When considering pallet rack systems the two main components are the upright frame and beam. The upright frame of all pallet rack systems is the main structure that stands in a vertical position, while the horizontal beam determines the size of the bay and holds the load.

We believe that it is important to select industry standard style pallet rack systems.
