Wood
Pallets

The selection of wood species for pallet manufacturing represents a critical engineering decision that fundamentally impacts structural performance, cost efficiency, and service life. Southern yellow pine (Pinus palustris and Pinus taeda) dominates the East Coast pallet industry, accounting for approximately 43% of all pallet lumber consumption in the mid-Atlantic region. This prevalence stems from the species' exceptional strength-to-weight ratio, with an average specific gravity of 0.51 when kiln-dried to 12% moisture content, combined with regional abundance that minimizes transportation costs and supports rapid production cycles.

Hardwood species, particularly red oak (Quercus rubra) and white oak (Quercus alba), offer superior mechanical properties for demanding applications requiring maximum durability and impact resistance. Red oak exhibits a modulus of rupture of 14,300 psi and a modulus of elasticity of 1,820,000 psi, significantly exceeding softwood specifications. These characteristics make oak the preferred choice for automotive manufacturing environments where pallets may be subjected to repeated impact loading from automated handling systems moving powertrain components weighing 2,000-3,500 pounds. The dense cellular structure of hardwoods, with fiber saturation points typically between 25-30%, also provides enhanced resistance to compression perpendicular to grain, reducing deck board deflection under concentrated loads.

Mixed hardwood pallets incorporate a strategic combination of species to optimize cost-performance ratios. Manufacturers commonly use hardwood stringers for structural support while employing lower-grade softwood or mixed species for deck boards where load distribution reduces stress concentrations. This hybrid approach can reduce material costs by 18-25% compared to all-hardwood construction while maintaining 85-90% of the load-carrying capacity. Douglas fir (Pseudotsuga menziesii) serves as an excellent complementary species with its relatively high stiffness and moderate density of 0.48, bridging the performance gap between southern pine and hardwoods.

Material property variations within species require careful quality control during manufacturing. Southern yellow pine exhibits significant property differences between fast-growth plantation timber and slower-growing natural forest stands. Plantation-grown pine with growth rings spaced 6-8 rings per inch typically shows 15-20% lower bending strength compared to tighter-grained material with 10-14 rings per inch. Advanced pallet manufacturers implement visual grading protocols that classify lumber based on knot frequency, slope of grain, and growth ring density, ensuring consistent structural performance across production runs. The National Wooden Pallet and Container Association (NWPCA) Uniform Standard for Wood Pallets provides detailed grading criteria that correlate visual characteristics with mechanical properties, enabling manufacturers to match material quality to application requirements.

Stringer pallet construction represents the most economical and widely adopted design methodology, utilizing three longitudinal members (stringers) to support transverse deck boards. The standard 48x40-inch GMA pallet employs 2x4-inch stringers positioned at both edges and the centerline, creating a 19-20 inch spacing that optimizes load distribution for fork entry. Stringer dimensions follow engineered specifications that balance material efficiency with structural requirements: 1.5-inch actual thickness (2-inch nominal) provides adequate bending strength while minimizing lumber consumption, and 3.5-inch actual width (4-inch nominal) offers sufficient bearing surface to prevent localized crushing of deck boards under concentrated loads. Notched stringers, machined to create fork entry channels typically 9 inches wide and 1.5 inches deep, enable two-way fork access while reducing effective stringer depth at critical stress points.

Block pallet design employs nine individual blocks (cylindrical or rectangular solid wood pieces) positioned at strategic load-bearing points, offering superior four-way fork entry and enhanced racking stability. The nine-block configuration places blocks at all four corners, the centerpoint, and four intermediate positions, creating a distributed support network that excels in rack storage applications where concentrated support beam contact is critical. Block dimensions typically measure 3.5 x 3.5 inches in cross-section with heights ranging from 3.5 to 5.5 inches depending on pallet overall height requirements. This design increases lumber consumption by 12-18% compared to stringer pallets but delivers 35-40% greater racking capacity by eliminating stringer notches that create stress concentrations and reducing deck board spans between support points.

Deck board configuration significantly influences pallet performance characteristics and manufacturing efficiency. Standard GMA pallets utilize seven top deck boards spaced at 3.5-inch intervals, creating 0.5-inch gaps that facilitate fork entry while maintaining adequate bottom product support. Board width specifications of 3.5 inches (nominal 4-inch) represent an engineering compromise between coverage area and material optimization - wider boards would reduce manufacturing labor but increase waste during cutting operations and limit flexibility in accommodating length variations. Premium pallets may incorporate nine top deck boards with narrower spacing to enhance load stability for smaller carton footprints, while economy grades use five or six boards with wider gaps. Bottom deck boards typically number three to five, positioned directly beneath stringers to maximize load transfer efficiency while minimizing material consumption on the non-load-bearing surface.

Advanced engineering analysis using finite element modeling has revolutionized pallet design optimization, enabling manufacturers to predict failure modes and refine geometries before physical prototyping. Computer simulations model stress distributions under various loading scenarios, identifying critical failure points typically at the notched stringer sections where bending moment reaches maximum values. These analyses have demonstrated that increasing stringer depth by just 0.5 inches in notched regions can improve ultimate load capacity by 22-28%, leading to the development of reinforced stringer profiles. Material disposition strategies derived from FEA studies optimize board placement patterns, positioning higher-grade lumber at maximum stress locations while utilizing lower-grade material in less critical areas, achieving 15-20% material cost reductions without compromising structural integrity.

Modern pallet manufacturing integrates automated processing equipment with traditional woodworking techniques to achieve production rates exceeding 500 units per eight-hour shift in high-volume facilities. The process initiates with raw lumber receiving, where material undergoes visual inspection and moisture content verification using resistance-type or capacitance meters. Acceptable moisture ranges vary by application: kiln-dried lumber typically arrives at 12-18% moisture content for premium applications requiring dimensional stability, while green lumber at 19-25% moisture serves economy-grade production where cost minimization supersedes moisture-related shrinkage concerns. Lumber staging systems organize material by dimension and grade, feeding automated cut-to-length saws that process stringers and deck boards to precise specifications with tolerances of ±1/8 inch.

Assembly operations employ either manual nailing stations or automated pallet assembly systems depending on production volume and capital investment capacity. Manual assembly involves positioning deck boards on jig-mounted stringers while operators use pneumatic nail guns delivering 90-120 PSI air pressure to drive 8d or 10d ring-shank nails at specified locations. Skilled operators achieve cycle times of 90-120 seconds per pallet, maintaining quality through visual inspection and tactile feedback during fastener installation. Automated assembly lines utilize servo-driven board feeding systems that position components with ±2mm precision, followed by multi-head pneumatic or electromagnetic nailing systems that simultaneously drive 12-16 fasteners per operation cycle. These systems achieve production rates of 30-35 seconds per pallet while ensuring consistent nail depth and spacing that manual methods struggle to replicate across extended production runs.

Fastener selection and installation parameters critically influence structural performance and service life. Ring-shank nails, featuring annular ridges machined along the shank length, provide 40-50% greater withdrawal resistance compared to smooth-shank alternatives through mechanical interlocking with wood fibers. Typical specifications call for 8d nails (2.5 inches length, 0.131-inch diameter) for 5/8-inch deck boards or 10d nails (3 inches length, 0.148-inch diameter) for 3/4-inch to 1-inch thick components. Nail penetration depth requires careful control: insufficient penetration below 1.25 inches into stringers provides inadequate holding strength, while excessive penetration causing nail tip breakthrough on the opposite face creates safety hazards and stress concentration points that accelerate splitting. Advanced manufacturers implement nail depth monitoring systems using laser displacement sensors that verify each fastener achieves target penetration depths of 1.5-1.75 inches with 95% process capability.

Quality control protocols implemented by industry-leading manufacturers exceed minimum NWPCA standards, incorporating statistical process control methodologies that monitor critical-to-quality parameters throughout production. Dimensional verification occurs at multiple process stages: cut lumber measurements confirm saw accuracy, in-process checks during assembly ensure component positioning, and final inspection validates overall pallet dimensions against specifications. Load testing programs randomly select finished pallets for destructive testing, applying increasing loads until failure occurs to verify design load capacities maintain adequate safety factors. The NWPCA Uniform Standard specifies minimum performance criteria including fork tine penetration resistance, deck board deflection limits, and ultimate failure loads for various pallet classes. Third-party certification programs such as the Pallet Design System (PDS) provide engineering validation that pallet designs meet specified performance requirements, offering customers documented assurance of structural adequacy for their particular applications.

Moisture content management represents a critical control parameter affecting both immediate pallet performance and long-term dimensional stability. Wood's hygroscopic nature causes cellular structures to absorb or desorb water in response to ambient relative humidity, resulting in dimensional changes that impact pallet geometry and load-carrying capacity. The fiber saturation point, typically occurring at 25-30% moisture content depending on species, marks the threshold below which dimensional changes begin as water evacuates from cell walls rather than void spaces. Kiln-drying processes reduce lumber moisture to 12-18% through controlled heating cycles lasting 3-7 days at temperatures of 160-180°F, achieving equilibrium moisture content appropriate for typical warehouse environments maintaining 40-60% relative humidity. This controlled drying minimizes subsequent dimensional changes that could compromise pallet integrity or cause problems with automated handling systems requiring precise dimensional tolerances.

Heat treatment protocols mandated by International Standards for Phytosanitary Measures No. 15 (ISPM-15) require wood packaging materials in international trade achieve minimum core temperatures of 56°C (132.8°F) for minimum durations of 30 continuous minutes. This thermal exposure eliminates pest organisms including insects, nematodes, and fungi that might otherwise spread between countries, protecting global forest resources from invasive species. Heat treatment facilities employ specialized chambers equipped with sophisticated temperature monitoring systems featuring multiple probe thermocouples strategically positioned throughout lumber stacks to verify all material achieves required time-temperature profiles. Treatment cycles typically extend 12-24 hours including heating, holding, and cooling phases, with final verification provided by temperature chart recorders that document compliance. Successfully treated pallets receive permanent HT stamps applied with heat-resistant ink, displaying treatment facility registration numbers and IPPC logos certifying international shipping compliance.

Methyl bromide fumigation serves as an alternative ISPM-15 treatment method, though its usage continues declining due to environmental concerns and regulatory restrictions under the Montreal Protocol governing ozone-depleting substances. The fumigation process exposes wood packaging to methyl bromide gas concentrations of 48-64 grams per cubic meter for 16-24 hours at minimum temperatures of 10°C, achieving pest mortality through cellular respiration disruption. While methyl bromide effectively penetrates wood structures and requires shorter treatment durations than heat processes, safety considerations necessitate specialized facilities with gas-tight chambers, scrubbing systems for emission control, and extensive operator training. The treatment provides no residual protection after aeration, and some countries have banned methyl bromide imports entirely, leading most manufacturers to favor heat treatment for its broader acceptance and lower regulatory complexity.

Preservative treatments extend pallet service life in challenging environments involving outdoor storage, ground contact, or exposure to decay organisms. Chromated copper arsenate (CCA) pressure treatment, once dominant for outdoor wood applications, has been largely replaced by newer chemistries including alkaline copper quaternary (ACQ) and copper azole formulations that eliminate arsenic while maintaining decay resistance. The pressure treatment process involves placing pallets in sealed cylinders, drawing vacuum to evacuate air from wood cellular structures, introducing preservative solution under pressures of 100-250 PSI forcing chemicals deep into wood, and applying final vacuum to remove excess solution. Retention levels typically target 0.25-0.40 pounds of preservative per cubic foot for above-ground applications, with higher loadings of 0.60-1.0 PCF for ground-contact scenarios. Treated pallets require several days of air-drying before use to allow surface moisture evaporation and chemical fixation, emerging with service life expectations exceeding 15-20 years compared to 3-5 years for untreated softwood in similar applications.

Load capacity specifications encompass multiple performance parameters reflecting diverse loading scenarios encountered throughout pallet service life. Static load capacity defines the maximum weight a pallet supports when placed on a flat, uniform surface with load distributed evenly across the deck area, representing warehouse floor storage configurations. Standard 48x40-inch stringer pallets constructed from southern pine or mixed hardwoods typically achieve static load ratings of 2,500-3,000 pounds, with block-style designs reaching 4,000-5,000 pounds through enhanced load distribution and elimination of notched stringer stress concentrations. Dynamic load capacity, reduced to 25-35% of static values, reflects the additional stresses imposed during forklift handling, transportation vibration, and shock loading from pallet handling equipment impacts. These reduced working loads provide safety factors accounting for unknown load distributions, material property variations, and abuse during handling operations.

Racking load performance presents the most demanding structural challenge, concentrating pallet weight onto narrow support beams typically 3-4 inches wide positioned perpendicular to stringer direction. This configuration creates high bending moments in stringers that span between support points, with maximum stress occurring at mid-span where the moment arm reaches peak values. Rack loading simultaneously subjects deck boards to concentrated deflection between stringers, potentially causing board failure if lumber quality or fastener specifications prove inadequate. The coefficient of variation in wood mechanical properties, typically 15-20% for modulus of rupture, necessitates conservative design approaches incorporating safety factors of 3-4 relative to calculated ultimate loads. Pallet Design System (PDS) software, developed by Virginia Tech and the National Wooden Pallet & Container Association, enables engineers to predict pallet performance under racking loads by modeling specific configurations including lumber species, dimensions, fastener patterns, and support conditions.

Structural failure modes vary depending on pallet design, material properties, and loading conditions. Stringer bending failure represents the most common primary failure mechanism in racking scenarios, initiating at notch locations where reduced cross-sectional area and stress concentration factors of 1.8-2.2 create critical failure planes. Visible warning signs include gradual stringer deflection, cracking sounds from fiber rupture, and progressive splitting propagating from notch corners. Deck board failure occurs through bending overload when span lengths between stringers exceed capacity relative to board thickness and load magnitude, or through fastener pull-through when localized loads exceed nail withdrawal resistance. Block pallets exhibit different failure patterns including block crushing under compression loading, deck board failure similar to stringer designs, and fastener withdrawal from reduced penetration depths into thinner block components versus stringer members.

Long-term performance degradation results from multiple mechanisms including moisture cycling, mechanical wear, impact damage, and biological degradation. Moisture cycling causes progressive loosening of fastener connections as wood swells and shrinks with ambient humidity fluctuations, reducing clamping forces that maintain board-to-stringer contact. After 100-150 moisture cycles representing 2-3 years of warehouse storage, nail withdrawal resistance may decline 30-40% compared to initial values, increasing the risk of board detachment under racking loads. Impact damage from forklift tines, particularly at stringer notch corners and deck board edges, creates crack initiation sites that propagate under repeated loading through fatigue mechanisms. Pallets subjected to outdoor storage or high-humidity environments without preservative treatment experience biological degradation from decay fungi including white rot (Trametes versicolor) and brown rot (Postia placenta) species that enzymatically decompose cellulose and lignin, reducing mechanical properties 40-60% before visible damage becomes apparent. Service life optimization requires matching pallet specifications to actual application conditions, implementing preventive maintenance programs, and establishing replacement criteria based on objective inspection protocols.

Wood pallets represent one of the most sustainable packaging solutions available to modern supply chains, with environmental advantages spanning material sourcing, manufacturing efficiency, end-of-life disposal, and carbon sequestration benefits. Lumber utilized in pallet manufacturing typically derives from sustainably managed forests certified by organizations including the Forest Stewardship Council (FSC) and Sustainable Forestry Initiative (SFI), which implement harvesting practices maintaining long-term forest health and biodiversity. North American forests have expanded by approximately 2% over the past decade despite ongoing timber harvesting, demonstrating that current consumption rates remain below regeneration capacity. Additionally, pallet lumber grades accommodate material specifications that would otherwise lack viable markets, including lower-grade sawmill output unsuitable for construction or furniture applications, effectively increasing forest resource utilization efficiency and reducing waste.

Manufacturing energy consumption for wood pallets remains significantly lower compared to alternative materials including plastic, metal, or composite designs. Life cycle assessment studies conducted by independent research organizations have demonstrated that producing a standard 48x40-inch wood pallet requires approximately 15-20 kWh of energy when accounting for sawing, drying, and assembly operations, compared to 65-80 kWh for comparable injection-molded plastic pallets or 180-220 kWh for steel pallets. This energy advantage stems from wood's natural structural properties requiring minimal processing to achieve functional performance, versus plastics demanding polymerization from petroleum feedstocks or metals requiring ore extraction and high-temperature smelting. Furthermore, sawmill operations increasingly utilize wood waste products including sawdust, bark, and trim pieces as biomass fuel for kiln drying and facility heating, achieving 40-60% energy self-sufficiency that reduces fossil fuel dependence.

End-of-life disposal options for wood pallets encompass repair, recycling, repurposing, and energy recovery pathways that minimize landfill contributions and maximize resource utilization. Industry estimates suggest 90-95% of wood pallets entering the waste stream undergo some form of value recovery rather than direct disposal. Pallet repair operations refurbish damaged units by replacing broken deck boards or stringers, extending service life by 3-5 years at costs 30-50% below new pallet prices. Recycling facilities process beyond-repair pallets through grinding operations producing wood mulch for landscaping applications, animal bedding for agricultural operations, or raw material for engineered wood products including particleboard and medium-density fiberboard. Waste-to-energy facilities combust pallet waste generating electricity or process heat, recovering approximately 8,500-9,500 BTU per pound of wood, equivalent to coal on a weight basis.

Carbon sequestration benefits position wood pallets as climate-positive products that temporarily remove carbon dioxide from the atmospheric cycle. Trees absorb CO2 during photosynthesis, converting carbon into cellulose and lignin structural components that remain sequestered throughout wood product service life. A typical 48x40-inch pallet containing 40-50 pounds of wood stores approximately 40-50 pounds of CO2 equivalent, representing carbon that would otherwise contribute to atmospheric greenhouse gas concentrations. When multiplied across the estimated 2.5 billion pallets in active circulation in North America, the total carbon storage approaches 50-60 million metric tons of CO2 equivalent. This sequestration effect persists until wood eventually decomposes or undergoes combustion, providing climate benefits of 5-15 years for typical pallet service lives. Organizations pursuing carbon neutrality increasingly recognize wood product utilization as a legitimate strategy contributing to emission reduction goals, with some companies specifically preferring wood pallets over alternatives to enhance their sustainability metrics and environmental reporting.

A major automotive assembly plant in the Baltimore region faced escalating pallet replacement costs and product damage from structural failures during engine block transportation. Their existing mixed-species pallets, rated for 3,000 lbs, were failing after just 18-24 months under actual loads averaging 3,200 lbs. The plant consumed 2,400 pallets annually for internal material handling, with replacement costs of $38,000 per year plus $12,000 in product damage claims from pallet collapse incidents.

Engineering analysis revealed that stringer failure at notch locations was the primary failure mode, occurring when bending moments exceeded material capacity under asymmetric loading conditions. The solution involved transitioning to custom-designed hardwood pallets using red oak stringers dimensioned at 2.5 x 4.5 inches (versus standard 2x4) with optimized notch geometry reducing stress concentrations by 28%. Deck boards utilized 3/4-inch oak positioned at closer 3-inch spacing to minimize deflection and improve load distribution.

Implementation results exceeded expectations: the hardwood pallets demonstrated service life of 7-8 years versus 2 years previously, reducing annual replacement requirements from 2,400 to approximately 350 units. Although unit cost increased from $14 to $24, the total annual expenditure decreased to $19,600 (including reduced replacement frequency and eliminated damage claims), representing a 61% cost reduction. Additionally, the enhanced stiffness eliminated product shifting during transport, improving Just-In-Time delivery reliability and reducing assembly line disruptions by 40%.

The case demonstrates how initial investment in premium materials delivers substantial lifecycle cost advantages when applications involve severe service conditions. The plant subsequently extended the hardwood pallet specification to transmission assembly operations, achieving similar performance improvements and validating the engineering-driven material selection process.

A regional food distributor expanding into Canadian export markets required ISPM-15 compliant pallets for international shipments while maintaining cost-effectiveness for domestic operations. Their existing pallet supply included a mix of heat-treated and non-treated units, creating sorting complexity and risk of regulatory non-compliance. Export shipments represented 15% of volume but generated compliance concerns that consumed disproportionate quality control resources.

The company implemented a comprehensive heat treatment program in partnership with a certified pallet manufacturer. All incoming wood pallets underwent heat treatment to 56°C core temperature for 30+ minutes, with certification stamps applied per ISPM-15 requirements. The manufacturer invested in dedicated treatment chambers with 24-probe temperature monitoring systems ensuring uniform heat penetration throughout lumber stacks. Documentation systems tracked treatment batch numbers, enabling complete traceability for regulatory audits.

The program delivered multiple benefits beyond export compliance: heat treatment reduced pallet moisture content to 12-15%, improving dimensional stability and reducing weight by 8-12 pounds per unit. This weight reduction lowered transportation costs by $0.40-0.60 per pallet for outbound shipments. The controlled drying also eliminated mold growth issues that had occasionally affected pallets in humid warehouse environments during summer months. Product contamination risks declined to zero, enhancing food safety protocols.

Export volumes increased 35% over two years as compliance certainty enabled the company to pursue additional international contracts previously avoided due to regulatory complexity. The universal heat treatment approach eliminated sorting requirements between domestic and export pallets, reducing warehouse labor by 120 hours monthly. Total program costs including treatment premiums of $1.50 per pallet were offset by operational efficiencies and new revenue opportunities within 18 months, validating the strategic investment in compliance infrastructure.

A 200,000 square-foot cold storage facility experienced chronic pallet degradation problems stemming from moisture condensation during temperature cycling between -10°F storage and 70°F loading dock environments. Pallets absorbed condensation moisture during warm-up periods, with moisture content increasing from 14% to 22-25% after just 3-4 thermal cycles. This moisture absorption caused three critical problems: increased weight adding transportation costs, dimensional swelling creating racking fit issues, and accelerated biological degradation including mold growth and structural weakening.

Traditional pallets were failing after 18-24 months despite light loads averaging just 1,800 lbs, well below rated capacity. Investigation revealed that moisture cycling was driving failure through repeated swelling/shrinking that loosened fasteners and created splitting along grain patterns. Additionally, mold growth created food safety concerns and aesthetic problems with visible discoloration on stored product packaging. The facility consumed 4,500 pallets in inventory rotation with annual replacement of 2,200 units at $26,000 cost plus extensive quality control labor.

The solution involved transitioning to kiln-dried southern yellow pine pallets with initial moisture content of 10-12% and application of water-repellent surface treatments. Additionally, pallet design was modified to increase air circulation through wider board spacing (0.75-inch gaps versus 0.5-inch) and the facility implemented a pallet pre-conditioning protocol maintaining incoming pallets at 35-40°F for 24 hours before introduction to frozen storage. These measures reduced moisture absorption to 14-16% maximum, maintaining dimensional stability.

Results included extending average pallet service life to 5-6 years (3x improvement), eliminating mold growth incidents completely, and reducing weight gain to negligible levels saving approximately $8,000 annually in transportation costs. The pre-conditioning protocol added minimal operational complexity as pallets could stage in existing refrigerated dock space. Total annual pallet costs decreased to $9,800, representing 62% reduction while simultaneously improving food safety compliance and reducing quality control labor requirements by 180 hours annually.

A rapidly-growing e-commerce fulfillment center processing 25,000 orders daily encountered pallet failure rates of 3.2% during high-speed automated handling operations. Their material handling system incorporated automated guided vehicles (AGVs), robotic pallet shuttles moving at 400 feet/minute, and automated storage/retrieval systems (AS/RS) with acceleration rates of 1.5 m/s². Standard GMA pallets were experiencing premature failure through fastener withdrawal, deck board splitting, and stringer cracks at notch locations - failures that caused expensive system downtime averaging 45 minutes per incident.

Engineering analysis using high-speed video and accelerometer monitoring revealed that impact forces during pallet placement in AS/RS racks reached 8-12 G's, far exceeding conventional handling stress assumptions of 2-3 G's used in standard pallet design. These shock loads created instantaneous stress spikes that exceeded material capacity, initiating crack propagation that manifested as failures after 150-200 handling cycles rather than the expected 800-1,000 cycles for conventional systems.

The solution incorporated multiple engineering improvements: transition to block-style pallets eliminating notched stringers and distributing stress across nine support points; specification of kiln-dried hardwood for all structural components providing 25% higher modulus of rupture; implementation of spiral ring-shank nails offering 65% greater withdrawal resistance; and addition of metal corner reinforcements at high-stress connection points. Dimensional tolerances were tightened to ±1/8 inch to ensure consistent AS/RS system compatibility and prevent jamming incidents.

Implementation delivered dramatic improvements: pallet failure rates decreased to 0.3% (90% reduction), system downtime from pallet-related incidents fell to less than 2 hours monthly, and pallet service life extended from 200 to 1,400 handling cycles. Although unit costs increased from $12 to $21, the total cost per handling cycle decreased from $0.060 to $0.015 when accounting for replacement frequency and downtime costs. The fulfillment center estimated total annual savings of $185,000 including reduced downtime, lower replacement frequency, and decreased emergency pallet procurement at premium pricing. This case demonstrates how optimizing pallet specifications for actual operational stresses, rather than generic capacity ratings, delivers substantial performance and cost improvements in demanding automated handling environments.
