Quick Answer: Start with fitment (your exact model year, confirmed against 3D scan data), then material and thickness (galvanized 1.5 mm vs aluminium 2.0 / 2.5 / 3.0 mm), then the roof load you actually need, then the factory's evidence for its claims. A canopy that fits wrong or can't show test data is expensive at any price.
Most canopy regret comes from skipping a step. This checklist walks the same order our engineering team uses when we spec a build — fitment first, hardware second, paperwork last.
1. Confirm fitment before anything else
A canopy is not a universal box. Bed rail profiles, cab angles and bed lengths differ by model, generation and market. The checks that matter:
- Your exact model year and cab type — a 2019 Hilux and a 2024 Hilux are different beds.
- Your bed length — measure it; don't assume. Our four-step guide shows how: How to Measure Your Pickup Bed.
- Scan-based fitment — ask whether the supplier builds from 3D scan data of your model year, or shares tooling across models. We scan every platform we sell; tooling is not shared between brands or generations.
If a supplier quotes before asking your model year and market, the quote is a guess.
2. Pick the material and thickness for your use
| Material | Thickness | Static roof load | Best for |
|---|---|---|---|
| Galvanized steel | 1.5 mm | 150 kg | Budget builds, tool storage, no roof tent |
| Aluminium alloy | 2.0 mm | 200 kg | Everyday carry, light camping |
| Aluminium alloy | 2.5 mm | 300 kg | Rooftop tents, heavy overland loads |
| Aluminium alloy | 3.0 mm | on request | Fleet and extreme-duty builds |
Two rules we state plainly on our own product pages: aluminium saves roughly two thirds of the weight of steel, and the roof load scales with thickness — a 300 kg rating belongs to the 2.5 mm build, not to "aluminium" in general.
3. Match the roof rating to your real load
Decide what the roof must carry before comparing prices:
- Rooftop tent + people: you need the static rating to cover the tent plus occupants. A 2.5 mm aluminium canopy at 300 kg static handles most double tents with margin.
- Roof rack plus cargo: our racks rate 450 kg static / 250 kg+ dynamic, independently of the canopy skin.
- Nothing on the roof: galvanized 1.5 mm at 150 kg is honest capacity and costs less.
Whatever number you rely on, ask for the test evidence. Ours is a filmed static load test; we send it on request.
4. Check the hardware that fails first
Canopies rarely fail at the panel — they fail at seals, locks and struts. Ask about:
- Seal life — ours are rated >5 years; ask any supplier for a number, not "long-lasting".
- Lock and hinge spec — anti-theft locks and hydraulic struts should be standard items, not upgrades.
- Corrosion protection — electroplating plus powder coating on hardware, not paint alone.
- Waterproofing process — how is leak-testing done before shipment? (Our test protocol detail is being documented; ask and we'll share the current version.)
5. Understand one-piece vs separate construction
There are two ways to build a hardtop, and the difference shows up in shipping and in year three:
- One-piece (die-formed): no seam between roof and walls to open up, arrives ready to bolt on. Packaging is bulkier, so freight costs more.
- Separate panel builds: roof and walls made separately and joined. Smaller crate and cheaper freight — but the joint is an adhesive seam that can separate and leak over time, and reassembly is needed on arrival.
We build both and will tell you which suits your freight budget and climate.
6. Get the trade terms and warranty stated clearly
Before any deposit:
- Trade terms — EXW, FOB, DAP or DDP. On DDP, customs clearance is the seller's job. Door-to-door delivery covers most countries; we quote Brazil, Mexico, Israel, Iraq, Iran, India and Indonesia we quote EXW only (your forwarder collects at our factory).
- Warranty — ours is 28 months from the day you sign for delivery, plus a 7-day inspection window on arrival and 24-hour response. Any supplier vague on warranty length is telling you something.
- Spare parts — ask what happens in year two if a strut or seal fails, and how fast parts ship.
What to ask any factory (including us)
- Which model year and market is your fitment data for — and can you show the scan?
- What's the static roof load for the exact thickness you're quoting, and is the test filmed?
- One-piece or separate construction — and what's the seam warranty?
- Which trade terms do you actually offer, and which countries are excluded from door-to-door?
- Send the warranty terms in the quote, not after it.

No external data cited. Every company figure in this guide (static load ratings by thickness, seal life, warranty terms, trade terms and exclusions) comes from our maintained fact ledger and internal test records. Prices and lead times are deliberately not quoted here — they are confirmed per build after fitment is checked.
