There are a lot of trade-offs when choosing a photovoltaic bracket. In the end, you have to choose between a steel bracket and an aluminum bracket. Which one should you choose? This has to start from the advantages and disadvantages of the steel bracket and aluminum bracket.

Let’s compare the strength of the materials first. It is found through experiments that generally in strong wind areas, steel supports are better than aluminum alloy supports. Secondly, for the deflection and deformation of the two, these are related to the shape and size of the material, the elastic modulus, etc., so it can also reflect the performance of the material.

In addition, the steel is hot-dip galvanized 55-80μm, and the aluminum alloy is anodized 5-10μm. In this regard, the aluminum alloy is far superior to steel. After a comprehensive comparison, the aluminum alloy bracket and the steel bracket are very good bracket products, and are suitable for different occasions. For example, the steel bracket is suitable for ordinary power stations, and the aluminum alloy bracket is suitable for rooftop power stations.
