Three Finishing treatments for Aluminum Profiles

Sometimes a customer may want their surface of aluminum profiles to be extensively finished than is available right after they come from the die. This might simply be to enhance the appearance of the profiles given by the aluminum profile manufacturer, or because the surface of aluminum requires adaptation to the requirements of specific industries like pharmaceuticals or agriculture. Therefore, aluminum profile suppliers offer a wide range of finishing treatments as a component of their aluminum fabrication process.

Aluminum profiles have the ability to be treated with various finishes. The kind of finish selected depends upon the client’s industry and the individual requirements. There are three major kinds of finishes that you can take for aluminum extrusion profiles. Below is some information about each process normally offered to the customers:


Although aluminum proves to be a soft metal, aluminum is an organically durable and strong metal that can withstand any type of significant scrutiny. That molds aluminum into a receptive substance to more mechanical techniques of surface preparation. An aluminum extrusion profile can be altered easily by using corrosive methods like buffing and polishing. These are straightforward processes that are used to brighten the aluminum‘s surface and make it extra appealing.

Aluminum proves to be a metal that bolsters brilliant corrosion resistance, leaving the structural integrity unimpaired by an atmospheric attack. This makes it aluminum a perfect material for anodization. Aluminum is anodized via immersing it in a diluted sulphuric acid container, thickening its organic oxide layer. This can produce an extremely aesthetically pleasing impact along with giving the metal with massive protection.

Apart from wood grain aluminum, anodization finishing can be merged with polishing to make the metal bright and provide it with a mirror finish such as chrome. One of the most inexpensive and popular options is natural satin silver for anodizing aluminum extrusion profiles. However, there is a possibility to do colored anodizing in a broad range of dark colors such as bronze and black to brighter primary colors, gold and the sought-after rose gold.

Powder coating

Lastly, powder coating comes as a surface treatment that is a necessary application of paint without a solvent element. The coating process provides the aluminum profiles with excellent UV protection, making it perfect for profiles for outdoors use such as architectural applications and signage. When applied perfectly, powder coating becomes a quite durable surface treatment and potentially lasting on any surface of the metal for 15 to 20 years.

Wrap Up

Anodizing withstands the ‘metal’ appearance while powder coating covers it. However, the impacts of every treatment must be considered while deciding which finish selecting. It is recommended to consider other factors, such as the life of the treatment and abrasion resistance before going for any surface treatment.
