Abstract
A section steel straightener for correcting deformations in section steel, such as H-beams. The straightener allows for adjusting the width of the rollers without disassembling the apparatus, but rather by rotating sleeves to change the distance between rollers. Also disclosed is a plurality of rollers forming at least one of the fixed roller and movable roller such that the required amount of movement of the movable roller is reduced, thereby reducing idle time of the straightener.
