An apparatus and method for electro-depositing of a material on at least one side of a metal strip. The apparatus includes at least one casing having a first container section adapted to store under pressure a liquid including the material, a second container adapted to receive a portion of the liquid from the first container section, and a panel. The panel includes an active portion that is electrically polarized at a first polarity, at least one first outlet through which the liquid stored under pressure in the first container section is output in a direction toward the metal strip when the metal strip is conveyed past the panel, and at least one second outlet through which the liquid stored in the second container section is output in a direction toward the conveyed metal strip. The first outlet can be a slit which extends at an angle with respect to the direction in which the strip is conveyed, and the second outlets can be slits which extend traverse to the direction in which the strip is conveyed. The apparatus includes guiding rollers which guide the strip past the panels of the casings, which can be configured in pairs to coat both sides of the strip, or singularly to coat only one side of the strip. The initial guiding roller is electrically polarized at a polarity opposite to the polarity at which the panels are polarized to thus polarize the strip at that opposite polarity.
