What Is a Pallet Rack?
Pallet racks are industrial storage systems designed for stacking palletized materials in horizontal rows with multiple levels. They are essential for maximizing warehouse space, improving inventory access, and enhancing operational efficiency for virtually every industry that handles bulk storage.
Types of Pallet Racks
The right racking system depends on your space, inventory turnover, and picking method. Here are the most popular options:
Selective Pallet Rack
The standard choice for most warehouses—offers direct access to every pallet, flexible layouts, and easy adjustability. Best for high SKU count and fast picking.
Drive-In / Drive-Through
Maximizes storage density by reducing aisles. Forklifts drive into lanes. Ideal for LIFO/FIFO storage and large quantities of similar products.
Push Back Rack
Multiple pallets deep; uses rolling carts on rails. High density, LIFO system for quick, space-saving access to multiple pallets per SKU.
Pallet Flow Rack
First-in, first-out (FIFO) with gravity rollers—pallets automatically move forward as one is removed. Best for perishables and time-sensitive goods.
Cantilever Rack
For long, awkward, or heavy items (lumber, pipe, furniture). No front column, so items of any length can be stored and retrieved easily.
Double Deep Rack
Stores two pallets deep per row, increasing storage density while maintaining selectivity. Requires a deep-reach forklift for access.
How to Choose the Right Rack for Your Needs
Consider these five steps for the best decision:
1. Assess Load & Inventory
Understand what you store—pallet size, weight, SKU variety, turnover rate, and product sensitivity. Heavier or non-standard items may require specialized racks.
2. Measure Warehouse Space
Record clear height, column placement, and aisle width. Plan for forklift movement and ensure compliance with fire and safety codes.
3. Choose Rack Type
Match rack design to your storage goals: Selective for access, drive-in for density, push back for fast LIFO, pallet flow for FIFO, or cantilever for long items.
4. Consider Future Expansion
Opt for modular systems or layouts that allow for easy additions or reconfigurations as your business evolves.
5. Prioritize Safety
Always use safety accessories: row spacers, column protectors, rack guards, and wire decks. Verify that racking is engineered for your local code and seismic zone.
Key Benefits of a Properly-Designed Pallet Rack System
- Maximizes vertical and horizontal warehouse space for more storage in the same footprint.
- Improves picking speed and reduces errors for streamlined order fulfillment.
- Enhances warehouse safety and protects product from damage with the right accessories.
- Reduces long-term costs by enabling better inventory control and efficient workflows.
- Adaptable to changing business needs, product lines, and expansion plans.
New vs. Used Pallet Racks: Which Is Right?
New pallet racks offer the longest warranties, all safety certifications, and custom dimensions/colors. Used racks save budget and can ship fast—but always buy from a reputable supplier and inspect for structural integrity.
💡 Pro Tip: When buying used, ask for detailed inspection reports and photos. Ensure beam and upright brands are compatible with your layout!
Installation & Safety
- Have racks installed by experienced professionals.
- Confirm all anchors, spacers, and hardware are secure and code-compliant.
- Schedule annual rack inspections for ongoing safety and compliance.
- Train your staff on safe material handling and rack load limits.
