Non Polished MS Stainless Steel Sheet, Width : Custom

The grades and surface finish of stainless sheet is very varied, the basic sheet from the mill where the sheet is produced generally has a plain grey appearance which is designated 2B. This is the starting point from which all the other finishes begin.

Embossed patterns are generally rolled into the sheet, this is called rigidised stainless steel. Mirror finishes are achieved by either a mechanical or chemical process. Brushed finish is a mechanical process.

Both Mirror and brushed finished are referred to in the trade as Polishes.

The finish referred to as “Brushed Finish” has a trade reference “DP” which means “Dull Polish”. This finish is achieved using grit in the polishing media. Variations in the brush effect are obtained by using grits of different sizes.
