To provide an outdoor installed metal post capable of preventing a post of safety facilities already installed along a road from being corrodes with a sprayed snow-melting agent and also capable of being easily installed at a site with high rust-preventive performance.

A near-ground surface of the post 1 of safety facilities is partially 4 or totally coated with a thermal spraying resin film. The thermal spraying resin film is formed by a multi-layered resin film in which a different kind of resin materials with high melting temperature are sequentially thermal sprayed and piled up from a lower layer to an upper layer.
