1 Stainless Steel – Surface Finishes Introduction Finishes and Fabrication Surface finish is an important element in any Some fabrication operations, such as grinding specification of stainless steel regardless of the prior to painting or gluing, may require a rough intended use. For those applications where surface finish but, generally speaking, a appearance is important, finish is a design smooth, well finished sheet requires less element and must be specified. In non- physical effort than a coarse, rough one when it decorative applications the surface finish may comes to blending. Certain finishes are more have implications for friction, wear, difficult to recreate by hand than others, maintenance or corrosion resistance and must, causing fabrication difficulties; this is especially therefore, also be carefully chosen and clearly true of the “special” finishes which cannot be specified. easily replicated in a fabrications workshop. For The choice of finish should never be left to the this reason the fine satin finish (such as supplier, or the specification loosely worded, OPTISHEEN®) is popular and practical for such as “Type 304 with a 180 grit finish”. The fabrication shops around the world. finish should be properly identified by a standard industry designation or by a trade Types of Finish name, e.g. OPTISHEEN®. Stainless steel is available in a wide variety of standard and special finishes. The majority of Finishes and Design finishes can be divided into three categories:
