Mainly used to produce aluminum profiles Our PV mounting systems. Compared with aluminum galvanized steel has the following advantages:
l Light weight
Aluminum density of 2.7kg / dm3
Iron density 7.9kg / dm3
l natural anti-corrosion
Aluminum can be placed in the air at the surface to form a dense protective alumina layer, the protective layer to prevent further oxidation of aluminum.
l anti-galvanic corrosion
When the steel supports photovoltaic panels in contact with the aluminum frame, aluminum solar frame prone to galvanic corrosion, while aluminum bracket is to avoid this phenomenon.
l Balanced Voltage
Aluminum has excellent electrical conductivity, and therefore better able to conduction PV mounting system for various reasons arising from weak current.
l easy to shape
Different molds can be used easily by extrusion process to obtain different cross-sectional shapes of aluminum products.
l easy processing
Aluminum can easily by sawing, drilling, punching, folding and other processing to desired specifications, and process energy consumption is much lower than steel.
l low temperature
Common steel welding area especially vulnerable to low temperature environment is fragile, but the strength of aluminum is actually increased.
l Environmental easy recovery
After reshaping aluminum recycling consume only original profiles from aluminum ore to process 5% of energy.
