What issues should be paid attention to when selecting solar photovoltaic brackets

Secondly, anti-corrosion performance is also an important parameter of photovoltaic brackets, because the quality of anti-corrosion not only affects the service life of photovoltaic power stations, but also affects the appearance of brackets. Usually, the surface of steel brackets is treated with hot-dip galvanizing, which is generally required to be above 65μ. Under normal circumstances, it can ensure a service life of 20 years, but regular maintenance is required. The surface of aluminum alloy brackets is anodized to form a dense oxide film, and the anti-corrosion performance is much better than that of steel brackets. In addition, the surface aesthetics of aluminum alloy photovoltaic brackets is also better than that of steel brackets.

Finally, comparing the prices of the two, if the strength requirements are relatively high, if aluminum alloy photovoltaic brackets must be used, the requirements can only be met by increasing the material. The price of aluminum alloy on the market is about 3 times that of steel brackets. Therefore, the cost of aluminum alloy photovoltaic brackets will be much higher than that of steel brackets. In the case of general strength requirements, such as color steel tile roof photovoltaic brackets, the span is usually relatively small, so the strength requirements are not high. The cost of using aluminum alloy brackets that meet the strength is basically close to that of steel brackets. In addition, due to the difference in processing technology, the diversity of the cross-section of aluminum alloy brackets can make aluminum alloy brackets rich in form and easy to install.
