Corner pieces in aluminum alloy profile accessories are commonly used connectors in industrial aluminum alloy profile accessories, generally used for vertical or cross connections of industrial aluminum materials. Commonly used corner pieces are used to strengthen the support force of the connected profile points, and can also be used as a connection method for profiles that need to be moved; Strong corner pieces are commonly used for supporting and fixing profiles and profile points that are subjected to strong forces or vibrations; Steering angle pieces are used for connecting intersecting profiles.

Aluminum alloy profiles also play an important role in the transportation field, mainly used in the manufacturing of railway vehicles, automobiles, airplanes, ships, etc. Its advantages include low density, high strength, and good rigidity, which can improve the load-bearing capacity and operational efficiency of transportation vehicles.
