Aluminum alloy material is the main material of aluminum photovoltaic bracket, which has the characteristics of light material, beautiful appearance, simple and easy assembly, and strong corrosion resistance. Compared with steel photovoltaic supports, aluminum alloy supports have significant advantages of lower cost and longer service life.

1.Lightweight

Density of aluminum: 2.7kg/dm³

Density of steel: 7.9kg/dm³

2.Resisted natural corrosion.

Aluminum placed in air can form a dense aluminum oxide protective layer on the surface, which can prevent further oxidation of aluminum.

3.Resisted galvanic corrosion.

When the steel bracket is in contact with the aluminum photovoltaic panel frame, the aluminum photovoltaic panel frame is prone to galvanic corrosion, while the aluminum bracket avoids this phenomenon.

4.Balanced voltage.

Aluminum has excellent electrical conductivity, so it can better conduct the weak current generated by various reasons in the photovoltaic support system.

5.Easy to shape.

Aluminum profile products with different cross-sectional shapes can be easily obtained by extrusion process using different dies.

6.Easy to process.

Aluminum profiles can be easily processed into the required specifications by sawing, drilling, punching, folding and other processes, and the energy consumption of the processing process is also much lower than that of steel.

7.Low temperature resistance.

Ordinary steel, especially the welding area, is fragile and brittle in a low temperature environment, while the strength of aluminum increases.
