[0002] The steel frame of a photovoltaic module is the external metal frame of the photovoltaic module, mainly used to provide structural support, protection, and enhance the mechanical strength of the module. It is an important part of photovoltaic module manufacturing and is usually made of steel, aluminum alloy, or other metal materials. Steel frames are often chosen due to their durability and strength. The steel frame usually refers to the structure made by passing steel strips through a series of rolling dies, gradually shaping and setting them to form a frame suitable for photovoltaic modules.
