What is a Pallet Rack System?
Pallet rack systems are material handling solutions used in warehouse and distribution centers to store pallets of goods. In their most common application, pallet rack systems consist of two uprights that are held connected by a set cross beam members. Multiple levels can be achieved using additional cross beams. In defining a pallet rack system one has to know the height, weight, and depth of the pallets being stored as well as the area size and ceiling height of the location,
In areas that are susceptible to seismic activity, a heavy duty baseplate is welded to the bottom ends and this is bolted to the concrete floor.
Strength and weight capacities are determined using the composition of the metal used for fabrication combined with the width and type of uprights and beams used. Ideally, engineering calculations should be performed during the design phase.

Here, two uprights and four beams are used to create a three-level storage system.
