NO.4 Surface HL Finish 304 Stainless Steel Plate CR Sheet Hairline
No. 4 Finish is characterized by short, parallel polishing lines
extending uniformly along the length of the coil. It is obtained by
mechanically polishing a No. 3 finish with gradually finer
abrasives. Depending on the requirements of the application, the
final finish can be anywhere between 120 and 320 grit.

1. No 4 finish stainless steel is the workhorse of the light
fabrication industry. The easiest of the finishes to maintain, No 4
finish is used for work surfaces, handrails and where appearance is
important.
2. A 'No 4' surface is produced by cutting the surface with
abrasive belts to remove a very small amount of metal without
affecting its thickness.
For architects and designers, No 4 finish gives low gloss and best
apparent flatness of panels. For fabricators, the No 4 finish is
directional, allowing easy matching of surfaces and refinishing of
welds. For end users, the surface can be repaired to remove any
service damage.
3. No 4 finish is duller than the other common finishes, 2B and BA
and is generally used where lower reflectivity or gloss is required
and where welds and other fabrication marks are to be refinished to
match the original surface. This is not possible with 2B and
difficult with BA.
