Anodized Square Tube profile 

  In the surface treatment technology of aluminum, anodizing has been the most in-depth research and widely used, and was once hailed as a universal aluminum surface treatment technology. The production market prospects of aluminum alloy extruded profiles for building doors and windows are very broad, and aluminum anodizing is widely used in building doors and windows, curtain walls, and other aspects. In recent years, a large number of domestic and foreign practices have proven that aluminum anodizing film may be a surface treatment method to ensure a longer service life of building aluminum profiles. Anodized aluminum alloy products have been developed in automotive components, electronic product decorations, and many functional components. Aluminum surface treatment is an essential process for extending the service life, expanding the application range, and improving market value of aluminum materials. It is an extended process for aluminum alloy processing, and its impo…
