Finishing Your Product Before It Goes Out Our Door

Mechanical Finishing

These methods can give aluminum extrusions and other products several different types of surface texture from rough or patterned to a mirror finish. If your product design requires a final surface finish, improved surface quality, or to prepare for various final cosmetic finishes, consider the following types of mechanical finishes.


An attractive cosmetic surface finish that replicates polished chrome. Buffing is a secondary operation.


Brushed finish is cosmetically appealing and looks like stainless steel. Brushing is beneficial for blending extruded die lines and covering imperfections. It is available in a wide range of textures. Brushing is a secondary operation that provides a perfect solution to your aluminum surface finish needs.

Bead Blasting

Bead blasting produces a unique granular appearance with a wide range of textures. This type of mechanical finish is an outside operation.


A tumbled finish has a galvanized appearance with the degree dependent on the media and time involved. There are currently a wide variety of tumbling media available. The entire part is tumbled, which eliminates the swirl marks resulting from normal end-brush deburring machines. Tumbling also eliminates flow lines from the extrusion process. This type of mechanical finishing can serve multiple purposes such as deburring, washing, and polishing.

We are happy to discuss each of these surface finish options with you in detail. As we learn more about your project needs, you will be assured that we will do whatever we can to make sure your final product is the best it can be.
