Dunnage Timber: Practical Use in Transport and Storage

Dunnage timber is used to support, separate, and stabilise loads during storage and transport. In real operations, it does the quiet work of protecting cargo, increasing friction, and creating clearance for forklifts or slings. When it’s chosen well, dunnage goes almost unnoticed. When it’s not, it becomes the reason loads shift, crush, or arrive damaged.

From our experience working with transport operators, warehouses, and heavy industry, timber dunnage remains widely used because it’s simple, adaptable, and easy to integrate with existing equipment.

What Dunnage Timber Is Used For

Timber dunnage is placed between cargo and floors, decks, or other goods to manage load behaviour. Common purposes include:

  • Spreading weight to avoid point loading
  • Creating airflow or drainage under cargo
  • Providing forklift clearance for safe lifting
  • Preventing direct contact between cargo and hard surfaces
  • Adding friction to reduce sliding during transport

In many cases, dunnage timber works alongside straps, chains, or blocking systems rather than replacing them.

Common Types of Timber Dunnage

Not all timber dunnage performs the same way. The differences show up quickly in high-load or repeat-use environments.

Solid Hardwood Dunnage
Traditional hardwood blocks are strong and readily available, but they can split, compress, or vary in size. Performance depends heavily on timber quality and moisture content.

Softwood Dunnage
Often used for single-use export or light loads. It’s lighter and cheaper, but not suited to repeated heavy-duty applications.

Engineered Timber Dunnage (LVL)
Laminated veneer lumber offers consistent dimensions, high compressive strength, and better resistance to crushing. When combined with rubber lining, it also delivers much higher friction than plain timber.

Dunnage Timber and Load Restraint

A common mistake is treating dunnage as decoration rather than a functional restraint element. Timber dunnage plays a key role in controlling movement at the base of a load.

Good dunnage:

  • Increases friction between load and deck
  • Helps prevent rolling or sideways shift
  • Reduces reliance on over-tightened straps

Poor dunnage:

  • Crushes under load
  • Slides on smooth surfaces
  • Forces restraint systems to work harder than intended

That’s why dunnage timber selection should always consider deck material, cargo weight, and transport mode.

Export and Compliance Considerations

For export shipments, timber dunnage often needs to be treated to meet biosecurity requirements. Heat treatment or fumigation may be required depending on destination and regulations.

Using compliant timber avoids delays, rejections, and rework at ports. Many operators choose engineered or processed timber options to simplify compliance and documentation.

Durability and Reuse

In high-cycle environments, durability matters. Timber dunnage that deforms or breaks quickly becomes a safety risk and a cost issue.

From what we see on site:

  • Consistent sizing improves loading speed and repeatability
  • Engineered timber lasts longer under heavy loads
  • Rubber-faced timber maintains grip over multiple uses
  • Reusable dunnage reduces waste and replacement effort

Planning for reuse and inspection helps keep operations predictable.

How We at Ferrier Industrial Work with Dunnage Timber

When we at Ferrier Industrial supply dunnage timber, we look at how it will actually be used — load type, weight, handling equipment, and transport conditions.

In many heavy-duty applications, we recommend engineered LVL dunnage with high-friction rubber lining to improve stability and service life. For other uses, compliant hardwood or softwood options may be appropriate.

We also support consistent specifications and reliable supply across Australia and New Zealand, so teams aren’t forced to substitute unsuitable materials when stock runs short.

Final Thought

Dunnage timber might look simple, but it plays a critical role in load stability and cargo protection. Choosing the right type — and using it correctly — often solves problems before straps, chains, or gates ever come into play.

If you’re dealing with shifting loads, crushed blocks, or inconsistent performance, it’s usually worth revisiting your dunnage choice. We’re always happy to share practical insight from the field.
