This invention relates to a straightening mill for section steel, such as I-beams, channel steel, etc., particularly to a straightening mill for section steel, wherein as the section steel is straightened so called "end crook" at the tail end thereof is eliminated. The section steel is passed through a straightening mill which comprises a plurality of driving rollers and a plurality of driven rollers defining a pass line therebetween. The axes of the driving and driven rollers are staggered and, except for the first driving roller, each of the driving rollers is fixed relative to the pass line. The driven rollers are adjustable and by proper adjustment of the first driving roller relative to the pass line, end crook is reduced or eliminated.
