Oxidation process.
This finish is achieved through an oxidation process to develop its distinctive tone. As a result, it is more susceptible to immediate surface corrosion and natural variations in appearance.
Material characteristics.
Oxidation may occur on ferrous metal components as part of the natural aging process of the material.
Texture availability.
This finish is available exclusively in a smooth texture.
Protection coating.
Permalac protection slows down the aging of the finish but highlights imperfections that are not apparent to the eye.
