Photovoltaic bracket material selection

Aluminum alloy: Aluminum alloy brackets are corrosion-resistant, lightweight, beautiful and durable, and are generally used in building rooftop photovoltaics. The cost of aluminum alloys is relatively high, but its advantages make it very popular for specific applications.
Hot-dip galvanized steel (hot-dip galvanized steel): Hot-dip galvanized steel brackets have stable performance, mature manufacturing technology, high bearing capacity and easy installation. This kind of bracket is widely used in civil and industrial solar photovoltaic power plants.

Zinc-aluminum-magnesium: The cross-section of the photovoltaic bracket made of zinc-aluminum-magnesium can still maintain good corrosion resistance even after it is cut and installed on site. This is because its cutting surface can automatically generate a dense protective film to prevent further corrosion of the photovoltaic bracket.
Resin-based composite materials: This material has the characteristics of light weight, high strength, corrosion resistance, aging resistance, and good electrical insulation. With the deepening of research on composite materials, its application in the field of photovoltaic brackets has become more and more extensive.

In addition to the above materials, other metal materials such as stainless steel can also be used to manufacture photovoltaic brackets. When selecting photovoltaic brackets, factors such as weather resistance, structural solidity, installation cost, maintenance cost, and service life need to be considered. At the same time, the appropriate bracket type and material should be selected based on the geographical, climatic and solar resource conditions of the construction site to ensure the maximum power output and stable operation of the entire photovoltaic power generation system.
