How do anodization affect solar racking performance
We all know that the performance and service life of solar racking are directly related to the benefits of solar power plant. Due to long-term exposure to wind and sunlight, it’s necessary to consider the corrosion resistance and hardness of the solar racking. In order to meet a certain standard, companies will choose different surface treatments, such as anodization, electrophoresis coating, powder coating, etc. One of the most widely used is anodization, so why does it become so popular? The anodized aluminum profiles will forms an oxide film on the surface, which provides strong and effective corrosion protection. In addition, the anodized film has higher hardness, which greatly improves the wear resistance of aluminum profiles. The oxide film thickness of aluminum profiles is mainly divided into 4 grades, namely AA10, AA15, AA20, AA25. That is to say, its average film thickness should be 10μm, 15μm, 20μm, 25μm, and the local thickness is not less than 8μm, 12 μm, 16 μm...
