1. Natural corrosion

The aluminium placed in the air forms a dense protective layer of alumina on the surface, which prevents further oxidation of the aluminium.

2. Resistance to galvanic corrosion

When the steel support contacts the aluminium photovoltaic panel frame, the aluminium photovoltaic panel frame is prone to electric coupling corrosion, while the aluminium support avoids this phenomenon.

3. Balance voltage

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

4.Easy forming

The aluminum products with different section shapes can be easily obtained through extrusion process with different molds

5. Easy to processing

Aluminum profiles can be easily sawed, drilled, punched and folded into required specifications, and the energy consumption of the process is much lower than that of steel.

6. Good low temperature resistance

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

7.Environmental friendly easy recycling

The recycled aluminium consumes only about 5 percent of the energy used to go from the aluminium ore to the profile。
