Cold rolled steel has a smooth surface texture and is commonly used in objects that require the integration of strong steel shapes. The process is done at or around room temperature; the steel is usually covered in oil and then shaped. Hot Rolled Steel Vs. Cold Rolled Steel SciencingThe finished material appears dark gray and has a smooth, reflective surface that is resistant to corrosion, thanks to a stable oxidation film on the surface of the finished steel. Cold-rolled steel is also up to 20 percent stronger than hot-rolled steel, making it ideal for parts that require minimal mechanical fluctuation under pressure.
