Vehicle bed edge and manufacturing process

摘要

A roll-formed one-piece vehicle bed member having plural downwardly-opening channel-like ribs extending longitudinally of the bed member and terminating at front and rear edges. The ribs adjacent one end are deformed to define rib portions which slope downwardly from the top of the ribs for merger with a flat transverse edge flange. The top wall of the sloped rib portion has a center wall portion which is offset downwardly relative to side edge portions which join the center wall portion to side walls of the rib.
