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).

         7 . The shelf support beam of  claim 1  wherein the C-shaped cross-section has a centroid and the centroid is within 0.125 inch (0.3175 centimeter) of the web. 
     
     
         8 . The shelf support beam of  claim 1  wherein the web includes a recessed region in which the structural member is offset in a direction into the channel. 
     
     
         9 . The shelf support beam of  claim 8  wherein the C-shaped cross-section has a centroid and the centroid is within 0.125 inch (0.3175 centimeter) of the recessed region. 
     
     
         10 . The shelf support beam of  claim 8  wherein the recessed region is at least 30% of an overall height of the structural member. 
     
     
         11 . The shelf support beam of  claim 8  wherein the recessed region is in a range of 30% to 70% of an overall height of the structural member. 
     
     
         12 . The shelf support beam of  claim 8  wherein the recessed region is about 70% of an overall height of the structural member. 
     
     
         13 . The shelf support beam of  claim 1  wherein the C-shaped cross-section has a gauge of 0.054 inch (0.1372 centimeter). 
     
     
         14 . The shelf support beam of  claim 1  wherein the C-shaped cross-section has a strip width of 3.656 inches (9.286 centimeters).
