This is the only van rack completely fabricated first and then hot dip galvanized for a rust free abrasive resistant finish on every cut end, weld and inch of the rack. And this rack doesn’t end with the finish. Each rack includes completely welded side trusses made from 11?4" and 3?4" 14 ga steel tubing and solid 1?4" steel rod. Cross supports are 11?4" 13 ga round tube.
