When we inquire about the purchase of photovoltaic supports in the market, we usually see two materials: aluminum alloy photovoltaic supports and steel supports. When considering which one to adopt, we usually compare whether the strength of the two supports can meet the wind, snow and other requirements, and whether the anti-corrosion performance and price can meet the budget. So who is better between aluminum alloy photovoltaic support and steel support?

1. According to the strength analysis, the strength of aluminum alloy (generally selected aluminum alloy model 6063-T5) is weaker than that of steel (Q235B). Therefore, in terms of wind strength requirements or practical application of photovoltaic support with large span, it is recommended to select steel support to meet the needs of strength, while aluminum alloy photovoltaic support is mostly used in general areas.

2. Anti corrosion performance. Generally, the surface of steel support is hot-dip galvanized, which is generally required to be 65 μ Above, under normal circumstances, it can guarantee the service life of 20 years, but it needs regular maintenance. The surface of aluminum alloy photovoltaic support is anodized to form a dense oxide film. The anti-corrosion performance is higher than that of steel support, and the surface aesthetics of aluminum alloy is also higher than that of steel support.

3. In terms of price, if you want to use aluminum alloy photovoltaic support under the condition of high strength requirements, you can only meet the requirements by adding materials. The price of aluminum alloy in the market is about three times that of steel support. Therefore, the cost of aluminum alloy support will be much higher than that of steel support. In the case of general strength requirements, such as color steel tile roof photovoltaic support, the span is usually relatively small, so the strength requirements are not high. The selection of aluminum alloy support meeting the strength is basically close to the steel support in cost. Moreover, due to the difference of processing technology, the diversity of section of aluminum alloy support can make the aluminum alloy support rich in forms and convenient installation.

The above is the product performance introduction of aluminum alloy photovoltaic support and steel support. When we choose which one to use, we should choose according to the actual site conditions.
