Available Finishes

We offer a range of modern, minimalist finishes to suit every modern home. From our hand finished Brushed Chrome grilles to our durable Powder Coated and Anodized finishes, we have almost every option to suit your needs.

Brushed Chrome

Glacier Frost

Black Monolith

Anodized Clear

Anodized Light Brown

Wenge Brown

Brushed chrome finishes

Our Brushed Chrome Finish is a hand brushed aluminum finish with a light, oven baked clear coat to prevent fingerprints and scratches. This finish is the most complementary to stainless steel or brushed nickel and satin fixtures.

Powder coat paint process

Our Powder Coat Paint Finishes (Glacier Frost, Black Monolith and Wenge Brown) are extremely durable and resistant to chipping, scratching and corrosion. Our paint systems are extremely flexible, allowing the handling of large single-piece sections of varying size and lengths.

Anodizing process

Our Anodized finishes offer a sleek, satin finish to match modern anodized accents. Anodizing is an electrochemical process that creates a protective coating of aluminum oxide on the surface of our vent covers.

Unlike painting, the anodizing coating is not applied to the surface. Instead the existing aluminum oxide is enhanced and grown out from the aluminum. This creates a surface that is much harder and more resistant to corrosion and abrasion than raw aluminum.
