Photovoltaic power generation as a green power energy development project has been strongly supported by the government in many countries, then we will take a look at what are the commonly used materials of photovoltaic brackets today.
Aluminum alloy photovoltaic bracket:
Aluminum can automatically form a protective film in the air, and the later use does not require anti-corrosion maintenance. Aluminum alloy has the characteristics of light weight, low density, high strength, and is not easy to corrode, and can be reused. However, the bearing capacity of aluminum alloy is low and the price is high, about three times the price of steel, so aluminum alloy brackets are generally used for distributed photovoltaic projects on the roof of buildings with load-bearing requirements.
Galvanized steel photovoltaic bracket:
Zinc steel photovoltaic bracket, generally using Q235 steel as the main material, this material has a high mechanical degree, corrosion protection is generally adopted by heat penetration galvanized treatment measures, later use requires anti-corrosion maintenance. The galvanized steel photovoltaic bracket has stable performance, mature manufacturing process and high bearing capacity, so it is mainly used in power stations with strength requirements, such as large ground power stations, etc., galvanized steel photovoltaic bracket is currently the most common solar photovoltaic bracket.
Flexible photovoltaic bracket:
The flexible photovoltaic bracket is a prestressed structure of steel cables, and the photovoltaic bracket material is mainly one or more combinations of steel strand, steel rope, steel cable, steel cable or steel chain. Its corrosion protection generally adopts hot dip galvanizing treatment measures, the thickness of the galvanizing layer is not less than 65um, and the later use requires anti-corrosion maintenance. The photovoltaic bracket system can save project costs, flexible photovoltaic bracket is suitable for sewage treatment plants, mountainous terrain complex, low bearing roof, forest and light complementary, water and light complementary span and height limit caused by the traditional photovoltaic bracket structure can not be installed in the area. Flexible photovoltaic support has a wide range of applicability, flexible use, saving project costs, and can realize the secondary use of land, and has broad development prospects in the future.
