The brushed aluminum plate is a manufacturing process in which the aluminum plate is repeatedly scraped out of the line by sandpaper, and the process flow is mainly divided into three parts: de-esterification, sanding machine and water washing. In the aluminum drawing process, the special film technology after the anodizing process can form a film layer containing the metal component on the surface of the aluminum plate, clearly showing each fine silk mark, and making a fine silky luster in the matte finish.
