Explore our heavy-duty industrial rack portfolio optimized for dense vertical footprints, deep-reach forklift operations, and regional seismic compliance.
In industrial hubs across the Kansai region—spanning Osaka Nanko Port, Sakai-Senboku coastal industrial zone, Higashiosaka precision clusters, and Ibaraki logistics parks—real estate footprints carry significant land lease premiums. Traditional single-selective pallet racking systems dedicate up to 60% of floor space entirely to forklift movement aisles, creating a severe operational bottleneck in high-density zones.
The Double Deep Pallet Racking System resolves this footprint challenge by positioning pallet configurations two rows deep instead of one, eliminating one access corridor for every pair of double racks. This layout converts floor space into storage volume, increasing storage density by 30% to 40% compared to standard selective setups while requiring significantly lower capital investment than fully automated robotic crane retrieval systems.
| System Feature | Standard Selective Racking | Double Deep Racking | Drive-In Pallet Racks |
|---|---|---|---|
| Aisle-to-Storage Ratio | 60% Aisle / 40% Pallets | 35% Aisle / 65% Pallets | 20% Aisle / 80% Pallets |
| Direct SKU Selectivity | 100% Immediate Direct Access | 50% Immediate (Dual Depth) | < 15% (Strict Tunnel Batching) |
| Required Forklift Fleet | Standard Counterbalance / Reach | Pantograph Reach / Telescopic Forks | Narrow Chassis Drive-In Mast |
| Seismic Damping Adaptability | Moderate Rigidity | Superior Structural Ties | Requires Substantial Top-Tying |
| Ideal SKU Velocity | High Velocity / Highly Diverse | Medium-High Velocity / Homogeneous Batches | Low SKU Diversity / Bulk Static |
Double Deep setups are especially effective for JIS standard pallets (1,100 × 1,100 mm) commonly deployed throughout Japanese maritime imports. By connecting rows with heavy-duty structural spine spacers and oversized welded column base shoes, Double Deep configurations naturally establish a rigid, interconnected spatial frame structure that delivers enhanced resistance against seismic ground displacement.
Custom tailored rack structural engineering addressing high throughput, refrigerated supply, and regional industrial supply chains.
Refrigerated warehouse space carries high utility overheads. Double deep pallet systems in Osaka bay cold-chain facilities deliver ultra-dense pallet footprints for seafood, dairy, and meat trade imports without requiring cold-store rated mobile track power gear.
Local tooling and precision parts assembly hubs demand reliable medium-duty pallet consolidation. We pair double deep configurations with heavy-duty wire mesh decking and drop-in safety pallet support bars to accommodate non-standard steel containers safely.
Fast-Moving Consumer Goods operators handling high-turnover SKUs leverage double deep setups to group fast items in double runs. This operational arrangement boosts reach-truck pick times and keeps seasonal volume spikes within existing floor footprints.
Warehouse logistics in Western Japan are experiencing structural changes driven by land supply constraints, building regulations, and evolving labor dynamics:
Developers are building modern multi-tenant ramp-up distribution hubs throughout coastal Osaka. Due to high ceiling clearances (5.5m - 6.5m clear), companies are replacing low floor racking with tall Double Deep frameworks to capitalize on every available vertical meter.
Located in a region conscious of Nankai Trough earthquake preparedness, installations require verified seismic resilience. Double deep racks gain structural rigidity through matched back-to-back connectors, frame base reinforcement, and dynamic deflection testing.
Truck driver overtime caps under Revised Labor Standards legislation require rapid truck turnaround times at logistics docks. Double deep storage arrangements decrease dock-floor congestion by keeping staging pallets organized in dense, accessible lanes.
With more than two decades of dedicated industrial manufacturing excellence, Guangzhou HEDA Shelves operates a state-of-the-art 30,000-square-meter facility with an experienced engineering team of 300+ professionals.
