Abstract: A cargo carrier includes a plurality of laterally extending and longitudinally spaced-apart cross members, a plurality of longitudinally extending decking extrusions supported on the cross members and forming a cargo deck, and retainers securing the decking extrusions to the cross members. The retainers limit or substantially prevent vertical relative movement between the decking extrusions and the cross members. The retainers permit longitudinal relative movement between the decking extrusions and the cross members and at least one end of the decking extrusions is provided with a gap so that the decking extrusions can move in the longitudinal direction to reduce shear stress at the decking connections due to deflection of the decking extrusions, thermal expansion and contraction of the decking extrusions, and the like.
