  • Publication number: 20130153077
    Abstract: Disclosed is a metal pipe which is for vehicle piping and which exhibits high corrosion resistance without the corrosion resistance being strengthened by means of a coating or a resin coating-layer, due to a hot-dip plating coating-layer being formed by applying a hot-dip plating to the pipe. The disclosed metal pipe for vehicle piping has a plating coating-layer formed on the surface of a formed metal pipe, said plating coating-layer being formed by means of hot-dip plating on the surface of the metal pipe, and the plating coating-layer being formed from a hot-dip plating alloy comprising at least 3 weight % Al, 1-15 weight % Mg, and Zn and unavoidable impurities as the remainder.
