St44-3G carbon structural steel surface quality:
Relatively high-grade finishing surface FB(03)-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(04)-One side of relatively good quality is free from any remarkable defect visible and the other side must reach FB requirements at least.
