In rigid structure buildings, a variety of steel components are needed, the most common of which are steel pipes and H-shaped steels. H-shaped steels can be used as beams and columns in steel structure buildings. After production, H-shaped steels need to be stacked together. After being placed for a long time, a layer of rust will form on the surface of the H-shaped steels, which need to be polished and rusted. However, due to the special structure of the H-shaped steels, conventional polishing structures cannot be used to polish the entire surface. Patent application number CN202020650394.6 discloses an H-shaped steel surface polishing device, including a mounting frame, mounting blocks are provided on both sides of the bottom end of the mounting frame, and a mounting groove is provided on the upper end of the mounting block.
