Background

Conventional rims for photovoltaic modules are made of aluminum materials, and are light, but have limited strength, but the demands of the current market for the modules capable of bearing high loads are increasing, so that stronger steel rims are becoming popular in the market. However, the aluminum frame is processed and molded by adopting a stamping process, a more complex bearing structure can be formed to improve the bearing capacity of the frame, and the steel frame material can be processed only by adopting a bending process, so that the more complex bearing structure cannot be formed, and the improvement of the structural strength of the steel frame material is limited to a certain extent.
