A storage rack beam includes top and bottom flanges and at least one web that interconnects the flanges. The web includes at least one stiffening formation arranged to stiffen an intermediate region of the web along at least a substantial portion of its length so as to resist lateral loading applied to the beam. The racking beam may take various forms, including first and second U-shaped sections in opposed abutting relationship, or formed as a closed S-shaped profile. Also disclosed is a storage rack beam that has a vertical loading capacity and a horizontal loading capacity, wherein at least part of the horizontal loading capacity is independent of the vertical loading capacity applied to the beam.
A racking beam having vertical loading as its primary loading condition and comprising top and bottom flanges, at least one web interconnecting the flanges, and at least one stiffening formation arranged to stiffen an intermediate region of the at least one web along at least a substantial portion of its length such that the at least one stiffening formation enables the racking beam to provide resistance to lateral impact loading at any level of primary loading up to the full vertical loading capacity of the beam.
A racking beam that has a vertical loading capacity as its primary loading condition and a horizontal loading capacity, wherein at least part of the horizontal loading capacity is independent of the level of vertical loading applied to the beam so that the racking beam can still provide resistance to horizontal impact loading whilst the beam is supporting its full vertical load.
The racking beam according to claim, wherein the racking beam comprises top and bottom flanges, at least one web interconnecting the flanges, and at least one stiffening formation operative to stiffen an intermediate region of the at least one web along at least a substantial portion of its length.
The racking beam according to claim, wherein the first and second members are U sections, each section having a flange, first and second webs projecting from the flange, inwardly extending lips at the distal end of the respective webs, and a lip return disposed at a distal end of the lips, and wherein the two U sections are in opposed abutting relationship with the flanges of the sections forming respectively the top and bottom flanges of the racking beam, and respective ones of the webs of the sections being aligned so as to form the first and second webs of the beam.
