Abstract: A shelved storage rack has end frames including end posts and cross-beams therebetween. The beams each comprise a vertical panel having a reverse bend therefrom which results in an outwardly extending horizontal flange adapted to support a deckplate; the vertical panel being longitudinally extended at each end with regard to the flange; and a removable planar connector plate fastened along the longitudinal face of each panel extension. First and second tab means extending from the plate in the beam in a longitudinal direction and overlying, in operative association with, a face of the post. The first tab means terminating in inwardly directed hook means which secure on aperture defining structure in said post face.
