Cold Rolled Steel Coil

Steel sheets that has been pickled and run through a cold- reduction mill.

Cold rolled steel is the outcome of steel that has been flattened between rollers below its recrystallization temperature, which allows the alloy to be stronger by increasing its strain hardness. Cold Rolled steel sheet is considerably thinner and stronger than hot rolled coils.
