Finish Definition:
No.2D: Cold-rolled, annealed and pickled without skinpass. the dull
products can be used as automobile parts,building materials and
pipes
No.2B: The surface brightness and flatness of No.2B is better than
No.2D. Then through a special surface treatment to improve its
mechanical properties. No.2B could nearly satisfy comprehensive
uses.
No.3: Polished with abrasive belt of grit #100-#120, have better
brightness with discontinuous coarse stria, used as inner and
external ornaments for building.electrical applicances and kitchen
utensils etc.
No.4: Polished with abrasive belt of grit #150-#180, have better
brightness with discontinuous coarse stria,but thinner than No.3,
are used as bathtub building's inner and external ornaments
electrical appliances,kitchen utensiles and food processing
equipment etc .
HL: Polished with abrasive belt of grit#150-#320 on the No.4 finish
and has continuous streaks, mainly used as building's
ornaments,elevators,door of building,frontal plate etc.
BA: Cold rolled,brigth annealed and skin-passed, the product have
excellent brightness and good reflexivity like mirror,used for
electrical applicances,mirrowr,kitchen apparatus,ornament materials
etc.
