Processes for roll forming a bed assembly for a pickup truck including horizontally floor panel and right and left upright inner side panels

摘要

A vehicle box assembly wherein a bed floor and the inner right and left side wall panels are defined by and assembled from two monolithic one-piece integrated side/floor panel members. The two panel members are preferably formed by roll forming a thin metal sheet so that only a single roll-formed panel configuration is required. Subsequent forming operations, such as punching or die forming, are carried out on the roll-formed configuration to create right and left panel members which are assembled to define the floor and opposed inner side panels of the box assembly.
