What Surface Finishes Can You Apply On An Aluminum Extrusion Frame?

Surface finish is a way of coating the aluminum extrusion frames to protect and enhance the durability of the structure.

The types of surface finish you can use include the following:


This is an electrochemical technique for anodizing aluminum extrusion frames.

Anodizing will form a layer of oxide on the surface of the frame which offers a protective cover.

Besides, there are no extra layers you will add following the anodizing process.

This is because it forms a layer on the original surface of the aluminum and forms strong molecular bonds.

Besides, anodizing will enhance the corrosion resistance of aluminum extrusion frames while still maintaining their appearance.

Besides, you either use hard or natural anodizing processes on aluminum extrusion frames.

In natural anodizing, you will use an anodic film that is transparent and uncolored.

Hard anodizing entails applying oxide layers to form a hard layer on the aluminum extrusion frames.

Bright Dipping

This process entails placing the aluminum extrusion frame in a bright dip to make it have the appearance of a mirror or be specular.

Here, you will place the aluminum extrusion frame in a solution containing both nitric and phosphoric acid.

Once you finish the bright dipping process, you will proceed to anodize the aluminum extrusion frame.

This combination forms a thick oxide layer that will enhance the corrosion resistance of aluminum extrusion frames.

Mill Finish

This type of surface finish forms textures on aluminum extrusion frames after exiting the rolling mills.

The mill will form surfaces that have no luster and is rough, while not involving mechanical or chemical surface finishes.


Here, you will produce a surface finish by conducting cleaning or etching on the aluminum extrusion frame.

To conduct the etching and cleaning process, you will make use of substances such as acids and alkaline.

Once you clean the aluminum extrusion frame, apply a pretreatment to improve the paint or powder.

Conducting this process will increase the corrosion resistance of the aluminum extrusion frame.

Powder Coating

This type of surface finish provides decorative and protective layers on the aluminum extrusion frames.

Besides, you will coat the aluminum through electrostatic technique following a series of pre-treatments such as degreasing.

Powder containing a negative charge will bond with the aluminum extrusion frames with a positive charge.

The electrostatic process causes the powder to form a temporary stick on the surface of the aluminum.

After this, you will cure the aluminum extrusion frame after heating and melting the coat to form a liquid film.

Besides, powder coating is safe to the environment and produces a rough finish due to the visible granules.

Mechanical Finish

The mechanical processes that you will use to improve the surface of aluminum extrusion frames include:

  1. Blasting
  2. Gritting
  3. Buffing
  4. Sanding


This surface finish offers a smooth outlook and is suitable in applications that value aesthetics.

Besides, painting is simple since you will conduct the process within spray booths.


This method is less used but is growing in popularity since it will make the aluminum extrusion frame have the appearance of wood.

Here, you will apply a base powder coat then conduct the extrusion process.

Afterward, you will apply thin films containing patterns on the aluminum extrusion frame.

The wood pattern sticks to the aluminum extrusion frame during the sublimation process.

How Does T-Slot And V-Slot Aluminum Extrusion Frame Compare?
