Anodizing

Clear Anodized Finish

Flannery offers several different finishes for its aluminum trims. The standard Flannery finish is Clear Anodized (Architectural 200R1). The Clear Anodized finish is an electrochemical conversion process that deposits an oxide film on the aluminum trim. A natural oxidation process occurs on bare aluminum, however producing the oxidation process artificially creates a thicker, harder, and more durable “oxide film.” Clear Anodized is an extremely durable finish and is resistant to most forms of corrosion. Please Note: Clear Anodized Finishes can vary from one piece of trim to another. This is one of the charecteristics of the anodizing process and must be considered before any orders are placed.

Special Color Anodized Finishes

Special Color Anodized finishes are also available if required. Gold Anodized, Black Anodized, and Bronze Anodized finishes can be ordered. Bronze Anodized can be ordered in three different colors, Light, Medium, and Dark. Please note: Color Anodized Finishes can vary from one piece of trim to another. This is one of the characteristics to the anodizing process and must be considered before any orders are placed. Typically, the color of the anodizing will fall within a certain range, which usually can be determined prior to anodizing. Check with Flannery for details.
