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.
