What is the difference between cold formed and hot rolled ...
Hot rolled steel is formed while at a high red or orange heat (1500°f1800°f). This allows it to be formed faster and/or into more drastic shapes. Down side is that the hot steel cools and shrinks, so size tolerance has to be somewhat loose. Cold rolled steel is final formed when at a black heat (roughly 400°f .
