摘要： A dunnage bar system 10 that includes an bar 12 with a generally rectangular cross section. In one embodiment, the bar has four external faces 14, 16, 18, 20 that are joined by arcuate corners 22. The four faces 14, 16, 18, 20 include an impact-absorbing face 14 that has two arms of a C-section 30, 32; a basal face 16 opposing the impact-absorbing face 14; and a pair of side faces 18, 20 that are oriented between the impact-absorbing and basal faces 14 and 16. Preferably, a pair of channels 36 extend at least partially along and within the bar 12. Each channel 36 has a pair of opposing internal major walls 40, 40′ and opposing internal minor walls 44, 44′. In alternative embodiments, one or more spacer members 70, 70′ are insertable into the channels 36 for torsional rigidity and added support. Each wall terminates in an internal corner having a radius. The invention also includes a process for making the disclosed composite bar system.
