Aluminum products are processed by aluminum sheet manufacturers through aluminum anodizing technology, which greatly improves wear resistance, corrosion resistance, light resistance, weather resistance and other properties, and can have a variety of beautiful and bright colors. It adapts to the requirements of the aesthetic feeling of the times, thereby greatly improving the application value of the aluminum plate.

 

Decorative 4 x 8 aluminum sheet building profiles are the main materials for doors, windows and curtain wall structures and are widely used around the world. The aluminum alloy extruded profile (without surface treatment) has a single appearance and is easy to corrode in a humid atmosphere, so it is difficult to meet the requirements of high decoration and strong corrosion resistance of building materials.

 

In order to improve the decorative effect, enhance the corrosion resistance and prolong the service life, the aluminum plate usually needs to be surface treated. Therefore, aluminum anodizing surface treatment is an essential and extremely important process in the production of aluminum alloy profiles. The oxide film formed by anodization of aluminum alloy in -H2SO4 solution is white, transparent, high in porosity and good in chromaticity, especially suitable for aluminum oxidation processing.
