Pallet rack is used for industrial strength warehouse shelving storage. Pallet rack commonly come in one of two configurations: a roll formed, or clip-in configuration, and a structural bolt-together configuration.
Roll Formed Pallet Rack – Roll formed selective rack is most commonly manufactured in a “teardrop” style. The nickname “teardrop” comes from the fact that the holes on the column of the upright are shaped like a teardrop. Pallets then rest on the horizontal load beams that are held in place by mounting clips. Because the clips on teardrop configurations can be quickly moved, the shelves can be easily adjusted to different heights to accommodate various load sizes. This is convenient for a warehouse that needs to store a wide variety of product sizes.
- Roll formed racks are less expensive
- Roll formed rack beams are held in place by mounting clips and be more easily moved than structural beams which are bolted in place
Structural Pallet Rack – Structural pallet rack systems are very similar to roll formed pallet rack systems except the horizontal load beams are attached to the uprights with bolts and have much greater weight-bearing capacity. Also, structural pallet racking can be designed into the structure of the building itself, so that the upright columns are simultaneously used to support the roof of the storage facility, in which case the structural pallet rack uprights replace the storage building’s vertical support I-beams. This system is a rack supported building.
- Structural rack is heavier and less prone to forklift damage
- It is necessary to use structural racks in certain applications because it can handle heavier pallet loads
