Surface Treatment

On automotive parts, usually rust preventive surface treatment is applied. Zinc based plating or nickel based plating is often used since they have very reliable performance among various treatment methods. Inside and/or outside surface(s) of USUI made tubes are treated, according to the applications, by proprietary zinc based or nickel based plating.
