Quick Answer: We rate our canopies' roof load as a static rating graded by material and thickness — 150 kg for 1.5 mm galvanized steel, 200 kg for 2.0 mm aluminium alloy, 500 kg for 3.0 mm aluminium alloy — and the 500 kg figure comes from a filmed static load test, not a datasheet. "Static" means the load parked on a stationary canopy (a rooftop tent with people inside). It is not a dynamic driving rating; the only roof load you carry while driving is the tent itself, which sits far below even our lowest rating.
Every canopy manufacturer publishes a roof-load number. Almost none show you how the number was produced. That gap matters, because a roof rating you can't see tested is a marketing claim — and the rooftop-tent market is full of claims that collapse the first time a real family sleeps on a real roof.
This is how we actually test. It is less glamorous than a spec sheet, and that is exactly the point.
1. What "static" and "dynamic" actually mean
These two words get mixed up constantly, and the mix-up is how buyers get hurt.
- Static load is weight parked on a stationary vehicle: a tent deployed, with people and gear inside. This is the number that matters at camp.
- Dynamic load is weight the roof carries while driving. Aerodynamic forces multiply at highway speed, which is why a roof box or tent is always removed or empty for transit.
Our published figures are static ratings. When you see "500 kg" in our range, it means a stationary canopy carrying a parked load — the camping case. For driving, the rule across our whole range is the same and simpler: carry the tent itself (typically 50–80 kg), nothing more.
2. How the test is run
The test protocol, in plain terms: a production canopy of the specified material and thickness is mounted on its test frame the way it mounts on a truck bed. Load is applied on the roof panel and progressively increased to the target figure, then held while the shell, its mounting points and its door gaps are inspected for deformation.
For our 3.0 mm aluminium alloy canopy, that target is 500 kg — and the full run is filmed. The footage is real and unglamorous: ten grown men standing and jumping on the roof of an orange test canopy, filmed in one take on the factory floor, with the shell holding the load without deformation. The file is in our test-records archive and the clip is being prepared for our YouTube channel, so you can watch it yourself rather than take the number on faith.
What the test proves: the shell, its folds and its mounting points carry the rated static load without structural failure.
What it honestly does not prove: performance over years of vibration, or dynamic behaviour at speed. Those come from conservative engineering margins, not from one test — which is why we publish static numbers instead of inflated "dynamic-looking" ones.
3. Why the rating changes with material and thickness
A roof panel is a beam. Strength scales with material and section, so an honest manufacturer grades the rating instead of publishing one heroic number:
| Shell option | Static roof load |
|---|---|
| Galvanized steel 1.5 mm | 150 kg |
| Aluminium alloy 2.0 mm | 200 kg |
| Aluminium alloy 2.5 mm | 300 kg |
| Aluminium alloy 3.0 mm | 500 kg |
If a supplier quotes one load figure for an entire catalogue — steel and aluminium, thin and thick — they are quoting their best number and letting you assume it applies everywhere. Ask which material and thickness the figure belongs to.
4. How to use the number when you buy
A rooftop tent setup has three loads, and only one of them is the canopy's job:
| Load | Typical size | Whose rating covers it |
|---|---|---|
| Tent, packed, while driving | 50–80 kg | Far under any canopy rating — fine |
| Tent deployed + occupants, parked | 250–400 kg | Canopy static roof load — this is our number |
| Crossbars / rack platform | 30–60 kg | Rack rating: ours is 450 kg static / 250 kg+ dynamic |
Match the middle row to the canopy's static rating with margin to spare, and the setup is sound. A 300 kg static canopy with a typical 2-person tent (occupants plus tent around 300 kg worst case) is at the line — which is exactly why we grade our ratings by material and tell you the real number instead of a rounded-up one.
5. What to demand from any canopy supplier
- The rating in writing, stated as static or dynamic — a number without that word is meaningless.
- The material and thickness the figure was tested on.
- Test evidence. A photo of a test or a filmed run beats any adjective. Ours is filmed; ask us for the link and we send it.
A supplier who cannot produce any of these three is not hiding a trade secret. They are hiding the absence of a test.

FAQ_SPLIT## Frequently Asked Questions
Is 300 kg static enough for a rooftop tent with two people?
A typical 2-person rooftop tent weighs 55–75 kg; two occupants add roughly 150–180 kg. That's around 250 kg worst case — inside our 2.5 mm aluminium rating, with the 1.5 mm steel shell sitting below the line. Check your actual tent weight and choose the shell accordingly; if in doubt, send us the number and we confirm the pairing in writing.
Why don't you publish a dynamic roof load?
Because a dynamic rating depends on driving speed, road surface, mounting geometry and local regulations — a single number would be theatre. The honest rule is simpler: while driving, carry the tent itself and nothing else; the static rating covers camp.
Does the load rating include the roof rack?
No — the canopy rating covers the shell and its mounting points. The rack is rated separately (ours: 450 kg+ static / 250 kg+ dynamic). In a tent setup both ratings apply, and the lower one is your ceiling.
What happens if I overload the roof?
Short answer: you find out at the door gaps first — panels deform, doors start to bind, and seals open. Long answer: overload damage is misuse, outside warranty. Publish-rated setups exist precisely so you never learn this firsthand.
