No. 6 Finish is a dull, silver white finish with relatively short linear polishing lines.The No. 6 finish has a lower reflectivity than No. 4 finish, and is produced by Tampico brushing a No. 4 finish sheet in an oil and abrasive medium. This finish often used for stainless steel architectural projects between the 1930 – 1980’s. It is no longer produced by toll polishing houses, but custom fabricators sometimes apply it to small projects.
