| | REF | FINISH | NOTES | | 0 | HOT ROLLED AND SOFTENED BUT NOT DESCALED | Suitable only for certain heat-resisting applications, as the presence of oxide scale impairs resistance to corrosion. Surface inspection is not practicable. | | 1 | HOT ROLLED,SOFTENED AND DESCALED | Generally used when smoothness and uniformity of finish are not important. It's is permissible for grinding marks to be present. | | 2D | COLD ROLLED,
SOFTENED AND DESCALED | A uniform matt finish. | | 2B | COLD ROLLED, SOFTENED, DESCALED AND LIGHTLY ROLLED ON POLISHED ROLLS | A smooth finish for general applications, brighter than finish no.2D | | 2A | BRIGHT ANNEALED
(BA) | A cold rolled reflective finish retained through annealing. |
| | | REF | FINISH | NOTES | | 3A | GROUND | A uniform coarse ground finish generally obtained by treatment with abrasives of 80 to 100 grit size. | | 3B | DULL BUFFED | A uniform straight grained finish, generally achieved in one pass, applied to 2B or 2A mill finish: produced by polishing with 180 to 220 grit size abrasive belts. | | 4 | POLISHED WITH FINE GRIT | The final polishing, generally produced by treatment with successively finer abrasives of 180 to 240 grit size, gives an undirectional texture, not highly reflective | | 7 | BRIGHT BUFFED | A bright finish, generally applied to 2B or 2A mill finish, by treatment with fibre suitable polishing compound. | | 8 | BRIGHT POLISHED | A bright reflective finish with a high degree of image clarity. Produced by polishing with successively finer grits followed by buffing with a very fine polishing compound. |
