There are some small creases present across some portions of the width of the coil, although seldom throughout the entire coil. These creases are similar to the wrinkles left on a piece of cardboard after it has been rolled into a coil.
The breaks occur mainly on soft or very soft steel qualities where the coil doesn’t unfold into a smooth sheet, just as it would happen to the cardboard. They are usually small and approximately 1 meter between each other. The defect is difficult to notice it from the outside of a coil but becomes apparent when the coil is cut into sheets.
The defect is not serious if the coil is to be slit or cut to small sheets/pieces, but for larger sheets the defect is more obvious. The visual flaw is even more noticeable if these sheets are to be painted afterwards.
BEST USE: Slitting
