In the selection of solar photovoltaic brackets, steel and aluminum have their own advantages and disadvantages, and the choice should be based on specific circumstances.
The advantages of steel brackets are high strength, strong corrosion resistance and relatively low price. The disadvantages of steel brackets are that they are heavy, easy to rust, and difficult to install.

The advantages of aluminum supports are light weight, strong corrosion resistance and easy installation. The disadvantages of aluminum brackets are that they are not as strong as steel and the price is relatively high, but they are worth it.
Therefore, when selecting solar photovoltaic supporting materials, careful considerations should be made based on the installation environment.n specific, budget, installation difficulty and other factors. Generally speaking, if the installation environment is harsh and the bracket needs to have higher strength and corrosion resistance, you can choose steel bracket; if the installation environment is relatively good, you can choose aluminum bracket; At the same time, you should also consider factors such as budget and installation difficulty to choose the most suitable backing material for you.
The shape can be changed and the color generally does not fade. If sprayed on steel, the coating may peel off and rust over time, of course affecting the strength of the aluminum. Alloys also have a drawback: they are afraid of acid. Aluminum alloy will become brittle when exposed to acid. Additionally, if the aluminum alloy is to achieve the same resistance than steel, it must be thickened, which indirectly increases the cost.
