What is a Flat Rolled Steel Coil?

Hot Rolled

This type of coil steel involves rolling steel above its recrystallization temperature, usually about 1700° Fahrenheit. The oxide film is stripped off by either mechanical or chemical method or a combination of both.

Cold Rolled

This type of steel is for either exposed or unexposed applications, which involve bending, forming, welding, or moderate drawing.

A cold rolled metal coil is manufactured by removing rust from a hot rolled coil, soaking it in acid, then washing and drying the sheet. The sheet then passes through a reducing mill under pressure.

Unlike hot rolled steel coil, it is a more finished product with a smoother surface. It also has greater strength and durability.
