Peeled Bright Steel Bar specifically is a machining process used to take a raw forged blank to a polished bar. During the bar peeling process, the forged bars are machined to remove surface cracks, cooled layers of "skin," and oxide.
It is during the peeling process that the requested dimensions and specifications are achieved on the machined parts, such as: accurate dimensions, surface quality factors, and roundness. Peeled bars are obtained by removing the "skin" of the bar with a special tool; after peeling we carry out straightening and controls on the bars to avoid any defects going to the client. All peeling lines are equipped with eddy current controls.

During the peeling process the round steel is subjected to chip removal which makes the surface bright and smooth. Moreover, the chip removal eliminates potential surface defects of the rolled material. As a result, the product is technically free from surface defects. After peeling the bars are straightened, thereby improving the straightness and the roughness of the bars.
