A conveyor system that can readily transport I-beams, angle irons, T-beams, channel members, and like components without any modifications to the system being necessary. The system includes a plurality of sets of roller pairs, each roller being contoured so that it has various surfaces that will accept components and properly engage them for transport. Each pair of rollers is mounted for rotation about a common axis, and a power actuated structure is provided for adjusting the spacing between the rollers of each pair to accommodate components of different sizes.
