Types

• Long Grain (Hairline)

A Long Grain finish, also commonly referred to as a “Hairline” finish is considered a #6 Satin that receives additional polishing in order to give the appearance that the grain runs continuously for the entire length of the product. This particular finish is often applied to a variety of metal types for use in elevators and escalators.

• Non-Directional Satin

A Non-Directional Satin finish is considered a random orbital finish achieved by sanding with coated abrasive pads, with no specific direction of the grain. This particular finish is often applied to a variety of metal types for use in elevators and escalators.

• Cross-Grain Satin

A cross-grain satin finish is achieved by sanding with coated abrasive pads, in a cross-hatch pattern. This particular finish is often applied to stainless steel for use in architectural projects.

• #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.

• #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.

• #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. This particular finish is most often applied to 304 Stainless Steel for use across a wide range of industries.
