The invention provides an alumetizing, anodizing and coloring method for a wind guiding handrail and relates to the technical field of bridges and balding supports. The method comprises the followingsteps: alumetizing the wind guiding handrail; anodizing the wind guiding handrail, wherein a sulfuric solution is used as an electrolyte; cleaning the wind guiding handrail, wherein the wind guiding handrail is cleaned and aired by deionized water to obtain an anodized aluminum film of a crystalline state structure on the surface of the wind guiding handrail; and coloring the wind guiding handrail, wherein a coloring liquid is dissolved, the concentration is controlled at 5-10 g/L, the PH of the coloring liquid is adjusted by acetic acid and ammonia water, and the PH is controlled between 3.5and 6. The method improves the corrosion resistance of the wind guiding handrail, and the wind guiding handrail is high in color firmness and lightfast degree, short in implementing period, high in efficiency, low in energy consumption, low in cost, environmental-friendly and easy to achieve scale and benefit.
