Abstract: A one-piece dunnage bar for a dunnage rack of the type used to store and transport parts within an automotive factory. The dunnage bar includes integral inner and outer C-shaped portions roll-formed from a single piece of structural metal. The inner and outer portions each include overlying wall segments that cooperate to define the mouth of the C shape. The thickness of each of these wall segments is one-half of the thickness of the remainder of the walls so that the pancaked wall segments have a combined thickness approximately the same as that of the remaining walls.

Abstract: Specification discloses a dunnage bar for a dunnage rack of the type used to store and transport parts within an automotive factory. The dunnage bar includes an outer C-shaped bar and an inner T-shaped bar both roll-formed from structural metal. The inner bar is closely received within and spot-welded to the outer bar. The stem of the inner bar engages the outer bar opposite the mouth and includes spaced webs permitting a welding fixture to be inserted through the mouth and between the webs. The cross arms of the inner bar also engage the outer bar and include spacer webs at their terminal edges to space the inner bar from the mouth of the outer bar.
