>Cold Rolled: How It Is Made | Steel Supplier | Metalwest
Cold rolled is the next step along the line of flat-rolled steel products. The process starts with hot rolled P&O. Hot rolled is processed to a final thickness that is heavier than most sheet products. A cold-reducing process is used, which results in a thinner thickness. The cold reduction starts with tension to the sheet.
