The present invention comprises a workpiece container for storing at least one workpiece having a bottom surface and a peripheral edge. In one embodiment, a workpiece support structure is located within the container enclosure, which forms multiple vertically stacked storage shelves within the enclosure. Each storage shelf includes, in one embodiment, a first tine and a second tine for supporting the workpiece in a substantially horizontal orientation. The bottom surface and peripheral edge of a workpiece seated on a storage shelf extends beyond the outer edge of both the first tine and the second tine. An end effector according to the present invention may engage these extended portions or “grip zones” of the workpiece.
