The Sub-One name derives from the scientific description of surface smoothness. A surface with a roughness coefficient lower than 1.0 microinch (or sub-one) is extremely smooth and highly desirable for many processes today. Sub-One’s unique, patented InnerArmor technology can apply coatings that are not only extremely smooth and hard, they are also exceptionally resistant to corrosion, erosion and wear. These multi-layer coatings are amorphous, pinhole-free and naturally self-leveling—even across extended lengths.
Sub-One has developed a patented process as well as state-of-the-art systems for depositing its advanced coatings onto the internal surfaces of a broad spectrum of products. These products can range from small, complex components to long, large-diameter industrial piping. Pipe coating and combating pipeline corrosion are, in fact, among the largest applications for this technology.
