Mechanical processing and finishes

The aluminum extrusions produced by Profilati Alluminio can be furnished with untreated surfaces, or else with various surface finishes. The latter can essentially be grouped into two main categories:

• anodised finishes
• surface coatings

Aluminum extrusions with anodised surfaces

Aluminum extrusions with anodised surfaces are recommended whenever greater protection is required against potentially harmful external agents. Anodisation is a galvanic, or electrochemical, process that creates a layer of oxide on the surface of the extrusion. This layer serves to protect the metal against the harmful effects of the atmospheric agents, as well as to give it a certain colouration, which can either be neutral or else a variety of bronze shades, ranging from light (champagne) to dark.

Aluminum extrusions with coated surfaces

Aluminum extrusions with coated surfaces, on the other hand, are recommended whenever certain aesthetic requirements need to be met. Coating is a process by which a layer of coloured material is deposited upon the surface of the extrusion. These normally consist of epoxy or electrostatic polyester powder coatings, which adhere well to the metallic surface and must be subjected to a secondary treatment in order to render the coating layer itself uniform.

Our coated extrusions in aluminum can be furnished in all the RAL colours, and can even be produced with special aesthetic effects, like the wood effect. These are particularly popular in the furnishing and technical furnishings industries.
