either a hot temperature or near room temperature. Hot rolling is done at high temperatures (over 1700\u02daF), resulting in steel which is easier to shape, but has a rough, scaly surface. Cold rolling occurs after the steel has already been hot rolled. The steel is then rolled again at room temperature, forming steel which has higher precision, higher strength, and a smooth, more refined finish.<\/p>\n\n\n\n

The main difference between hot rolled and cold rolled steel is in how they are processed. The difference in processing directly affects their shape and properties<\/p>\n\n\n\n

Hot rolled steel is cheaper because the process involves fewer steps and less labor. Hot rolling is produced at high temperatures, where steel is easier to shape. Cold rolled steel is more expensive since it requires additional processing in cold reduction mills.<\/p>\n\n\n\n
