Choosing the right pallet rack system is one of the most impactful decisions you’ll make for your warehouse. The wrong choice wastes space, slows operations, and can even create safety hazards. The right system maximizes every cubic foot while keeping your team efficient and safe.

In this guide, we’ll walk through every major pallet rack type, compare costs and capacities, and help you decide which system fits your operation. Whether you’re outfitting a new facility or upgrading an existing one, this is the resource you need.

What Is a Pallet Rack System?

A pallet rack system is a material handling storage structure designed to store palletized goods in horizontal rows with multiple levels. These systems use vertical space that would otherwise be wasted, transforming a single-story warehouse into a multi-level storage operation.

Modern pallet racks are engineered to specific load capacities and seismic requirements, making them far more than simple shelves. They’re structural systems that must be designed, installed, and inspected to ANSI/RMI standards.

Types of Pallet Rack Systems

Selective Pallet Rack

Best for: Warehouses that need direct access to every pallet position.

Selective rack is the most common system in North America, accounting for roughly 85% of all installations. Each pallet sits on a pair of beams and can be accessed directly by a forklift without moving other pallets.

• Pros: 100% selectivity, lowest cost per bay, easy to reconfigure
• Cons: Requires an aisle for every row, lower density than other systems
• Typical cost: $50–$120 per pallet position (new)
• Load capacity: 2,000–10,000 lbs per beam pair

Drive-In / Drive-Through Rack

Best for: High-density storage of identical SKUs with LIFO (last-in, first-out) inventory flow.

Drive-in racks eliminate aisles between rows, allowing forklifts to drive directly into the rack structure to store and retrieve pallets. This can increase storage density by 75% compared to selective rack.

• Pros: Maximum density, ideal for cold storage and bulk operations
• Cons: Limited selectivity (LIFO), slower throughput, higher damage risk
• Typical cost: $100–$200 per pallet position
• Best depth: 5–10 pallets deep

Push-Back Rack

Best for: Medium-density storage with LIFO flow and faster throughput than drive-in.

Push-back rack uses nested carts on inclined rails. When you load a pallet, it pushes the previous pallets back. When you remove one, the remaining pallets roll forward by gravity.

• Pros: Higher density than selective, faster cycle times than drive-in
• Cons: LIFO only, 2–6 pallets deep, higher cost per position
• Typical cost: $150–$350 per pallet position

Pallet Flow (Gravity Flow) Rack

Best for: FIFO (first-in, first-out) inventory management, perishables, and high-volume distribution.

Pallets are loaded at the back and flow forward on roller conveyors to the pick face. This guarantees product rotation and is popular in food, beverage, and pharmaceutical warehouses.

• Pros: FIFO rotation, high density, automatic replenishment
• Cons: Highest cost per position, requires maintenance of rollers and brakes
• Typical cost: $200–$500 per pallet position

Cantilever Rack

Best for: Long, bulky, or irregularly shaped items — lumber, pipe, tubing, furniture, and sheet goods.

Cantilever rack uses arms that extend from vertical columns, with no front uprights to block loading. This makes it the only practical solution for storing items that are too long for standard pallet rack. Learn more about our Cogan cantilever rack systems →

• Pros: Stores any length, easy front-loading, adjustable arm heights
• Cons: Lower density, not designed for pallets, higher cost per linear foot
• Typical cost: $200–$600 per storage arm

How to Choose the Right Pallet Rack System

Selecting the right system depends on several factors:

1. SKU count: More SKUs → selective rack. Fewer, high-volume SKUs → drive-in or push-back.
2. Inventory rotation: FIFO required? → Pallet flow. LIFO acceptable? → Push-back or drive-in.
3. Throughput requirements: High picks per hour? → Selective or push-back. Bulk storage? → Drive-in.
4. Available space: Limited floor space? → High-density systems. Tall ceilings? → Add beam levels.
5. Budget: Selective is most affordable. High-density systems cost more but reduce required square footage.

Pallet Rack Cost Breakdown

System Type	Cost per Position	Density Gain	Selectivity
Selective	$50–$120	Baseline	100%
Double-Deep	$80–$150	+30%	50%
Drive-In	$100–$200	+75%	Low
Push-Back	$150–$350	+50%	Last pallet only
Pallet Flow	$200–$500	+60%	Front pallet only
Cantilever	$200–$600/arm	N/A	100%

Costs are approximate for new equipment and vary by height, depth, and load rating.

Installation Best Practices

Proper pallet rack installation is critical for safety and performance:

• Anchor every column: All uprights must be anchored to the concrete floor per RMI guidelines.
• Use a plumb line: Racks must be plumb and level to prevent uneven loading.
• Install column protectors: Especially on aisle-facing columns to prevent forklift damage.
• Add safety accessories: Row spacers, pallet supports, netting, and load capacity signs.
• Get a permit: Many jurisdictions require building permits for rack installations over a certain height.

Frequently Asked Questions

How much weight can pallet rack hold?

Standard selective rack holds 2,000–10,000 lbs per beam pair, depending on beam size, length, and connection type. Upright frames are typically rated at 20,000–30,000 lbs per column. Always check your rack’s specific load placard.

How long does pallet rack take to ship?

New pallet rack from domestic manufacturers ships in 4–8 weeks. In-stock and used rack can ship within days. Read our pallet racking lead times guide for current timelines.

Can I mix pallet rack brands?

No — beams and uprights must be from the same manufacturer. Teardrop connections vary between brands and are not interchangeable, even if they look similar.

Do I need a permit for pallet rack?

In most jurisdictions, installations over 8 feet require a building permit and may require engineered drawings signed by a PE. Your rack dealer should handle permitting.
