Polished Metals vs. Unpolished Metals

If you’ve looked at the services listed out on our website before, you’ll notice that one of them doesn’t quite fit in with the others. While many of our services revolve around shaping and forming metal to exact dimensions, there’s one that doesn’t accomplish either of these; metal polishing! At its surface, it doesn’t sound like that important of a service to improve your metal. But, did you know that metal polishing can make your metals better and stronger than unpolished ones? We go into more detail as to how polished metals differ below!

Corrosion Resistance

Did you know that polished metals have a higher corrosion resistance than those that aren’t? Corrosion in metals is caused by a process called oxidation, where molecules of oxygen attach themselves to a metal and become capable of breaking through its surface. Part of the process of metal polishing is getting rid of these molecules. This means that metals that are polished corrode at a much slower rate than those that aren’t. Metal polishing can increase the duration of your metal’s life!

Damage Resistance

Corrosion isn’t the only thing that metal polishing services can protect against! Polished metals also have sturdier defenses from the general wear and tear that comes from their uses. The process of oxidation also adds a protective layer to your metal that makes it less susceptible to damage like bumps, scratches and other abrasions. This helps to ensure that your application won’t need to be repaired as often. Unpolished metals don’t have this resistance and therefore will need more treatment to maintain form.


Polished metals are even easier to clean than unpolished metals! The increased corrosion resistance that polishing provides makes your metals much stronger against the chemicals that reside in cleaning agents. These smoother surfaces also make it much harder for harmful bacteria and germs to latch onto them, meaning that you won’t need to clean your metals as often. Polished metals can prevent the spread of disease and also require less maintenance to keep in order.
