Surface finish is regarded as an important part in any kind of specification of stainless steel. For different types of applications where appearance or looks play an important part finish is regarded as a design element and this must be given special attention. In non-decorative applications where looks or appearance is not more important, good surface finish is considered as an important part because it saves the object from general wear and tear, friction etc. Good stainless steel finish is significant because of its low maintenance and corrosion resistance. Thus, it should be chosen carefully and should be specified in proper way.
The selection of stainless steel finish should never be left to the supplier alone. The stainless steel finishes should follow the instructions and specifications by a standard industry designation.

In fact, smoother surfaces are generally less susceptible to any form of deposit build up. Stainless steel finishes generally have better performance than other type of product especially for the highly visible applications; the appearance of stainless steel is extensively used for applying critical designs.
Different types of finishes and fabrications:
Some fabrication processes include painting and gluing that may require a rough surface finish. However, a smooth and well finished surface requires less physical effort than the coarse or rough surface materials. In certain cases, satin finishes can be applied because of an improved visual outlook.
Different types of mill finishes:
