Suitable surface treatments

feature

Ordinary level surface（FA）

Rolling surface
Pickled surface

Allow the surface depth (or height) no more than half the plate thickness tolerance of pitting, concave, scratches and other minor, localized imperfections, but should ensure that the minimum thickness of the steel sheet and strip allowed.

Higher surface（FB）

Pickled surface

Allowed surface does not affect the moldability of local imperfections, such as minor scratches, slight indentation, slight pitting, slight roll printing and color and so on.
