The thickness of steel sheets is usually reduced by passing the cold coil through rolls in a cold mill. These work rolls have a distinct surface texture, often generated by electrical discharge texturing (EDT). When the sheets pass through these work rolls, the texture of the work rolls will be imparted on the surface of the sheets. This surface characteristic may influence the sheet's paint ...
