No.4 Finishes

NO4 Finish

A No. 4 finish is sometimes called the workhorse finish, as it is easy to maintain in high-traffic areas such as handrails, kitchen equipment, stainless steel sinks, bus shelters, elevator doors, and work surfaces. 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. No. 4 finished stainless steel will appear different from manufacturer to manufacturer due to different belts and grit sizes, which usually range from 120 to 320 grit, depending on the project requirements. The higher the grit, the finer the lines and the more reflective the surface will be. No. 4 finished stainless steel has a little more finish than stainless steel with a 2B finish.
