A storage system includes a shelf bracket that has an elongate rigid mounting structure. The shelf bracket includes a top arm extending outwardly from, and orthogonal to, the elongate rigid mounting structure. The shelf bracket further includes a bottom arm extending outwardly from the elongate rigid mounting structure, at an angle of between 5-60 degrees. The bottom arm is in the form of a strut channel that includes a U-shaped cross section that includes a back wall, two opposed side walls extending downwardly from the back wall, each of the opposed side walls extending to an inwardly extending portion, which extends to an edge.
