The present invention discloses a photovoltaic plate frame corrosion resistance treatment method, which is used for surface corrosion resistance treatment on a photovoltaic plate frame and sequentially comprises washing, drying, hot zinc plating, and cooling, wherein the washing step sequentially comprises degreasing, inspection, acid washing, and water washing, the degreasing step is adopting a water-based metal degreaser to carry out an oil removing treatment on the photovoltaic plate frame surface, the hot zinc plating step comprises heating a zinc liquid to a temperature of 455-480 DEG C, placing the photovoltaic plate frame into the zinc liquid, maintaining for 1-1.5 min, and taking out, the zinc liquid contains 0.07-0.1% by mass of aluminum, and the leaching assisting step is set between the drying step and the hot zinc plating step. According to the present invention, the process route is simple, and the photovoltaic plate frame surface corrosion resistance quality is easily achieved.
