Direct Sourcing Portfolios
Engineered Double Deep & High-Density Pallet Racking Systems
Manufactured in our audited Guangzhou facilities using automated cold-roll forming, multi-stage surface passivation, and heavy structural Q235B/Q355B steel grades.
Direct OEM / ODM Manufacturing Competence
Why Global Supply Chains Source from Guangzhou Heda Shelves
Founded in 2001, Guangzhou Heda Shelves Co., Ltd. controls over 30,000 square meters of modernized production infrastructure, delivering certified warehouse structures across 120+ countries.
Complete Structural Traceability
Every beam, upright column, and brace is cold-formed from high-tensile structural steel coils. We apply full-depth automated punching, robotic MIG welding, and rigorous load-bearing certification conforming to international safety standards.
Direct Factory Cost Efficiency
By eliminating intermediary brokers, international logistics operators gain tier-1 Chinese wholesale factory pricing, fully customizable upright punch profiles (50mm/75mm pitch), and tailored packaging that maximizes container cubing.
Pickling, Phosphating & Anti-Rust
All structural frameworks undergo a multi-stage pretreatment including automated chemical pickling and phosphating before electrostatic polyester powder application. This creates extreme resilience against moisture, thermal cycling, and coastal air.

Double Deep Pallet Racking: Mechanical Principles & Volumetric Efficiency
Balancing direct accessibility and dense footprint utilization: A technical comparison for material handling architects.
In contemporary intralogistics, real estate expenditures dictate maximum cube utilization. Standard selective pallet racking configurations dedicate up to 60% to 65% of warehouse floor footprint exclusively to operational aisles. The Double Deep Pallet Racking System re-engineers this spatial equation by storing pallets two-deep in a back-to-back arrangement, eliminating every alternate aisle and increasing storage density by up to 30% to 40% over standard single-selective layouts.
Structural Comparison: Selective vs. Double Deep vs. Drive-In
| Parameters | Standard Selective | Double Deep System | Drive-In Racking |
|---|---|---|---|
| Floor Area Utilization | 35% – 40% High Aisle Ratio | 55% – 65% Optimized | 65% – 75% Maximum Density |
| Pallet Selectivity | 100% Instant Direct Access | 50% Immediate (FILO Pairing) | 15% – 20% Restricted Access |
| Handling Equipment | Standard Counterbalance / Reach | Pantograph / Telescopic Reach | Narrow-body Counterbalance |
| Throughput Velocity | High Rotation FMCG | Medium-High Homogeneous | Low-Medium Batch Rotation |
| Capital Cost per Position | Lowest Baseline | Extremely Low ROI Delta | Moderate to High Structural Rigidity |
Double Deep systems rely on the FILO (First In, Last Out) principle per individual two-deep lane, while preserving full selective accessibility along the operational face. This structure is suited for manufacturing inventories, cold storage facilities where cubic refrigeration energy must be conserved, and FMCG staging where goods have moderate turnover rates and multiple pallets per identical Stock Keeping Unit (SKU).
Industry Forecast
Future Procurement & Technology Trends in Industrial Racking
How automation, dynamic digital twins, and climate-resilient manufacturing are shifting global racking investments.
Integration with Automated Guided Vehicles (AGVs)
Traditional manual deep-reach forklifts are increasingly supplanted by automated reach trucks and pantograph AGVs. Modern procurement mandates tighter frame tolerances (within ±1.0mm per section), accurate rail-guided entry channels, and embedded optical positioning targets integrated directly into upright beams during factory fabrication.
Carbon Footprint Auditing & Steel Traceability
Western enterprise procurement standards (e.g., ESG requirements) demand full metallurgical traceability from green steel blast furnaces. Forward-looking China manufacturers are deploying low-emission roll-forming technologies and non-toxic powder coating curing systems certified to European RoHS standards.
Structural Health Monitoring via IoT Sensors
Next-generation double-deep and high-bay setups are adopting structural sensors capable of monitoring live dynamic deflection, impact force from material handling equipment, and seismic stress in real-time, feeding maintenance analytics to enterprise WMS software.
Procurement Clarifications
Frequently Asked Questions for Wholesale Racking Sourcing
Addressing structural sizing, forklift compatibility, port delivery protocols, and safety validation for engineering managers.
What specialized handling equipment is required to operate a Double Deep Pallet Racking system? +
Double deep configurations require specialized forklifts equipped with extended reach mechanisms. These include pantograph-type reach trucks (utilizing a scissor mechanism to extend forks into the second depth layer) or telescopic hydraulic fork attachments. When planning warehouse aisle widths, operators must account for the reach truck's extended turning radius, which typically ranges between 2.8 meters to 3.4 meters depending on chassis configuration and pallet profile.
How does HEDA Shelves guarantee structural safety under continuous seismic or heavy load operations? +
Our engineering design incorporates finite element analysis (FEA) compliant with FEM 10.2.02 and RMI specifications. All upright frames are secured via heavy-duty baseplates anchoring directly into concrete slabs using high-grade chemical or mechanical wedge anchors. Structural row spacers join back-to-back upright frames, significantly enhancing longitudinal and lateral torsional rigidity across the overall racking structure.
What parameters must be provided to receive a customized 2D CAD layout and structural load quotation? +
To deliver an engineered 3D structural proposal and accurate quotation, we require: (1) Warehouse clear height dimensions under the beam; (2) Architectural column grids, entry points, and fire sprinkler clearance; (3) Pallet specifications including depth, width, total height including goods, and maximum payload per pallet; (4) Mast lift height and turn radius of your designated reach truck; and (5) Ambient operational conditions (e.g., ambient warehouse, cold store, or chemical environment).
How does container packing prevent in-transit corrosion and transit bending during ocean freight? +
Every component is engineered for export container optimization. Upright frames and beams are systematically bundled with wooden battens, heavy-duty corrugated board, and moisture-resistant stretch wrap. Critical connection pins and baseplates are sealed in reinforced crates. All bundles are labeled to correspond directly with CAD assembly drawings, ensuring clear customs staging and rapid on-site assembly.
Can HEDA Shelves double deep systems be converted into automated radio shuttle racking later? +
Yes. Our modular design allows standard double deep frames to be retrofitted with heavy-duty galvanized shuttle guide rails and pallet supports. This flexibility protects capital investments, allowing facilities to shift from manual reach trucks to semi-automated radio shuttle operations as logistics throughput demands scale.
