The photovoltaic bracket forming machine is a specialized cold bending forming equipment for photovoltaic power station supporting profiles. It mainly processes galvanized steel and zinc aluminum magnesium sheet into photovoltaic bracket purlins and connectors such as C-shaped steel, Z-shaped steel, U-shaped steel, etc. It integrates the fully automated process of feeding, leveling, punching, forming, and cutting, and produces profiles with high strength and precise size. It is widely used in various photovoltaic engineering projects such as ground photovoltaic, roof photovoltaic, agricultural photovoltaic complementary, and fishery photovoltaic complementary.
