Metal Finishing Techniques: Polishing, Powder Coating, and More

January 24, 2024
Quality Metal Fabrication And Finishing In Toronto

Metal fabrication in Toronto is an essential component of construction, be it residential or commercial. However, once the fabrication is finished, the end product requires additional processing in the form of metal finishing. Metal finishing is defined as the process of improving the surface of the metal through a series of techniques such as polishing, powder coating, and more. In this blog, Weld Rich & Steel Inc., manufacturers of custom metal fabrication in Toronto, define 5 major metal finishing techniques.


5 Popular Metal Finishing Processes




In this method, abrasive materials are used to grind or polish the fabricated metal surface. This removes any bumps or irregularities on the surface and makes it smoother. It can also improve the cosmetic appearance of the metal or alloy, making it a basic metal finishing technique employed for most metal parts.




Another simple and cost-effective finishing process is coating the metal or alloy’s surface with a layer of paint. Painting can not only make the surface more appealing due to its colour, but it also aids in preventing corrosion.


Powder Coating


Powder coating is a more advanced method of painting/coating, where the metal’s surface is evenly coated with a layer of powder using an electrostatic charge. It is a fast and completely effective method that is ideal for complex metal parts such as automobile frames and structural components. 




Electropolishing is quite similar to electroplating, except the process is entirely reversed. In this method, the metal part or the substrate is immersed in an electrolyte bath. When an electric current is applied to the bath, the substrate turns into an anode, and metal ions are removed from the surface. This, in turn, removes dust, debris, and corrosion from the surface, leaving it smooth and evenly polished. 




Blasting is another excellent metal finishing technique that combines surface cleaning and finishing. In this process, an abrasive spray or stream is applied to the metal surface, effectively removing any impurities and making the texture smooth.
