Abstract:
A dunnage bar system that includes an bar with a generally rectangular cross section. In one embodiment, the bar has four external faces that are joined by arcuate corners . The four faces include an impact-absorbing face that has two arms of a C-section ; a basal face opposing the impact-absorbing face ; and a pair of side faces that are oriented between the impact-absorbing and basal faces and . Preferably, a pair of channels extend at least partially along and within the bar . Each channel has a pair of opposing internal major walls ′ and opposing internal minor walls ′. In alternative embodiments, one or more spacer members ′ are insertable into the channels 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.
