Peeled bars are high-precision steel products made by machining the surface of hot rolled steel bars at room temperature (removing a layer of chip). This method improves surface quality, tightens dimensional tolerances and removes minor surface defects and hairline cracks.

During peeling, possible hairline cracks on the surface are eliminated while high precision is achieved in diameter and cross-section.

These products are generally subjected to internal and external defect inspection; after surface hairline defects have been removed by peeling, they are used as zero-defect material for safety-critical parts in the automotive industry.
