Abstract: A shelf support beam (80, 130, 200) for use in a shelving unit (10) to support a shelf (22). A structural member (82, 132, 202) has a C-shaped cross-section. A web (94, 144, 216) separates a top flange (96, 146, 220) from a bottom flange (112, 162, 234). The top flange (96, 146, 220) is configured to support the shelf (22). The web (94, 144, 216), the top flange (96, 146, 220), and the bottom flange (112, 162, 234) define a channel (92, 142, 214) of the member (82, 132, 202). The channel (92, 142, 214) defines a cavity height (C1, D1, E1). The top flange (96, 146, 220) and the bottom flange (112, 162, 234) define a top flange width (C2, D2, E2) and a bottom flange width (C3, D3, E3), respectively. A ratio of the cavity height (C1, D1, E1) to a sum of the top flange width (C2, D2, E2) and the bottom flange width (C3, D3, E3) is greater than 1, is at least 1.20, or is about 1.40. The C-shaped cross-section has a moment of inertia (98, 148, 238) of greater than 0.40, greater than 0.45, or at least 0.46.

Abstract: A post coupler has one or more positive post stops therein limiting extension of an end of a post section in or over the coupler beyond the stop. The stops may be freely extended tabs or stop embossments from or in the coupler flanges. Outside wrap, inside wrap and hidden post couplers are disclosed, as well as assembly methods.

Abstract: A shelf support beam (130) for use in a shelving unit (10) to support a shelf (22). A structural member (132) has a C-shaped cross-section. A web (144) separates a top flange (146) from a bottom flange (162). The top flange (146) is configured to support the shelf (22). The web (144), the top flange (146), and the bottom flange (162) define a channel (142). The channel (142) defines a cavity height (D1). The top flange (146) and the bottom flange (162) define a top flange width (D2) and a bottom flange width (D3), respectively. A ratio of the cavity height (D1) to a sum of the top flange width (D2) and the bottom flange width (D3) is greater than 1.707 or greater than 1.8. The cross-section has a moment of inertia of greater than 0.0613 or at least 0.0617. The web (144) includes a recessed region (164) in which the structural member (132) is offset in a direction into the channel (142). A centroid (148) of the cross-section is within 0.125 inch of the recessed region (164).

Abstract: A shelving unit includes front and rear shelf supporting beams, each beam including an upper shelf supporting flange that defines a shelf seat and a lower flange spaced from the upper flange, a shelf configured to be positioned in the seat defined by the front and rear shelf support beams, and at least one tie clip configured to be connected to the shelving unit between the shelf and the lower flange of at least one of the front and rear shelf supporting beams. A method of assembling a shelving unit is also disclosed.

Abstract: A post coupler has one or more positive post stops therein limiting extension of an end of a post section in or over the coupler beyond the stop. The stops may be freely extended tabs or stop embossments from or in the coupler flanges. Outside wrap, inside wrap and hidden post couplers are disclosed, as well as assembly methods.

Abstract: A tie bar for connecting two horizontal beams includes first and second elongate walls arranged parallel to each other, and a third elongate wall arranged perpendicular to the first and second elongate walls and coupled to a lateral side of each of the first and second elongate walls. The tie bar further includes at least one pair of hook elements positioned at terminal ends of at least one of the first, second, or third elongate walls. Each of the hook elements includes a depending tab configured to be received by an elongate slot of a horizontal beam of a shelving unit. The first and second elongate walls may be top and bottom walls, respectively, the third elongate wall may be a side wall, and the at least one pair of hook elements may include first and second hook elements positioned on the second elongate wall.
