FC: advanced surface finishing: The better side of the SC1 Cold-rolled steel plate must be further limited to the defect, no obvious visible defects, the other side should meet the FB surface requirements.
FD: extra-advanced surface finishing: The better side of the SC1 Cold-rolled steel plate must be further limited to the defects, that is, does not affect the appearance of paint or after plating quality, the other side should meet the FB surface requirements.
