The invention provides a metal structure coating quality control method. The metal structure coating quality control method comprises the steps of: appearance detection: conducting appearance detection on a metal structure coating through magnifying optical equipment; a thickness uniformity analysis test: carrying out thickness uniformity analysis on a part plating by adopting a metallographic microscope method; a coating binding force test: rubbing the surface of the coating, and/or brushing the surface of the coating by using a fine metal wheel on a brushing machine, and/or heating the coating, and observing whether the surface of the coating bubbles, peels or falls off or not; and a plating porosity test: dripping a concentrated hydrochloric acid solution onto the surface of the coating, and observing whether bubbles appear on the surface of the coating or not. The appearance, the thickness uniformity, the coating binding force and the coating porosity of the metal structure coatingare inspected and subjec
