A shifted coil on a flatbed. A pallet that’s walked sideways inside a container during transit. A sheet pack that’s arrived with edge damage because the only thing between it and the container wall was hope. We at Ferrier Industrial hear these stories regularly, and they almost always trace back to the same root cause — load restraints that weren’t matched to the cargo, the vehicle, or the route.

Getting restraint right isn’t complicated, but it does require more thought than grabbing whatever strap or chock is nearest. The freight environment across Australia and New Zealand throws up specific challenges: long-haul distances, mixed intermodal movements, temperature swings, and road surfaces that test every connection point between cargo and transport platform.

What Counts as Load Restraint — And What Gets Overlooked

When people think about cargo restraint, ratchet straps tend to come first. They’re visible, familiar, and often the only restraint method a driver interacts with directly. But effective cargo restraint is a system, not a single product. It includes everything that prevents movement — friction, blocking, bracing, lashing, and containment — working together.

High-friction rubber mats sit beneath loads to raise the static friction coefficient between cargo and deck. Dunnage — whether hardwood, engineered LVL timber, or foam — fills gaps and distributes pressure. Airbags brace loads laterally inside containers and rail wagons. Chain protectors prevent lashing hardware from cutting into product edges. Cradles hold cylindrical loads like coils in position without relying solely on downward strap force.

Each of these elements reduces the total lashing force required. That matters because over-tensioning straps damages product, fatigues hardware faster, and still won’t stop a load from shifting if the friction underneath is too low.

At Ferrier Industrial, we think of cargo securing as layered. Start with the base — friction and blocking. Then add lashing. Then consider edge protection and containment. Skip a layer and the system has a gap, no matter how many straps you add.

Our restraint product families cover the full layered approach:

• Friction and blocking — high-friction rubber mats, LVL and hardwood dunnage, vulcanised rubber truck cradles, and foam blocks that raise base friction and prevent initial movement
• Lashing and tensioning — ratchet strops and cargo straps in weather-resistant polyester, bore vertical and horizontal coil restraint corners in cold-rolled steel with rubber faces, and chain protectors that prevent lashing hardware from damaging product edges
• Containment and bracing — dunnage airbags for void fill in containers and rail wagons, edge and impact protection in extruded plastics, and VCI packaging for corrosion-sensitive metals in transit

Matching Restraint Methods to Cargo Type

Coil and Sheet Restraint for Steel Transport

Steel coils and sheet packs are among the most demanding loads to restrain. They’re heavy, they concentrate force on small contact areas, and cylindrical coils want to roll. Conventional strapping alone isn’t enough.

We’ve supplied coil and sheet restraint equipment to steel producers and transport operators for decades. Our bore vertical coil restraint corners — fabricated from cold-rolled steel with vulcanised rubber faces — locate into the coil bore and lock against the container or vehicle structure. They’re engineered to resist forces equivalent to the full weight of the coil under emergency braking or cornering, and they’ve been in continuous field service for well over a decade without structural failure.

For horizontal coil transport, we supply bore restraint equipment that prevents axial and lateral movement. Truck cradles in vulcanised moulded rubber hold coils stable on the deck, damping vibration and preventing metal-on-metal contact. These cradles conform to specific diameter ranges and have been running maintenance-free on fleet vehicles for years.

Single edge chain protectors — stainless pressings with vulcanised rubber — prevent transport chains from biting into coil edges. It’s a small component, but edge damage from chain contact is one of the most common quality claims in steel logistics.

General Freight and Mixed Loads

Mixed freight presents a different restraint challenge. Load profiles change every trip. Heights, weights, and surface textures vary across pallets on the same vehicle. The restraint system needs to be adaptable without being improvised.

Our general transport restraint range covers this ground. Ratchet strops and cargo straps in high-strength polyester handle direct lashing across a wide range of load shapes. Load-restraint rubber mats — with a static friction coefficient above the standard threshold — sit beneath pallets or between load layers to reduce the number of straps needed. Dunnage airbags fill voids in containers and rail wagons, applying lateral pressure to prevent load shift during transit.

These aren’t specialty items reserved for unusual loads. They’re daily-use products that need to perform reliably across thousands of cycles. We specify materials and construction to suit weather exposure, UV, abrasion, and the rough handling that comes with commercial freight operations.

Restraint in Postal and Courier Networks

Load restraints in postal and courier environments look different from heavy industry, but the underlying principles are identical. Parcels and totes inside roll cages need to stay contained during truck movement. Cages themselves need to be secured to the vehicle deck. Bikes carrying front and rear cargo loads need balanced weight distribution to keep the rider safe.

We supply network cages and trolleys with latching systems that prevent content spillage during transit and cross-dock transfer. For vehicle loading, our restraint solutions include track-mounted systems and cargo bars that hold cages in position without requiring the driver to rig individual lashing points each trip.

Our delivery bike platforms use balanced carrier designs — front and rear — so that tote weight doesn’t compromise steering or braking. It’s restraint at a different scale, but the objective is the same: keep goods secure and keep people safe.

What Makes Load Restraints Fail

Restraint failures rarely happen because of a single dramatic event. More often, they accumulate. A mat that’s been left in the sun and lost its friction properties. A strap with frayed stitching at the ratchet anchor. A cradle that’s been used outside its specified diameter range. Dunnage that’s absorbed moisture and softened.

Inspection and replacement cycles matter more than most operators realise. We design our products for high-cycle durability, but every restraint component has a service life. Vulcanised rubber degrades under sustained UV exposure. Polyester webbing loses strength after repeated wet-dry cycles. Even steel restraint hardware develops fatigue over time.

Procurement teams evaluating load restraint suppliers should ask about expected service life under realistic conditions — not laboratory conditions. They should also ask about spares. A restraint system is only as reliable as the weakest component, and if replacing a worn rubber face or a damaged ratchet mechanism means sourcing an entirely new assembly, costs escalate quickly.

Selecting Load Restraints: Factors That Matter

• Cargo characteristics — weight, shape, surface texture, fragility, and centre of gravity all determine which combination of friction, blocking, lashing, and containment is appropriate
• Vehicle and container interface — deck material, tie-down points, internal dimensions, and door configurations affect which restraint methods can physically be deployed
• Route and mode — road, rail, and sea each impose different dynamic forces; intermodal loads that transition between modes need restraint that works across all of them without being re-rigged at every interchange
• Regulatory and client standards — transport operators and shippers often have specific load-restraint guidelines that go beyond general regulations; compliance with these standards is a procurement requirement, not an optional extra
• Service life and total cost in use — a cheaper strap that lasts half as long isn’t cheaper; restraint economics should account for inspection, replacement, and the cost of damage claims when components fail prematurely

How We Approach Load Restraint at Ferrier Industrial

Our involvement with cargo restraint goes back to our earliest years supplying the steel industry. Since the early nineteen-nineties, we’ve worked alongside producers and transport operators to develop restraint systems that meet real operational demands — not just theoretical load calculations.

We start every engagement with a site review. We look at the cargo, the vehicle or container, the loading and unloading process, and the route profile. From there, we design a restraint approach that combines the right products in the right configuration. Often that means custom work — a cradle sized to a specific coil diameter, a dunnage profile cut to fit a particular deck layout, or a chain protector shaped to a non-standard lashing path.

Our manufacturing and supply network covers New Zealand and Australia, with partner production in China, Vietnam, Thailand, and the USA. We run JIT delivery and consignment-stock programmes so that replacement mats, straps, dunnage, and hardware components are available when they’re needed. QA includes incoming and final inspection with traceability on safety-critical items, and we feed field performance data back into product development.

Load restraints are one of the areas where we’re most confident in our depth. We’ve seen what works and what doesn’t across steel mills, logistics yards, postal hubs, and mining operations — and that experience shapes every recommendation we make.

Practical Steps for Specifying Restraint Equipment

• Map your cargo types, weights, and load configurations, then identify which restraint methods (friction, blocking, lashing, containment) apply to each — a single restraint product rarely covers every scenario in a mixed fleet
• Review your current restraint inventory for condition and compliance; worn mats, frayed straps, and deformed cradles should be flagged for replacement before they contribute to a load shift incident
• Specify restraint products by performance criteria (friction coefficient, breaking strength, temperature range, UV resistance) rather than by brand familiarity alone — this ensures you’re comparing like with like across suppliers
• Confirm that your supplier can provide spares for individual components (rubber faces, ratchet mechanisms, retaining pins) rather than requiring full-assembly replacement when a single part wears
• Request a site review and fit-check before committing to volume orders, particularly for bespoke items like coil cradles, bore restraint corners, or custom dunnage profiles — field validation catches interface issues that drawings sometimes miss
