Anti-Slip Mats for Cargo

How do anti-slip mats improve cargo securing?

In professional transport, cargo rarely shifts because the straps are weak. In most cases the real problem is too little friction between the load and the loading surface. Anti-slip mats fix exactly that: chosen and calculated correctly, they increase friction, reduce the required lashing force, and improve overall safety. Below is how to select them and how to work out the effect in line with EN 12195.

Why does cargo shift?

Cargo moves when the horizontal acceleration force exceeds the available friction between the load and the trailer floor. So the lower the friction, the more work the straps must do — and the more straps you need. These are typical friction coefficients:

In other words, a good mat roughly triples the frictional resistance — which is why it does so much of the securing work for you. That effect feeds straight into the LC calculation and the tie-down method in the 5 cargo securing methods.

How do you choose the right anti-slip mats?

1. Check the certified friction coefficient (μ)

For professional cargo securing, use μ ≥ 0.6 as the minimum, and μ ≥ 0.8 for heavy or high-risk cargo. Always ask for test certification: real, documented μ data is what makes the load calculation valid and the load audit-proof.

2. Select the correct thickness

Match the thickness to the cargo weight and the floor condition:

Thicker mats compensate for uneven floors, increase the contact area and reduce point-load compression. However, if a mat compresses too much under load, its effective friction drops — so do not under-spec the thickness for heavy cargo.

3. Verify load capacity and compression resistance

The mat must withstand the static vertical load, the dynamic forces of braking and cornering, and point loads from machine feet or concentrated weight. If the material collapses under pressure, its friction performance becomes unreliable.

4. Consider the mode of transport

Different modes create different dynamic forces: road transport sees emergency braking up to 0.8 g forward; rail brings longitudinal shock; sea freight adds roll and pitch; and multimodal combines them. Therefore container and maritime transport call for higher safety margins.

How much lashing do anti-slip mats save?

The maths is simple, and it makes the case on its own. Take a 1,000 kg load under emergency braking (0.8 g), which produces about 800 daN of forward force. Friction holds part of it (weight × μ), and the straps hold the rest:

So the mat cuts the force the straps must resist from 600 daN to 200 daN — a threefold reduction, and with it far fewer lashings. That is the single cheapest way to bring a difficult strap-count calculation back under control.

Where should you place the mats?

Mats work only under full, supported contact. So place them under all load-bearing points, give full surface contact, and never leave a mat suspended or partly unsupported. In practice:

• At least two strips per pallet; full pallet-width coverage is better.
• Heavy or high-value cargo: full-surface coverage.
• Long cargo: strips every 50–80 cm for uniform load distribution.
• Machinery: solid sheets under each support foot to prevent tilting or uneven pressure.

Common mistakes with anti-slip mats

• Using dirty, oily or wet mats (friction collapses)
• Placing mats only at the edges
• Mixing different thicknesses under one load
• Reusing damaged or over-compressed mats
• Skipping the formal calculation for heavy cargo

When are anti-slip mats not enough?

Mats increase friction, but they do not replace lashing. Additional securing stays mandatory for high centre-of-gravity cargo, unstable or flexible packaging, over-height loads, and containerised freight exposed to maritime forces. Professional securing always combines friction and mechanical restraint — and both belong on your pre-departure checklist. Missing mats are also a fineable finding at inspection, as our guide to EU lashing fines shows.

FAQ: anti-slip mats for cargo

How much friction does an anti-slip mat add?

A certified anti-slip mat raises the friction coefficient from about 0.2 on a bare floor to roughly 0.6 (up to 0.8) — around three times more grip. For a 1,000 kg load under 0.8 g braking, that shifts 400 daN from the straps to friction, cutting the number of lashings you need.

What friction coefficient should an anti-slip mat have?

Use μ ≥ 0.6 for professional cargo securing, and μ ≥ 0.8 for heavy or high-risk cargo. Always ask for test certification, because only documented μ values make the load-securing calculation valid at an audit or roadside inspection.

How thick should an anti-slip mat be?

Match thickness to the load: 3–4 mm for light pallets, 5–6 mm for standard freight, and 8–10 mm for heavy machinery or steel coils. Thicker mats absorb uneven floors and point loads; too thin, and the mat compresses and loses friction.

Do anti-slip mats replace lashing straps?

No. Mats increase friction and reduce how many straps you need, but they never replace mechanical securing. High centre-of-gravity, unstable or over-height loads always require lashing as well. Professional securing combines friction and restraint.

Where do you place anti-slip mats under a load?

Under all load-bearing points, with full supported contact — never suspended or partly unsupported. Use at least two strips per pallet (full width is better), strips every 50–80 cm under long cargo, and solid sheets under each foot of machinery.
