Photovoltaic bracket material

At present, the solar photovoltaic bracket commonly used in China is divided from the material, mainly there are three kinds of concrete bracket, steel bracket and aluminum alloy bracket.
Concrete support is mainly used in large-scale photovoltaic power stations, because of its self-importance, can only be placed in the field, and the foundation is good, but the stability is high, can support the size of a huge panel.
Aluminum alloy bracket is generally used in civil building roof solar applications, aluminum alloy has the characteristics of corrosion resistance, light weight, beautiful and durable, but its self-bearing capacity is low, can not be applied in solar power station projects. In addition, the price of aluminum alloy is slightly higher than that of hot-dip galvanized steel.
The steel bracket has stable performance, mature manufacturing process, high bearing capacity, easy installation, and is widely used in civil, industrial solar photovoltaic and solar power stations. Among them, the section steel are factory production, uniform specifications, stable performance, excellent corrosion resistance, beautiful appearance. It is worth mentioning that the composite steel bracket system, its on-site installation, only need to use specially designed connectors to assemble the channel steel, the construction speed is fast, no welding is required, thus ensuring the integrity of the anti-corrosion layer. The disadvantage of this product is that the connector process is complex, there are many kinds, and the production and design requirements are high, so the price is not cheap.
