Stainless steel brushing/polishing

Why it is necessary to process stainless steel?

Sanding and polishing of stainless steel enhance the aesthetic side of the object, while having a practical and protective function.

During sanding and polishing of stainless steel, we reduce the risk of corrosion and make the surface smoother. The smoother the surface of stainless steel, the less dirt and bacteria accumulate on the surface of the metal. By sanding and polishing, we ensure a longer service life of the metal surface.

The quality of polished and sanded stainless steel is assessed by surface roughness. Surface roughness is assessed by the value of Ra, the results of which are usually expressed in micrometres. Ra indicates the arithmetic mean value of the surface irregularities. Rq shows the average value of the highest peaks.

Surface roughness is the depth of the cut marks created by a cutting tool (sandpaper, polishing disc / polishing paste) on the treated surface.

Field of application of stainless steel

Stainless steel is widely used in the food and medical industries. One reason is the fact that the material has antibacterial properties and is durable.

Resistance and protection against bacteria are achieved during the polishing process.

That is why it is very important to find the right degree of surface roughness.

In order to achieve a more shiny and smoother surface, more additional work must be done when processing stainless steel and fine-grained polishing pastes must be used.

It is very important to choose the right finish. You probably want long service life, corrosion resistance and as little maintenance as possible. The right finish ensures that stainless steel behaves as needed.
