What is stainless steel black coloring?
By adopting new electrolytic coloring technology, we have achieved a deep black color while still taking advantage of the metallic feel.
Unlike plating or painting, this coloring technology involves growing an extremely thin black oxide coating on the surface of the material and using the interference of light to make the color visible, so there is no need to worry about it peeling off, and it is a coloring technology that is "black on its own" and has excellent durability and weather resistance.
While retaining the original texture of the metal, the timeless black color enhances its status by providing the ultimate in solidity, functionality, and design.
