4 "Brushed" finishes. This finish provides a nice bright, brushed appearance that will withstand daily use and mask the fingerprints, scuffs, scratches, etc. A bright, cold-rolled finish is the most commonly "Mill" finish for light gauge stainless steel sheet.
What is a #4 polish on stainless steel?
Stainless steel with a No. 4 finish is attained by mechanically polishing the metal with fine abrasives belts to remove minimal amounts of metal from the surface. The resulting appearance has short, parallel lines for a linear effect.

What grit is used for abrasive finish?
The higher the abrasive grit used, the finer and more reflective the look. For example, one common applied finish is #4, which you will find on your average restaurant or kitchen equipment, food processing or dairy equipment, and elsewhere. This finish uses between 120 and 320 abrasive grit, depending on the application. For comparison, applied finish #3 uses between 100-120. The level of the grit impacts the surface roughness, which is typically measured in terms of micro-inches or micro meters, represented as Ra (roughness average). The higher the grit numbers, the finer the polishing lines and more reflective the finish.
What is pit free finish?
These types of finishes use an intense polishing method to eliminate any unseen pits, scratches or imperfections. Eliminating these imperfections early could also make the finished product is easier to clean, without the need to use harsh chemicals to eliminate that bacteria that develops. Check out more about what it means to create a pit-free finish from Guy Metals, part of the Ryerson Family of Companies.
What is applied finish?
Applied finishes may further enhance the surface appearance and environmental performance of your product. This requires physical alteration of the metal, most notably through the use of abrasive material that removes portions from the surface. The higher the abrasive grit used, the finer and more reflective the look.
What is the final step to ensuring your stainless steel is truly complete?
In the end, determining your finish and the specific needs of your application and properly conveying those to your producer could be the final step to ensuring your stainless steel is truly complete.

What is the grit number of a No. 4 finish?
No. 4 finishes show an Ra of 25 micro-inches or less with a highly reflective finish. Similar to No. 3 finishes, No. 4 finishes are used for general purposes.
What is a No 3 finish?
No. 3 finishes are a 120-grit option. They obtain a 120-grit abrasive through a one-directional course. This type of finish is also known as grinding, roughing, or rough grinding given its coarse, preliminary finish. The intermediate polished finish ensures a peel-off protective covering on one side of the sheet. Using an initial 50- to 80-grit abrasive to achieve a final 120-grit abrasive, No. 3 finishes require mechanical or gradual finer polishing techniques via special coils or rolls. The resulting polishing lines indicate linear grain pattern with a roughness average (Ra) of less than or equal to 40 micro-inches and a moderate reflective finish. Operators must use short strokes in an elliptical motion to create these short grain patterns. No. 3 finishes are commonly used in food production and food service. This includes brewing equipment, food processing, kitchen equipment, and scientific apparatuses.
What is a 2B stainless steel finish?
No. 2B is one of the most common stainless steel finishes used today. It’s a cold roll finish that’s non-reflective, smooth, and has good flatness. Often, the surface has a smooth, reflective grey matte finish, meaning it’s dull and unreflective in appearance. This makes it perfect for applications requiring a basic and unaesthetic finish. With that, 2B finishes are often the least expensive available option. In this case, the thickness can range based on skin passing capacity. To produce a No. 2B finish, stainless steel is cold rolled through a special roller. This produces a smooth, less pitted surface. Then, the surface is softened and descaled in an acid solution. Finally, it passes through polishing rolls for further smoothness. The most common applications for No. 2B finishes include chemical and pharmaceutical equipment, laundry and dry cleaning, refrigeration, and sewage.

How many grits does a flap wheel need to scratch?
Note: This step sets the initial scratch using either a flap wheel or a coated abrasive belt between 60-120 grit, depending on the existing finish. Belts attached to an inflatable or expandable drum will create a deeper scratch than the flap wheel, but either will work.
