Cold rolled steel, also called CRS, is a process used to finish steel. Hot rolled steel is steel that is still warm enough to be malleable and run through pressure rollers. After cleaning, when the steel has cooled and is no longer elastic, the steel is then put through power rollers and cold rolled between two large rollers. This produces a product that has a fine, smooth finish.
The cold rolled steel process is formed into its final shape when the metal’s temperature is below 1700 F, typically at room temperature. At this lower temperature, cold rolled steel does not shrink allowing for better accuracy when measuring it.
Cold rolled steel is usually chemically treated to lessen corrosion. It has a uniform attractive surface and can be easily painted.
