Features |
Relatively high-grade finishing surface |
FB(O3) |
It is allowed for the existence of a few surface defects which will not affect forming and coating & plating adhesiveness such as minor scratch, impression, pit, roll mark and oxidation tint.
|
High-grade finishing surface |
FC(O4) |
One side of relatively good quality is free from any remarkable defect visible and the other side must reach FB requirements at least. |
Packaging of Cold Rolled Steel Coil:
Products of Shanghai Metal Corporation are packed and labeled according to the regulations and customer's requests. Great care is taken to avoid any damage which might be caused during storage or transportation. In addition, clear labels are tagged on the outside of the packages for easy identification of the product I. D. and quality information.
