A pallet rack system is a steel structure in which inventory is stacked in multiple levels. Pallet racks are typically built for optimum density of storage and designed for easy access to inventory, reconfigurable use, and simple assembly.
Let’s review some of the structural aspects of the typical pallet rack system. The so-called “step beams” (a.k.a. “cross beams” or “load bars”) connect horizontally to upright frames, forming a grid architecture that allows for all manner of storage possibilities. The frames (or “uprights”) are punched with holes to allow connection of the step beams. Most pallet rack systems also utilize an array of accessories such as spacers, ties, wire mesh decks, and braces to stabilize the structure. A wire mesh deck, for instance, may be installed to provide storage flexibility and additional support for inventory. Of course, every customized pallet rack system is slightly different, from an engineering point of view, so it’s important to speak with your vendor to install the best accessories for your particular system and warehouse configuration.
Pallet rack systems can be designed for a plethora of uses. Some pallet rack systems are built for inventory that needs to be rotated and accessed quickly. Other rack systems emphasize weight bearing capacity. Still others boast easy installation, low cost materials, and reconfigurable storage design. Finally, if you have limited space in your warehouse, you can select pallet racks based on their density capacity.
Pallet rack systems can present safety hazards if they’re not constructed and maintained properly. Obviously, if a structure is overloaded, it can warp or even collapse. Broken, missing, mismatched components, and damaged bracing or footplates can also lead to structural compromise. Your vendor should alert you to potential weak spots, but it’s often the warehouse owner’s legal responsibility to inspect the system and ensure the safety of workers and visitors. Remember - poor ventilation or overly tight packing of pallets can present fire hazards.
When assessing various pallet rack systems, factor in the cost of assembly, the cost of any required permits, inspections and taxes, and the costs of freighting the steel components of your pallet rack system. (If you find a terrific deal on warehouse quality steel but then have to ship it hundreds of miles to your warehouse, your final price tag may be less than ideal.)
Although pallet rack systems may seem like out of the box solutions to warehouse storage problems, they need to be designed by a qualified, experienced person that can customize and enhance the equipment to fit your unique commercial needs. Articulate your storage and inventory rotation needs in as much specificity as possible before shopping for your pallet rack system and you’ll find it much easier to select the perfect structure and design for your business needs.
