Square tubes are the core structural components of the solar support system. They are made of rigid steel with a square cross section. They have the characteristics of high strength, light weight and weather resistance. They are designed to carry photovoltaic panels and withstand extreme environments. As the “skeleton” of the photovoltaic array, its performance directly affects the safety, stability and life of the power station, and is the basic guarantee for the efficient operation of the photovoltaic system. They are mainly used in large ground power stations, distributed rooftops, and agricultural and fishery photovoltaic complementarity.
