What Is Dunnage in Trucking?

Dunnage is essential in trucking and logistics. It refers to materials used to protect and secure cargo during transportation. Whether you’re managing a shipping container or loading a flatbed trailer, proper use of dunnage ensures your goods arrive safely and intact.

Understanding Dunnage and Its Role

Dunnage includes items like wood blocks, plastic, foam, bubble wrap, and air pillows. These materials fill empty spaces, prevent cargo movement, and cushion goods against shocks. Using effective dunnage helps maintain load stability and maximize the use of cargo space.

Why Proper Dunnage Matters

Using the right dunnage reduces cargo damage and improves safety on the road. For example, a flatbed carrying machinery without sufficient dunnage risks shifting loads, which can cause accidents or damage valuable equipment. Dunnage protects your investment and prevents costly claims.

Common Types of Dunnage in Trucking

Solid Materials

Wooden or plastic blocks and pallets provide strong support for heavy items. They help distribute weight evenly and stabilize the load. Learn more about our semi-trailer parts designed for secure cargo handling.

Bubble Wrap and Foam

These lightweight materials cushion fragile items like electronics or glass. Foam can be custom-shaped for irregular cargo. Check out our suspension systems that protect your vehicle and cargo during transit.

Kraft Paper and Air Pillows

Kraft paper fills gaps and adds a layer of protection. Air pillows are inflatable and adjustable to fill voids securely. Both options reduce cargo movement and absorb impact.

Benefits of Using Dunnage

• Cargo Protection: Prevents damage from shocks and shifting.

• Load Stability: Keeps cargo firmly in place during transit.

• Weight Distribution: Avoids stress on specific areas of your trailer.

• Compliance: Meets safety and transportation regulations.

• Cost Savings: Reduces losses from damaged goods and insurance claims.

How to Choose the Right Dunnage

Consider these factors when selecting dunnage:

• Cargo Type: Fragile, heavy, or irregular shapes need different protection.

• Weight: Heavier cargo requires sturdier dunnage.

• Transport Mode and Distance: Longer or rougher routes may need extra cushioning.

• Environmental Impact: Choose eco-friendly options if possible.
