Mill scale is a uniform layer of various iron oxides and other impurities that covers the surfaces of hotrolled steel. When machinery rolls the hot steel to form it, the air's oxygen reacts with the hot iron and creates these oxides. Mill scale has a black or blackblueish color and spreads evenly over the entire surface.
Internal diameter of a wire rod coil normally varies in the range of 810 mm to 910 mm depending on the mill equipment. The external diameter of the wire rod coil depends on its weight and is normally in the range of 1,100 mm to 1,300 mm. The coil weight can vary from mill to mill in the range of 600 kilograms to tons.

"Seams are longitudinal crevices that are tight or even closed at the surface, but are not welded shut. They are close to radial in orientation and can originate in steelmaking, primary rolling or on the bar or rod mill."
