Cold rolled steel has a much smoother appearance and is stronger than hot rolled steel. It is the next step along the line of flat-rolled steel products. The process of creating cold rolled steel begins with hot rolled P&O. The hot rolled P&O is sent through a cold reduction process which creates a thinner thickness and a harder surface.
