Anodized extruded aluminium tube 

  Before anodizing, aluminum profiles need to undergo sandblasting pretreatment. Sandblasting can remove burrs, casting slag, and other defects and deposits on the surface of aluminum profiles. After sandblasting, aluminum profiles will present a uniform and relatively smooth surface.  Spraying with quartz sand will result in a light gray surface.    Anodized aluminium tube is a type of Standard Aluminum Extrusion Shapes that has undergone anodizing treatment. This material has high corrosion resistance, smooth surface, beautiful appearance and strong hardness.Therefore, it is widely used in industries including construction, decoration and machinery whlie used for a long time in various environments. Anodizing treatment is a common surface treatment method for aluminium profile which can improve the corrosion resistance and oxidation resistance of aluminum materials.This anodizing film not only protects aluminum from corrosion, but also provides better de…
