Q: What are the surface quality grades of DC06 coil?
A: FB (higher grade), FC (high grade), and FD (ultra-high grade), corresponding to O3, O4, and O5, respectively. FD grade is suitable for applications with high appearance requirements.
Q: What are the surface texture codes for DC06 coil?
A: D (matte finish) and B (gloss finish), selectable according to subsequent process requirements.
Q: What are the thickness tolerances for DC06 coil?
A: High-precision control; thickness difference within the same coil is typically ≤0.01-0.03mm, with a standard tolerance of ±0.1mm. Customization is available for special requirements.
Q: Is delivery of DC06 coil with defects permissible?
A: Yes, but the length of the defective portion must not exceed 6% of the total coil length and must be free of fatal defects such as scabs, cracks, or delamination.
Q: What are the sheet shape requirements for DC06 coil?
A: High flatness precision, with no obvious waviness or warping, ensuring smooth feeding and forming accuracy during stamping.
