Finishing procedure and Degree of finish |
| No.1 |
Hot-rolled, annealed and descaled. Generally used in industrial applications, where heat or corrosion resistance is required but surface smoothness is not particularly important. |
| No.2D |
Dull, smooth finish produced by cold rolling, annealing and pickling. Steel is soft andhas a silver white surface, suited for deep drawing as well as general use. |
| No.2B |
Bright, smooth cold-rolled finish obtained by skin pass rolling of No.2D. Specified for general use. |
| No.3 |
lntermediate polished finish obtained with rather coarse abrasives (#100 to #120 mesh). A hjgher luster can be attained by further polishing after fabrication. |
| No.4 |
A standard polished finish produced with finer abrasives (#150 to #180 mesh). Widely specified for restaurant and kitchen equipment and dairy processing equipment. |
| #240 |
Polished finish of about #240. Used when finer finish than No.4 finish is desired such as in equipment for restaurants and house hold kitchens. |
| #320 |
Polished finish of about #320. |
| #400 |
High luster finish produced by polishing No.2B with #400 buffing sisal cloth. Suited for general use. |
| HL |
Special polished finish having continuous lines produced with abrasives of an appropriate grain size. Mainly used in architectural applications. |
| BA |
Highly reflective finish produced by cold rolling, bright annealing and temper rolllng. Used where a lustrous surface is required. |
| Remarks: Upon request, strip surface protection is provided with bonding of vinyl sheets. |
