Cold Rolled Coil

Cold rolled steel is essentially hot rolled steel that has had further processing. The steel is processed further in cold reduction mills, where the material is cooled (at room temperature) followed by annealing and/or tempers rolling .

Unique Properties of Cold Rolled Steel

While Hot Rolled Steel is used in applications that do not require precise shapes and tolerances (like I-beams and railroad tracks), Cold Rolled Steel is known for its ability to hold tight tolerances and retain few surface imperfection

It’s important to note that the main difference between hot rolled and cold rolled steel is one of process. “Hot rolling” refers to processing done with heat. “Cold rolling” refers to processes done at or near room temperature. … It may seem obvious, but some types of steel are better suited for certain applications

Hot rolled steel typically requires much less processing than cold rolled steel, which makes it a lot less expensive. Hot rolled steel is also allowed to cool at room temperature, so it’s essentially normalized, meaning it’s free from internal stresses that can arise during quenching or work-hardening processes
