Abstract: An installation shelf arrangement or like storage arrangement comprising cantilever arms projecting substantially horizontally from substantially vertical uprights, in particular for the storage of long material, wherein the cantilever arms are each connected to the respective upright by a bolt-like member which passes through openings in the cantilever arm and apertures in the upright is to be simplified and made suitable for use for higher loads. For that purpose the upright (14) which carries the cantilever arms (16) has two channel-like profiles (24) which face towards each other with their open sides, and at least one transverse member (26, 27) which connects the profiles at a spacing (a) and which is fixed at both ends to a pair of substantially aligned profile limbs (38).
