This utility model discloses a rotary coating fixture for metal materials, relating to the field of metal material coating processing technology. It includes a base assembly and clamping components. A base assembly is movably connected to the top of the base assembly, and a rotating component is movably mounted on the top of the base assembly. A stabilizing platform assembly is mounted on the top of the rotating component. The clamping components are horizontally mounted on the top surface of the stabilizing platform assembly. This rotary coating fixture for metal materials, by horizontally circling four sets of clamping components on the surface of the stabilizing platform assembly, allows for flexible and stable clamping of the metal material being processed by adjusting the structure of each set of clamping components. This provides good stability and support without affecting the processing of the metal material. Furthermore, the structural combination of the base assembly, connecting platform, and rotating components allows for both axial rotation in the vertical direction and vertical folding adjustment of the stabilizing platform assembly.
