Anodizing

Anodizing at volume, with color held consistent from first article to final pallet.

01 · Anodization

Color grown into the metal

Anodizing is an electrochemical process that grows a hard oxide layer into the surface of the aluminum, then seals dye inside it. Because the color lives in the metal rather than on it, it cannot chip, peel or scratch off. Our patented system ensures a tightly controlled color range from first piece to last.
