In industrial shipping, details matter. One of the most overlooked decisions in equipment transport is the choice between a pallet and a skid. While the two terms are often used interchangeably, they are structurally different and serve distinct purposes.
For companies moving heavy machinery, aerospace components, semiconductor equipment, or high-value manufacturing systems, selecting the correct base platform directly affects safety, compliance, and overall shipment performance. A skid is not simply a wooden platform; it is a structural foundation that influences how weight is distributed and how a shipment performs from the factory floor to final delivery.
What Is a Skid in Shipping?
A skid is a single-deck load platform supported by longitudinal runners. Unlike a pallet, it does not have a bottom deck. This difference changes how the platform behaves under load. Without a bottom deck, a skid allows for direct contact between the runners and the supporting surface, which can improve stability for heavy equipment and allow controlled movement during positioning inside a facility.
Skids are commonly used for industrial machinery and oversized equipment that require secure anchoring. Because they are often engineered specifically for the equipment they support, they are frequently custom built rather than standardized. At Crating Technology, skid construction is treated as a structural design exercise where load weight, center of gravity, and transportation conditions are all evaluated before fabrication begins.
When Should a Skid Be Used Instead of a Pallet?
Skids are typically selected when strength and structural integration are more important than universal sizing. They are most appropriate in the following situations:
- Heavy Equipment Shipments: Industrial machinery and energy-sector components generate concentrated load stress that requires engineered runners to reduce deflection.
- Oversized or Irregular Dimensions: When equipment exceeds standard footprints, a custom base matches the asset’s exact footprint.
- Permanent Foundations: Some equipment remains bolted to its skid during storage or deployment.
- Integration into Custom Crating: In many projects, the skid becomes the floor system of a custom wood crate.

Engineering Considerations for Heavy Machinery
A standard pallet is rarely appropriate for high-density industrial equipment. When designing a skid, several factors must be evaluated:
- Static and dynamic load weight.
- Center of gravity offset.
- Transit vibration exposure.
- Long-term storage conditions.
Planning for regional logistics realities, such as those common throughout the Arizona Silicon Desert shipping network, ensures the skid performs under real-world conditions.
ISPM 15 and Export Compliance
When equipment is shipped internationally, wood packaging materials must meet ISPM 15 phytosanitary standards. Skids constructed from heat-treated lumber ensure compliance and prevent costly customs delays.
Skids as Part of a Complete Engineered System
In many cases, a skid is the starting point for:
- Custom foam fabrication solutions for vibration control.
- Vapor barrier packaging for moisture protection.
- Shock isolation components to prevent G-force damage.
Reusability and Sustainability
Reusable skid systems offer operational and environmental advantages. Organizations aligning with sustainability goals benefit from packaging strategies that reduce material waste and extend product lifecycle.
Operational Impact for Decision Makers
For procurement managers and logistics leaders, engineered skids provide:
- Improved load stability during handling.
- Reduced risk of structural deformation.
- Enhanced compliance for export shipments.
The decision is structural and financial. Selecting the correct foundation strengthens the entire shipment from the ground up. Explore further technical resources on the Crating Technology blog or request a tailored assessment for your next project.
