Satin Finishes

We offer the satin finishes listed below across all metal types. To speak with the Architectural Metal Polishing team about your project, request a quote.

#2B/Mill Finish

The #2B is a lustrous (but not mirrored) finish. #2B is also known as “mill finish” because it describes the unpolished state of the cold rolled material straight from the producing mill. While products with a #2B finish typically exhibit some luster, they are not reflective or mirrored in any way. This finish is typical for very practical applications where the appearance of the metal is not a factor.

#3 Satin Finish

The #3 finish has a wide range of uses across many industries. This finish is achieved by polishing on a wide belt machine, resulting in a coarser appearance. This finish measures between a 60-80 Grit and 50 RA.

#4 Satin Finish

#4 is the industry standard for satin finishes. This finish is similar to #3; however, the final polishing is done using a higher grit of 120-180 and 32 RA Max, producing a smoother, more refined finish. This finish is widely used across many industries, often for stainless steel products.

#4 Long-Grain Finish

Variants of the #4 finish include the same initial procedure used to produce a standard #4 finish, followed by additional polishing to change the direction of the grain. In the case of a long grain finish, this additional polishing gives the appearance of a grain that runs continuously along the length of the product. This is also commonly referred to as a “hairline” finish.

#4 Cross-Grain Finish

Variants of the #4 finish include the same initial procedure used to produce a standard #4 finish, followed by additional polishing to change the direction of the grain. To achieve a cross-grain finish, the product is sanded in a cross-hatch pattern. The difference between cross-grain and other satins finishes is the horizontal direction.

#4 Non-Directional Satin Finish

Variants of the #4 finish include the same initial procedure used to produce a standard #4 finish, followed by additional polishing to change the direction of the grain. By sanding with no specific direction of the grain, this produces a random orbital finish.

#6 Satin Finish

Similar to #4 except an even finer and smoother appearance. After initial polishing, the final finish is achieved by polishing with a 240-320 grit abrasive belt and measures a 20 RA max. This particular finish is most often applied to 304 Stainless Steel for use across a wide range of industries.

#6 Long-Grain Finish

Variants of the #6 finish include the same initial procedure used to produce a standard #6 finish, followed by additional polishing to change the direction of the grain. In the case of a long-grain finish, this additional polishing gives the appearance of a grain that runs continuously along the length of the product. This is also commonly referred to as a “hairline” finish.

#6 Cross-Grain Finish

Variants of the #6 finish include the same initial procedure used to produce a standard #6 finish, followed by additional polishing to change the direction of the grain. To achieve a cross-grain finish, the product is sanded in a cross-hatch pattern. The difference between cross-grain and other satins finishes is the horizontal direction.

#6 Non-Directional Satin Finish

Variants of the #6 finish include the same initial procedure used to produce a standard #6 finish, followed by additional polishing to change the direction of the grain. By sanding with no specific direction of the grain, this produces a random orbital finish.
