An apparatus and method for spray metallizing a coating of metal (e.g., zinc) onto one or both sides of a base metal (e.g. steel). One embodiment of the invention comprises melting the metal to be deposited, propelling first and second streams of the melted metal towards the base metal at a point of convergence adjacent to the substrate, and applying a potential difference between the streams to form an electric arc whereby superheated particles are deposited on the base metal. A second embodiment of the invention comprises melting the metal to be deposited, propelling a stream of the melted metal towards the base metal through a nozzle containing a non-consumable stationary electrode, and applying a potential difference between the molten metal and the electrode to form an electric arc whereby superheated particles are deposited on the base metal.
