CRGO electrical steel coils can be slit into customer-specified widths for transformer core manufacturing. Conventional and high-permeability grain-oriented electrical steel grades are available, subject to confirmation of the required magnetic properties, thickness, slit width, tolerance and coil dimensions.
CRGO electrical steel coils can be slit into customer-specified widths for transformer core manufacturing. Conventional and high-permeability grain-oriented electrical steel grades are available, subject to confirmation of the required magnetic properties, thickness, slit width, tolerance and coil dimensions.
Slitting requirements are reviewed together with the downstream core-processing method to reduce specification mismatches and support consistent material handling and production.
| Parameter | Available Specification |
| Material | Cold-rolled grain-oriented electrical steel |
| Common Market Terms | CRGO slit coil, CRGO slit strip, grain-oriented electrical steel strip, silicon steel strip |
| Material Type | Conventional / high-permeability GOES |
| Nominal Thickness | 0.23 / 0.27 / 0.30 mm |
| Parent Coil Width | 800–1000 mm |
| Slit Width | According to the confirmed customer specification |
| Width Tolerance and Edge Requirements | Confirmed before production |
| Coil Inner Diameter | 510 mm |
| Parent Coil Weight | Typically 3–5 metric tons per coil |
| Finished Coil Weight | According to slit width and agreed coil configuration |
| Delivery Form | Slit coil / slit strip |
