A cantilever shelving system is disclosed and can include a frame structure, a cantilever shelf support structure, and a plurality of load-bearing shelves that can be supported by the cantilever shelf support structure and the frame structure. The shelves can be positioned laterally adjacent to cantilever support arms of the cantilever shelf support structure, and the shelf support surfaces can be coplanar with upper walls of the cantilever support arms. Ends of laterally adjacent shelves do not overlap with a front side of a vertical support member to which the cantilever support arm is mounted. The cantilever shelving system can accommodate various user requirements and can be operably integrated with standard commercial and/or industrial equipment or machinery.
