Peeling
Peeling is the process of removing material from the surface of hot-rolled bars to eliminate the decarburized layer and surface defects. It is preferred especially for larger diameters (15-160mm) and provides a smoother surface than cold drawing.

Dimension Table
| Profile | Size Range (mm) | Tolerance | Standard | Surface (Ra) |
|---|---|---|---|---|
| Round | 15 - 30 | h9 | EN 10278 | ≤ 1.6 µm |
