RA/RMS is a metered soft satin finish. During the finishing process, measurements are taken of the depth and top of the grain to determine the Roughness Average (RA) or Root Mean Square (RMS) until the overall roughness meets our customer’s specifications.
The industry standard satin finish, #4 satin is used in a variety of industries and applications. The #4 finish gives metal a unidirectional and textured, yet smooth appearance.
This finish is similar to #4 satin, but with an even finer texture for a smoother appearance and brighter sheen. To achieve this finish, the metal undergoes additional polishing with a 240-320 grit abrasive belt, followed by cloth buffing.
A “pre-buff” or “dull mirror” finish, #7 mirror finish creates a highly reflective surface, though not quite as reflective as #8. This is because the surface is finely ground, but grit lines are not removed through a final buffing process.
#8 is the industry standard when it comes to a true mirrored finish. This extremely reflective appearance is created through several stages of directional buffing, as well as a final buff using a rouge compound.
If you don’t see the metal finish you’re interested in for your parts or project, Pride Metal Polishing also provides professional custom metal finishing. Our facility includes industry-leading metal finishing equipment, and we can often match the finishes of samples that are brought to us.
