UNPOLISHED OR ROLLED FINISHES:

No. 1   A rough, dull surface which results from hot rolling to  the specified
        thickness followed by annealing and  descaling.

No. 2D  A dull finish which results from cold rolling followed by  annealing
        and descaling, and may perhaps get a final  light  roll pass through
        unpolished rolls.  A 2D finish is  used  where appearance is of no
        concern.

No. 2B  A bright, cold-rolled finish resulting in the same manner  as No. 2D
        finish, except that the annealed and descaled  sheet receives a final
        light roll pass through polished  rolls.  This is the general purpose
        cold-rolled finish  that can be used as is, or as a preliminary step
        to polishing.

No. 2BA
  or BA Non-standard but widely offered bright annealed finish,  highly
        reflective surface.

POLISHED FINISHES

No. 3   An intermediate polished surface obtained by finishing  with a 100-grit
        abrasive.  Generally used where a  semifinished polished surface is
        required.  A No. 3 finish  usually receives additional polishing during
        fabrication.

No. 4   A polished surface obtained by finishing with a 120-150  mesh abrasive,
        following initial grinding with coarser  abrasives.  This is a general-
        purpose bright finish with a  visible "grain" which prevents mirror
        reflection.

No. 6   A dull satin finish having lower reflectivity than No. 4  finish.  It
        is produced by Tampico brushing the No. 4  finish in a medium of
        abrasive and oil.  It is used for  architectural applications and
        ornamentation where a high luster is undesirable, and to contrast with
        brighter finishes.

No. 7   A highly reflective finish that is obtained by buffing  finely ground
        surfaces but not to the extent of completely  removing the "grit"
        lines.  It is used chiefly for  architectural and ornamental purposes.

No. 8   The most reflective surface, which is obtained by polishing with
        successively finer abrasives and buffing  extensively until all grit
        lines from preliminary grinding  operations are removed.  It is used
        for applications such  as mirrors and reflectors.
