Anodizing is an electromechanical process whereby aluminum is placed in a water and sulfuric acid bath while exposed to positive and negative electrical charges. The process causes a conversion of the molecules on the architectural grille’s surface which adds a thin protective layer of anodic material.
The change in surface material proves a durable, corrosion-resistant, easy-to-clean, decorative finish that gives anodized aluminum grilles a rich character.
An anodized finish is not preferred when your architectural grilles will be used in a moisture rich environment, on a window or sill exposed to sunlight (UV light), for outdoor applications or for a floor grille or register which may be exposed to foot traffic or cleaning solvents.
The Advanced Architectural Grilleworks team can provide various anodized finishes including clear satin anodized, black satin anodized, and bronze duranodic anodized in light, medium and dark shades which provides a look similar to bronze statuary finishes. Typically the anodized finishes do not possess the same rich character as actual architectural bronze, though they offer an economical budget alternative.
