GXM Pallet Shelving Heavy Duty System
Engineered roll-formed industrial selective frame adaptable into heavy double deep configurations with reinforced base plates and structural load distribution beams.
Engineering Density: High-Throughput Warehouse Space Optimization
Industrial warehousing in the post-expansion economy faces persistent pressures: elevated land-acquisition valuations, rising square-meter building rates, and operational overheads. In response, global procurement managers are turning to engineered Double Deep Racking Systems to achieve a balance between spatial footprint and load accessibility.
Footprint Consolidation
By placing two pallet positions back-to-back from a single operating aisle, Double Deep systems eliminate unnecessary access corridors, cutting aisle consumption by up to 30% to 40% compared to standard selective setups.
Structural Compliance
Fabricated strictly to European EN 15512:2020 principles and certified for CE compliance, every upright frame and connector lock maintains calculated structural tolerances under rigorous load and seismic shifts.
Turnkey Throughput
Designed for immediate pairing with pantograph reach trucks and deep-reach attachments, facilitating higher pallet storage per cubic meter without necessitating fully automated installations.

Engineering Anatomy of Double Deep Racking Systems
A double deep configuration is not merely two selective racks pushed together; it demands precise calculations of structural beam deflection, safety margin tolerances, and slab anchorage requirements.
Load Dynamics & Beam Deflection Criteria
Under European standard EN 15512 and RMI/ANSI MH16.1 specifications, beam deflection is held to a maximum threshold of L/200 under fully distributed working loads. For deep positions where fork reach deflection contributes dynamic live impact, our beams are cold-formed from high-tensile structural coil (Q355B / S355JR equivalents) with welded high-strength 4- or 5-claw connectors.
This design counters the torsional twisting forces introduced when a pantograph reach mechanism extends deep into the second pallet slot, maintaining beam integrity and horizontal plane stability over hundreds of thousands of duty cycles.
Upright Anchorage & Seismic Integrity
In double deep arrays, rear pallet placement exerts uneven horizontal moment loads across frame rows. Our engineering methodology involves:
- Heavy-duty row spacers that lock inner columns into unified, stiffened structural trusses.
- Extended base plate design engineered for chemical anchor bolts to maximize effective embedment into the concrete floor slab.
- Custom diagonal bracing geometries evaluated for localized seismic acceleration coefficients (Ss and S1 ratings).
| System Architecture | Floor Space Utilization | Pallet Selectivity | Forklift Equipment Match | Capital Cost Ratio |

| Radio Shuttle Automation | Maximum (~80%) | Lane Dependent (FIFO/LIFO) | Standard Forklift + Shuttle Unit | Capital Intensive (2.8x) |
| Drive-In Storage | Very High (~75%) | Strictly LIFO (Low Selectivity) | Drive-in Compatible Cab Reach | Moderate (1.3x) |

Frequently Asked Questions: Global Sourcing & Engineering
Expert technical insights to help your engineering and procurement teams make informed decisions.
What is the typical pallet selectivity ratio in a double deep racking design?
Double deep racking provides 50% immediate selectivity. Because pallets are stored two rows deep, accessing the rear pallet requires that the front slot be empty or temporarily moved. This configuration operates optimally when SKUs are grouped into multiples of two or more pallets (e.g., medium-to-fast turnover goods, homogeneous batches, or paired pallet replenishment strategies), balancing density against retrieval cycles.
Which specific forklift attachments are required to operate double deep racks?
Operators require either a specialized pantograph double-reach truck or a standard reach truck fitted with hydraulic telescopic fork extensions. When calculating aisle widths, facility planners must account for the chassis length of the deep-reach truck plus the required turning radius, which typically results in an aisle clearance between 3.0 to 3.4 meters, depending on pallet dimensions.
How does CE certification affect rack procurement for European and international projects?
CE Certification affirms that our structural components comply fully with EN 1090-1 execution standards, factory production control procedures (FPC), and EN 15512 static load modeling. For importers, this provides legal compliance with European building directives, simplifies local municipal permitting, guarantees steel chemical traceability, and streamlines facility property insurance approval.
Can an existing single-selective pallet rack system be converted into double deep?
Yes, provided the concrete slab compressive strength and thickness permit higher concentrated baseplate loadings, and existing upright frames can be connected via engineered row spacers. Furthermore, fork entry beams often require recalculation to handle the higher point loads associated with deep-reach insertions. Our structural engineering department can audit your existing CAD layout to establish feasibility.
What critical details are required to obtain a rapid engineering quotation?
To produce an optimized structural layout and bill of materials, provide: (1) Facility DWG/CAD architectural drawings indicating clear height under roof joists, (2) Pallet dimensions (width, depth, height) including overhanging cargo, (3) Maximum gross pallet weight, (4) Specific forklift models and mast staging heights, and (5) Local seismic zone ratings or building ZIP codes.
