Tucson: A Major Aerospace Hub
Tucson is one of the most important aerospace and defense centers in the United States. The city is home to Raytheon Missiles & Defense (now RTX), one of the largest missile manufacturing facilities in the world. Davis-Monthan Air Force Base houses the 309th Aerospace Maintenance and Regeneration Group (AMARG) — the military's primary aircraft storage and regeneration facility, managing over 4,400 aircraft. Bombardier, Ascent Aviation Services, Vector Launch, and dozens of smaller defense contractors and aerospace suppliers operate in the region.
This concentration of aerospace activity creates unique pallet requirements that standard off-the-shelf pallets simply cannot meet. Aerospace components are often oversized, extremely heavy, geometrically complex, high-value, and subject to strict shipping and handling specifications that govern everything from material selection to treatment certification.
Unique Requirements of Aerospace Pallets
Oversized Dimensions
Aerospace components frequently exceed standard pallet dimensions. Missile sections, wing assemblies, engine nacelles, avionics racks, and structural components may require pallets ranging from 60×48 inches to 120×96 inches or larger. Some applications demand even more extreme dimensions — we have built pallets exceeding 20 feet in length for specialized transport of fuselage sections.
Unlike standard pallets that follow the 48×40 GMA specification, aerospace pallets are designed around the specific component they will carry. Each pallet is essentially a custom-engineered shipping platform. Check our size guide for standard options, or contact us for fully custom engineering.
Heavy-Duty Load Ratings
Standard pallets are rated for 2,500 lbs dynamic load. Aerospace pallets frequently need to support 5,000, 10,000, or even 20,000+ pounds. This requires fundamentally different construction:
- Thicker stringers or blocks: 4×6 or 6×6 lumber instead of standard 2×4 or 3×4 stringers.
- Additional support points: Five or seven stringers instead of three, or a full block grid for even weight distribution.
- Hardwood construction: Oak, maple, or other dense hardwoods that provide superior load-bearing capacity compared to softwood pine.
- Reinforced fastening: Bolted joints, metal brackets, or heavy-gauge screws instead of standard pallet nails.
- Engineered deck configuration: Full deck coverage (no gaps between boards) to distribute concentrated loads and prevent component damage.
Precision Requirements
Aerospace shipping often involves custom crating systems where the pallet serves as the base of a multi-component packaging assembly. The pallet must meet tight dimensional tolerances — sometimes within 1/8 inch — to ensure proper fit with crate walls, internal blocking, foam cushioning systems, and tie-down hardware.
Standard recycled pallets vary by as much as 1/2 inch in overall dimensions due to board width variations and wear. Aerospace pallets are built to specification with measured and verified dimensions.
Cleanliness and Contamination Control
Some aerospace applications — particularly those involving sensitive electronics, optics, or clean-room manufactured components — require pallets that are free from loose debris, splinters, excess moisture, and chemical contamination. We use clean, graded lumber and deburr all cut edges to minimize contamination risk.
Materials Used in Aerospace Pallets
| Material | Application | Advantages |
|---|---|---|
| Southern Yellow Pine | General aerospace, moderate loads | Good strength-to-cost ratio, available in long lengths |
| Red Oak / White Oak | Heavy-duty, high-load applications | Superior hardness and load capacity |
| Hard Maple | Precision applications, smooth surfaces | Extremely dense, resists splintering |
| Douglas Fir | Oversized pallets requiring long clear spans | High bending strength, straight grain |
| Plywood deck overlay | Full-coverage deck for irregular loads | Uniform surface, no gaps, splinter-free |
| Composite / combination | Weight-sensitive applications | Reduced weight while maintaining strength |
ISPM-15 Heat Treatment for Military Export
A significant portion of Tucson's aerospace production is destined for international military customers through Foreign Military Sales (FMS) programs and direct commercial sales. All wood packaging materials shipped internationally must comply with ISPM-15 regulations.
For aerospace pallets, ISPM-15 compliance adds complexity because of the oversized dimensions involved. Standard heat treatment chambers accommodate pallets up to 48×48 inches. Oversized aerospace pallets may require larger chambers or treatment in sections before final assembly.
Our heat treatment facility is equipped to handle oversized pallets and provides full ISPM-15 certification including the required IPPC stamps and treatment documentation. For military shipments, we also provide supplemental documentation that satisfies Defense Contract Management Agency (DCMA) packaging inspection requirements.
Military Specification Compliance
Department of Defense shipments may need to comply with MIL-STD-2073 (Standard Practice for Military Packaging) and specific contract Data Item Descriptions (DIDs) that define packaging requirements. While we are not a MIL-STD-2073 packaging facility, our custom pallets are designed and built to integrate with crating and packaging systems that do meet these standards. We work directly with packaging engineers at defense contractors to ensure our pallet bases meet the specifications documented in their packaging plans.
Case Examples
Oversized Radar Component Pallet
A Tucson defense contractor required pallets for shipping large radar array components to a military installation in the Middle East. The components measured 96×72 inches and weighed 4,800 lbs each. We designed a block-style pallet using 6×6 oak blocks, 2×6 oak stringerboards, and a full plywood deck overlay. Each pallet was heat-treated to ISPM-15, marked on all four sides, and delivered with treatment certificates. The total unit cost was approximately 60% less than the contractor's previous supplier, who had been fabricating pallets from new dimensional lumber.
Precision Avionics Shipping Base
An avionics manufacturer needed pallets that would serve as the base platform for custom foam-lined shipping containers. Dimensional tolerance was critical: the pallet footprint had to be 42.000 × 36.000 inches ±0.125 inches to interface with the container's bolt-down pattern. We built these from kiln-dried hard maple with CNC-precision cut dimensions, pre-drilled bolt holes, and a sanded top deck. These pallets are reusable and cycle between the manufacturer and their customer, averaging 12 round trips before replacement.
Aircraft Engine Stand Pallet
An aircraft maintenance facility at Tucson International Airport required heavy-duty pallets to support engine maintenance stands during shipping. The stands weighed 3,200 lbs empty and the pallet needed to support the concentrated point loads of the stand's four feet. We designed a reinforced block pallet with doubled deck boards at each load point and steel corner brackets for tie-down attachment. The pallets were constructed from recycled Douglas Fir timbers recovered from decommissioned industrial pallets — delivering both cost savings and sustainability benefits.
The Design and Build Process
Our custom aerospace pallet process follows these steps:
- Consultation: We meet with your packaging or logistics engineer to understand the component dimensions, weight, handling requirements, destination, and any applicable specifications.
- Design: We produce a pallet design drawing with dimensions, materials, fastener specifications, and load ratings. For complex applications, we provide CAD drawings for your approval.
- Prototype: For new designs, we build a prototype for fit testing and approval before committing to production.
- Production: Approved designs go into production with full quality control — dimensional verification, load testing if required, and visual inspection.
- Treatment and certification: ISPM-15 heat treatment and marking, plus any additional documentation required by your contract.
- Delivery: We deliver to your facility on your schedule, including just-in-time delivery for production line integration.
Why Choose a Local Custom Pallet Supplier
Tucson aerospace companies have traditionally sourced custom pallets from packaging specialists in Phoenix, Los Angeles, or even out of state. Working with a local Tucson supplier offers significant advantages:
- Faster turnaround: No multi-day transit from distant fabrication shops. We can deliver prototypes within days and production orders within one to two weeks.
- Lower transportation cost: Custom oversized pallets are expensive to ship. Local fabrication eliminates freight.
- Responsive iteration: When a design needs modification — and in aerospace, it often does — local proximity means faster revision cycles.
- Security: Defense contracts may involve controlled unclassified information (CUI) about component dimensions and weights. Working with a local, trusted supplier reduces supply chain security concerns.
