  each roller can also be adjustable slightly.
>> Shallow “R” groove of the rollers ensure finish straightening accuracy.
>> The surface of rollers are covered with Nickel & Phosphorus and polished to improve hardness and wear, the polished
  surface can effectively decrease the adhesion of dust and Al flash.
