Coloring of Stainless Steel
Colored stainless steels are not only lustrous but also corrosion and weather resistant. The coloring is achieved through application of a chromium oxide layer; this layer is actually an extension of the substrate precluding any possibility of de-lamination. A variety of colors can be achieved that exhibit hardiness and a life span second to none. Originally implemented for automotive concerns the possibilities of this finish have lent it to various additional markets including large-scale architectural paneling and roofing.
Coloring of Aluminum
We specialize in two techniques of coloring that can be conducted on Anodized aluminum, dye and electrolytic (two step).
Anodizing aluminum creates a uniform sealed oxide film over raw aluminum; however, colored dyes can be deposited inside this oxide layer prior to sealing. A great deal of innovation in the past decade has yielded a wide range of dyes, which can suit virtually any application.
Using an electro chemical bath, microscopic amounts of tin is deposited inside the oxide layer providing a range of durable colors. This two-stage process in our facility can yield a range of browns and bronzes as well as black.
