description The invention discloses high-precision hot-rolled U-shaped steel, and belongs to the technical field of hot-rolled U-shaped steel. The high-precision hot-rolled U-shaped steel is formed by rolling heated steel at the temperature higher than the recrystallization temperature and specifically comprises a bottom plate and leg edges, and the leg edges are fixedly arranged on the two sides of the bottom plate; grooves are formed in the top ends of the leg edges on the two sides through planing and milling, and truncated edges are reserved on the sides, not provided with the grooves, of the leg edges in the thickness direction. The U-shaped steel manufactured through the method has the advantages of being high in manufacturing precision, standard in specification, small in error size, easy to achieve small deformation, tight in connection and the like. The cutting procedure in a steel structure processing factory is reduced, the material loss is reduced, the processing material and labor input cost is reduced, and
