Benefits of Metal Polishing


Abrasive wheels are used to polish and smoothen the metal surface. This technique also helps in removing scratches, imperfections, and tarnishes.

Protective Layer

Polishing offers improved surface quality. Polished metal crafts perform and appear better compared to non-polished ones. This technique helps resist contamination and oxidation which eventually creates premature corrosion.


A polished metal surface creates a shiny finish which results in an effective light reflection. This property is beneficial for architectural elements jewelry, and other decorative items.


Metal polishing improves functionality in specific applications like machinery components. The polishing technique eliminates surface imperfections giving a smooth and even finish. This also reduces friction which improves the overall performance.


The metal polishing technique gives an appropriate finish that prevents the risk of germs and bacteria. The finish that this technique creates allows efficient cleaning time.

After knowing the advantages of metal polishing, we can now move on to the different finishes it offers.


Different Metal Polishing Finishes

Brushed Finish – This metal polishing technique produces a pattern that consists of parallel lines. The brushed finish is ideal for outdoor and indoor applications where exposure to sunlight is expected.

Brushed Finish

Satin Finish – A standard type of metal polishing technique that offers a toned-down appearance. This polishing finish results in a smooth and more subtle appearance suitable for home appliances and architecture.

Different Stages of Metal Polishing

Polishing has four different stages. Each stage requires different tools and materials. Each stage is not necessary to be applied on the same workpiece. However, the polishing stage to use will depend on the required finish.


This stage is used to remove traces of dirt, dust, or any impurities acquired during the previous process. Grating is used on jewelry pieces with a coating of gold or silver.



Roughing is also called sanding. This stage involves removing of defects by using a course material to show a smooth surface that’s free of imperfection.



The grinding stage is essential in removing marks left by the roughing stage.



The polishing stage removes the marks left by the grinding process. When polishing is finished, the metal craft is ready to be given the desired finish.



This stage is used to restore the shine of the metal surface and give it a uniform finish. Glossing is applied to parts that will not have any metallic coating.



How Do Metal Polishing Works


Polished Metal Vs Unpolished Metal


Corrosion Resistance

Compared to non-polished metals, polished metals have more protection against rust and corrosion.


Compared to non-polished metals, polished metals appear to be more reflective and overall have a bright finish.

Polished Vs Unpolished


A polished metal when compared to unpolished metal has an improved overall functionality. By polishing, the imperfections on the metal surface are eliminated.


A polished metal features an appropriate finish that prevents the risk of germs. Metals that have been exposed to gems have a potential risk of damage. In addition, compared to unpolished metal, polished surfaces can be easily cleaned.
