Grade 304 Stainless Steel sheet is a popular and versatile cold rolled product that is available in a choice of surface finishes. On this page, we will be looking at Grade 304, with a Dull Polished surface finish on one face of the sheet only – the description of this sheet is often shortened to “304 DP1”.
A Dull Polish is also often referred to as a Satin Finish, or a Brushed Polish, typically because of the lines of the grain that run along the length of the sheet. These are somewhat similar (although in this instance they are completely uniform along the length of the sheet) to brush marks that may be visible on paintwork.Read More
Although there are various types and standards of Brushed Polish on the market, all the sheets that we supply are finished with a #4 240 Grit polish. This leaves a finer, tighter & smoother grain when compared to the standard architectural 180 Grit polish. As a result of the finer polish, there are less imperfections in the sheet in which bacteria can sit and therefore the 240 Grit finish is also often referred to as the Dairy Finish or the Sanitary Finish.
As standard, the Satin Polish is only applied to one side of the sheet. Once polished, this face of the sheet is then covered with a layer of PVC which is designed to protect the polished surface from becoming scratched during the handling, storage, cutting and shipping processes. Once you have taken delivery of your sheet, the PVC coating is easily peeled off revealing that lovely smooth brushed finish. The reverse of the sheet comes with a 2B finish but is not PVC coated and therefore scratching on this face is to be expected.
304 DP1 Stainless Steel Sheet is FDA approved and therefore it is most commonly found in areas where hygiene of utmost importance.
Firstly, if you look in your kitchen you may find examples of Brush Polished Stainless Steel sheet on the front panels of your cooker, on your cooker hood / extractor unit or most commonly on the Splashback behind your cooker. These items can also be manufactured from grade 430 stainless steel; however, this is an inferior grade when compared to grade 304 (aka 18/8) and over time items manufactured from grade 430 stainless steel that are regularly exposed to moisture – for example steam – will begin to corrode & rust, which is not quite so hygienic!
