Double Deep Pallet Racking System
Maximize warehouse storage density by up to 40% over selective racking — without sacrificing forklift accessibility. Gieantech's double deep pallet racking stores two pallets deep per bay, eliminating unnecessary aisles while maintaining efficient FILO inventory flow.
What Is Double Deep Pallet Racking?
Double Deep Pallet Racking is a high-density storage solution that places one row of pallet racking behind another. By storing two pallets deep, it significantly reduces the number of access aisles required, increasing floor space utilization by approximately 40% compared to standard selective systems.
This system operates on the First-In Last-Out (FILO) principle for each pair of pallets. It requires specialized deep-reach forklifts equipped with telescopic forks or a pantograph mechanism to access the rear pallets. Built from high-grade Q235B steel, our racking supports loads up to 4,000kg per level and has been trusted by clients in over 57 countries.

Key Features
Why Choose Double Deep Racking?
40% More Storage
Store two pallets deep per bay, eliminating up to 50% of aisles and increasing pallet positions by 40% in the same warehouse footprint.
Heavy Load Capacity
Engineered for up to 4,000 kg per beam level with Q235B steel uprights and heavy-gauge box beams — ideal for full pallet loads.
Deep-Reach Forklift
Compatible with standard deep-reach trucks that extend to the second pallet position, maintaining efficient retrieval without entering the rack.
Lower Cost per Pallet
Reduce overall racking investment by requiring fewer uprights, beams, and aisle space per stored pallet compared to selective systems.
Easy Selective Upgrade
Uses the same frame and beam components as selective racking — easily convert between selective and double deep configurations as needs change.
Seismic & Safety Design
Cross-bracing, anchor bolts, column protectors, and optional seismic clips ensure structural stability in high-traffic warehouse environments.
Adjustable Beam Levels
Beam heights adjust in 50mm or 75mm increments, accommodating varying pallet sizes and maximizing vertical storage per bay.
Low Maintenance
Simple bolt-together construction with no moving parts — minimal maintenance required. Powder-coated finish resists rust and impact damage.
System Configurations
Double Deep Racking Layouts
Choose from four proven configurations — each optimized for different warehouse layouts, forklift types, and throughput requirements.
Standard Double Deep
Most Popular Configuration
Two rows of selective racking placed back-to-back, accessed from one aisle. The deep-reach forklift handles both front and rear pallet positions. FILO inventory flow — ideal for high-volume, fewer-SKU warehouses.
Double Deep with Pushback
Gravity-Assisted Retrieval
Inclined cart tracks allow pallets to roll forward automatically when the front pallet is removed. Combines double deep density with faster retrieval times — no need for deep-reach truck for rear pallets.
Double Deep Narrow Aisle
Maximum Space Optimization
Paired with articulated or turret trucks operating in aisles as narrow as 1.6m. Achieves the highest storage density possible while retaining pallet-level access — perfect for high-ceiling facilities.
Cold Storage Double Deep
Temperature-Controlled Environments
Engineered for -30°C to +5°C cold chain warehouses with galvanized or epoxy-coated finishes. Reduces refrigerated floor space requirements by 40%, cutting energy costs significantly.
Structural Components
System Component Breakdown
Upright Frames
Heavy-duty Q235B steel uprights with roll-formed C-section profiles. Available in depths up to 1,200mm to accommodate two pallets deep with proper clearance.
Box Beams / Step Beams
Heavy-gauge steel box beams with teardrop or bolt-clip connectors. Load capacity up to 4,000 kg per pair. Step beams available for wire deck or panel support.
Horizontal & Diagonal Bracing
Welded diagonal and horizontal braces within upright frames provide lateral rigidity and structural stability under full load and seismic conditions.
Column Protectors
Bolt-down steel column guards at aisle-facing positions absorb forklift impact, protecting upright frames from damage and maintaining structural integrity.
Wire Mesh Decking
Galvanized welded wire mesh panels placed on beams for pallet support. Improves fire sprinkler penetration, adds fall-through protection, and accommodates irregular pallet sizes.
Safety Pins & Row Spacers
Locking safety pins prevent accidental beam dislodgement. Row spacers maintain consistent spacing between back-to-back uprights for structural alignment.

FAQ
Frequently Asked Questions
Double deep pallet racking places two rows of selective racking back-to-back, storing pallets two deep per bay. A deep-reach forklift with an extendable mast places and retrieves pallets from both the front and rear positions. This eliminates every other aisle, increasing storage density by approximately 40% compared to standard selective racking.
You need a deep-reach forklift (also called a double-deep reach truck) with an extendable pantograph or scissor-reach mechanism. These trucks can extend their forks to access the second pallet position behind the front pallet. Standard counterbalance forklifts cannot reach the rear position. We can recommend compatible forklift models during the design phase.
Double deep provides approximately 40% more storage in the same footprint by eliminating half the aisles. The trade-off is reduced selectivity — only the front pallet in each bay is directly accessible. Selective racking gives 100% pallet access but uses more floor space. Double deep is ideal when you have multiple pallets of the same SKU and don't need instant access to every individual pallet.
Yes, double deep racking is excellent for cold storage (-30°C to +5°C). The 40% increase in pallet positions means you store more product in expensive refrigerated space, reducing energy costs per pallet. We use galvanized or epoxy-coated finishes for cold environments and can engineer the system for condensation resistance.
Our double deep racking supports up to 4,000 kg per beam level (per pair of beams). The exact capacity depends on beam span, upright gauge, and pallet configuration. Each system is engineered with a 1.5–2.0× safety factor to ensure structural integrity under full load conditions.
Absolutely — and we strongly recommend it. A hybrid layout uses double deep rows for high-volume, uniform SKUs and selective rows for fast-moving or diverse products requiring 100% access. Our engineers design optimized hybrid layouts that maximize both density and selectivity based on your specific inventory profile.
Our standard MOQ is 50 bays (negotiable for repeat customers or larger projects). Lead time is typically 15–25 working days from design approval. Shipping time varies by destination — usually 15–35 days for ocean freight. We provide a detailed production schedule and tracking updates throughout the process.
Yes. Double deep and selective racking use the same upright frames and beam components. If your storage needs change, you can simply separate the back-to-back rows and add aisles to create a fully selective layout. This modularity is one of the key advantages of the double deep system over drive-in or push-back alternatives.
Standard finish is electrostatic powder coating (60–80μm thickness) in Blue + Orange or custom RAL colors. For corrosive or cold storage environments, we offer hot-dip galvanizing (80–120μm) or epoxy coating. All finishes pass 500+ hour salt spray testing for long-term corrosion resistance.
