Dunnage System

Designing a Dunnage System That Protects Your Cargo

When freight moves across thousands of kilometres—whether on trucks, in shipping containers, or across intermodal networks—what happens during those hours of motion matters enormously. Every bump, sway, and vibration poses a risk to the goods you’re responsible for getting safely to the destination. At Ferrier Industrial, we’ve spent decades helping logistics operators, steel manufacturers, and courier networks build a reliable dunnage system that handles these realities without creating supply chain complications or maintenance headaches.

A dunnage system isn’t just about throwing timber and rubber blocks under a coil or pallet. It’s a coordinated solution: the right materials, dimensions, fastening approach, and serviceability pathway all working together to stabilise cargo, reduce claims, simplify load-unload sequences, and extend product life. We know this from years of working alongside teams managing high-cycle operations in environments where downtime costs more than equipment.

The challenge most operations face is that generic dunnage systems—whether undersised timber, inconsistent rubber protection, or mismatched restraint points—don’t align with the specific physics of your freight or the constraints of your vehicles and handling equipment. That’s where engineering-led design, practical prototyping, and real-world testing make all the difference.

Understanding the Scope and Operational Context

Every dunnage system sits at the intersection of three pressures: protection (your cargo arrives undamaged), efficiency (loading and unloading don’t require custom tools or extended labour), and lifecycle value (the system remains serviceable, replaceable, and cost-effective over time).

In Australian and New Zealand logistics networks, these demands play out differently depending on whether you’re managing coil exports from a steel mill, consolidating mixed freight in a distribution centre, or ensuring postal parcels don’t shift in a last-mile delivery van. The dunnage approach for a six-tonne coil in an ISO container is worlds apart from the lightweight restraint needed for courier totes in a networked cage system. Yet both share fundamental principles: load distribution, friction engagement, and friction stability that we engineer into every solution.

Many operations inherit cobbled-together approaches—some timber from one supplier, straps from another, cradles from a third—and discover too late that they don’t interface cleanly, consume excessive warehouse space, or require constant replacement. A properly designed system, by contrast, reduces procurement friction, cuts spares inventory, and often pays for itself through damage reduction and faster throughput alone.

We’ve found that the best dunnage systems aren’t complex; they’re coherent. They fit your existing equipment interfaces (pallets, cages, vehicle decks), reflect your load profiles (weight, shape, fragility), and align with your team’s training and maintenance capacity.

Our Approach to Dunnage Solutions

At Ferrier Industrial, we focus on engineered solutions across three distinct areas: high-friction timber dunnage for heavy industry; rubber-based restraint and cushioning for transport; and bespoke composite systems for specialised loads.

LVL High-Friction Dunnage. We work with engineered laminated-veneer lumber (LVL) sourced from renewable forests and lined with vulcanised rubber. This combination gives you multi-use durability—especially important for steel operations moving coils repeatedly through the same transport patterns. The rubber lining maintains friction engagement even after multiple load cycles, and the engineered timber doesn’t warp, split, or lose structural integrity the way air-seasoned timber often does.

Coil and Sheet Restraint Equipment. For heavy industry, we’ve spent three decades perfecting systems that hold coils stable in transit without requiring specialised forklifts or custom load sequences at either end. This means faster load-unload, fewer damage claims, and the ability to handle varying coil diameters and weights in mixed container loads.

Truck Cradles and Composite Blocks. Vulcanised rubber bonded to steel frames provides vibration damping and load stability for intermodal and truck transport. We also work with hardwood, foam, and specialty blocks tailored to specific freight profiles—whether that’s precision electronics, agricultural products, or chemical shipments requiring anti-static or moisture-control properties.

Core features across all our dunnage solutions:

• Dimensions and specifications engineered to your exact load profile and vehicle constraints
• Rapid prototyping and fit-checks against your existing handling equipment (pallets, cages, vehicle decks, conveyors)
• Modular, nesting designs to maximise empty-return space and storage efficiency
• High-cycle durability with documented service life (our coil corners regularly perform for more than a decade without replacement)
• Full spares availability and serviceability pathways so a worn component doesn’t ground your entire supply chain

Designing for Real-World Freight Protection

The physics of load stability. A dunnage system works by creating multiple points of contact between your cargo and the vehicle or container structure, distributing weight evenly and preventing shift. For coils, that’s vertical blocks at the bore and horizontal restraint at the edges. For palletised freight, it’s strategic placement under high-stress points. For courier operations, it’s friction mats and modular cage systems that prevent sliding without requiring strapping.

The surface finish matters profoundly. A smooth timber dunnage block under a coil allows slippage under braking or turning; add a vulcanised rubber lining with a coefficient of friction greater than 0.60, and you’ve transformed that same block into a friction anchor. We’ve tested this across thousands of journeys—the difference between a generic timber block and a high-friction engineered system is often the difference between zero damage and a costly claim.

Restraint integration. Many operations underestimate how much the dunnage system itself contributes to overall restraint. If your timber blocks are too small, too soft, or poorly positioned, you’ll compensate with heavier strapping—which adds weight, takes longer to secure, and can damage goods. By contrast, a dunnage system engineered to handle half your load stability through friction means your straps need only manage the remaining movement, reducing strap count and labour time significantly.

Material selection and trade-offs. Timber is lighter and lower-cost upfront; rubber-lined timber is heavier and more durable; composite blocks offer specialised properties (anti-static, moisture-wicking) at a premium. The “best” choice depends on whether you’re optimising for first cost, service life, specific load requirements, or environmental goals. At Ferrier Industrial, we help teams map these trade-offs against their actual operational constraints and throughput targets.

Key Considerations When Specifying a Dunnage System

Before committing to any new dunnage system, evaluators typically weigh several critical factors:

• Spec fit and durability for your specific loads. A system designed for coil transport won’t reliably protect dimensional timber or precision machinery. Get the material type, hardness, and friction properties right for your freight profile.
• Integration with existing equipment. Will the dunnage nest efficiently in your pallets? Fit through your cage footprint? Interface cleanly with your vehicle decks and loading sequences? Misalignment here creates operational friction before the goods even leave the warehouse.
• Service life and maintenance. Does the dunnage degrade predictably, or do you face premature failures that halt operations? Are spare components readily available, or do you need to order complete replacements at significant lead times?
• Total cost of ownership. Factor in purchase price, storage footprint, labour to assemble/disassemble, replacement frequency, and damage reduction. A higher-priced engineered dunnage system often yields lower total cost-in-use than cheaper alternatives that wear out quickly or require constant supplementary restraint.
• Safety and ergonomics. Can your team handle, position, and secure the dunnage safely? Does it create sharp edges, lifting hazards, or pinch points? A well-designed system reduces manual handling strain and improves chain-of-custody visibility.
• Sustainability pathway. Is the dunnage reusable, repairable, or recyclable at end of life? For operators working toward circular practices or ESG commitments, this increasingly influences procurement decisions.

These considerations shape every conversation we have:

• Measure your actual load profiles (weight, dimensions, frequency) rather than guessing.
• Involve your handling team—they know where friction develops and what slows throughput.
• Request samples and run a controlled pilot before full rollout to validate fit and performance.
• Plan for spares from day one; the best dunnage system fails if replacement blocks take months to source.
• Document baseline damage rates before implementation so you can measure improvement credibly.

Implementing a Coordinated Dunnage System

At Ferrier Industrial, we approach a new dunnage system as a discovery-to-support journey. We begin by understanding your current load profiles, routes, equipment interfaces, and safety or sustainability goals. We then design prototypes, test them against your actual freight and handling sequences, measure results (damage rates, loading time, maintenance cycles), and then roll out at scale with JIT delivery and consignment stock to ensure you never run short.

Our facilities in Auckland and NSW allow us to rapidly prototype in-house, conduct fit-checks, and manufacture custom blocks to your exact specifications. We also leverage long-standing manufacturing relationships across Southeast Asia and the USA for scaled production, ensuring supply continuity regardless of demand fluctuations.

We see ourselves as an extension of your operations team. When you uncover a wear pattern after six months, we adjust block dimensions or material properties. When your fleet expands, we scale production without lead-time surprises. When sustainability mandates change, we help transition to recyclable or renewable-sourced materials. That’s not just vendor service; it’s partnership.

Practical Steps for Dunnage System Selection and Deployment

If you’re evaluating a new dunnage system or upgrading an existing one, we’d suggest starting with these practical steps:

• Audit your current state. Document your existing dunnage inventory, failure patterns, storage footprint, and handling labour. Identify where damage occurs and what causes speed-ups or stoppages. This baseline makes improvement measurable.
• Profile your freight. Gather weight, dimensions, and material fragility for your top volume lanes. Not every shipment needs the same protection level; segmentation often reveals opportunities for more cost-effective solutions.
• Map your equipment interfaces. Confirm dimensions for pallets, cages, vehicle decks, conveyors, and restraint attachment points. Dunnage that doesn’t nest cleanly wastes space; blocks that don’t align with attachment points require workarounds.
• Specify material and friction properties. High-cycle coil transport demands different vulcanised rubber durability than once-per-route LTL freight. Talk to your supplier about material selection trade-offs.
• Request samples and pilot options. A half-day trial in your actual warehouse with your actual teams often reveals fit issues that drawings alone won’t catch.
• Plan spares strategy. Agree upfront on spare-block availability, replacement lead times, and how pricing scales for consumable items. A dunnage system is only as good as your ability to maintain it.

How We Support Dunnage System Success

We know that specifying a dunnage system is one thing; keeping it performing reliably over years of service is another. That’s why we design with serviceability and continuity at the core.

When we deliver a dunnage system to an operation, we also supply a parts catalogue, dimensional drawings, and contact protocols. If a block wears or cracks, you order a replacement quickly; our team confirms the specification, manufactures it if needed, and ships it. We track wear patterns across your shipments so we can proactively suggest improvements—maybe the rubber lining needs a slightly higher durometer for your route, or the block geometry could shift to reduce edge stress.

For large-scale rollouts, we work with JIT and consignment stocking models. That means you hold minimal inventory; we manage the stock at a local distribution point and replenish as you consume. This reduces your warehouse footprint and capital tied up in spare parts, while ensuring zero stockouts interrupt your operations.

We also commit to design continuity. If your freight profile or equipment interfaces change, we adapt the dunnage system rather than making you source from a new supplier. That might mean new drawings, pilot testing, or a phased rollout—but the goal is always to minimise disruption to your operations.

Looking Forward: Dunnage System Evolution

The dunnage systems we build today reflect changing priorities across ANZ logistics. Operators want lighter solutions to reduce fuel costs, but also want durability to avoid frequent replacement. They want to minimise timber use for sustainability reasons, but also want proven materials with long track records. They want faster load-unload sequences, but also need auditable restraint documentation for compliance.

These aren’t contradictory—they just require thoughtful engineering. A high-friction engineered-timber dunnage system with rubber lining weighs less than traditional hardwood blocks, outlasts them significantly, and reduces load time because friction engagement is more reliable. Renewable-sourced LVL with responsible forestry certification meets sustainability goals without sacrificing performance. Modular, nesting designs cut storage footprint by half, freeing warehouse space for other uses.

At Ferrier Industrial, we’re constantly exploring how to evolve our dunnage systems to meet these shifting requirements. We collaborate with partners on bio-based resin options, test new rubber formulations, and share learnings with major operators so the entire industry improves.

Getting Started with Your Dunnage System

If you’re managing logistics operations, a manufacturing export function, or a postal and courier network, the dunnage system you choose influences safety, throughput, and cost-in-use every single day. We’d welcome a conversation about your current approach and what a tailored dunnage system might unlock.

We’d ask you to share your freight profiles, volume patterns, and equipment constraints. We’ll propose concept options, provide samples if useful, and outline a pilot plan so you can validate performance before committing to full-scale deployment.

At Ferrier Industrial, we don’t promise miracle outcomes or provide generic one-size-fits-all blocks. We do promise engineering rigour, operational candour, and a genuine partnership to keep your cargo protected and your teams working safely and efficiently. If that approach resonates, we’d like to hear from you.
