"Don't put your valuable assets under a 'budget' dome that wasn't built to survive."
Two 40ft containers. 144m² of covered workspace. One continuous roof with no centre posts, no gaps, and no compromises on steel.
The TS1212(3m) is the 40ft version of our TS1206(3m) — same 12-metre width, doubled in length, and built to exactly the same steel standard. Every arch is 76 x 2.5mm heavy-wall galvanised steel. Not 1.8mm. Not 2.0mm. The same spec we refuse to budge on regardless of span.
☛ Why 76x2.5mm Steel Outperforms 1.8mm — Full Technical Breakdown →
✔ 76 x 2.5mm Heavy-Wall Steel Throughout Nine arch sets, every one of them 76mm OD x 2.5mm wall thickness, hot-dip galvanised. At 12 metres wide and 12 metres long, this is a serious structure — and we build it with serious steel.
✔ 1355kg — The Weight That Tells the Story Our TS1212(3m) ships at 1,355kg. Comparable 40ft shelters from budget suppliers come in at 1,050–1,200kg. That missing 155–305kg isn't a rounding error — it's the steel that should have been there protecting your assets.
✔ 9 Arch Sets at 1.5m Centres Nine arches at tight 1.5-metre spacing across the full 12-metre length. More arches means better load distribution, less flex in the roof, and a frame that stays rigid under wind load.
✔ Diagonal Bracing on End Bays The first and last arch bays include 12 x 40 x 1.5mm diagonal braces to resist racking — the sideways force that puts the most stress on a large structure when the wind hits hard.
✔ Universal Base Rail + 18 Lock-Clamps Eighteen container clips secure the base rail to your 40ft containers — no drilling, no welding, no permanent modification. The shelter goes on clean and comes off clean.
✔ Grade 8.8 High-Tensile Bolts Throughout Every bolt is Grade 8.8 — the same industrial-grade hardware across our full range. The industry standard is 4.8. Here's why that matters.
✔ 610gsm UV-Rated PVC Cover Heavy-duty, fire-retardant, 100% waterproof. Tensioned and secured with 40 x 1.2mm cover clamp tubes along the full length of the shelter.

The TS1206(3m) is supplied open-ended as standard. Add end walls or doors to fully enclose your shelter:
● 12m Half End Wall — Top half enclosed, bottom half open for forklift and ground-level access
● 12m Door Or Full End Wall — Drive-through access for vehicles and machinery, Or Fully enclosed panel.
● White — In stock (best for heat reflection and UV resistance)
● Silver Grey — Available by pre-order
● Olive Green — Available by pre-order
White is stocked as standard due to its superior performance in Australian conditions.
A 12 x 12 metre shelter isn't just a bigger number. It's 144m² of roof carrying real wind load across a long, wide span — and every metre of that span puts more bending stress on the frame.
Budget suppliers building at this size will trim steel thickness to hit a lower price point. The outer diameter stays at 76mm so it looks the same, but the wall drops to 1.8mm or 2.0mm. The section modulus falls, the resistance to bending drops, and the margin for error in a storm shrinks.
We don't do that. The TS1212(3m) uses 76 x 2.5mm steel because at this scale, cutting corners isn't a business decision — it's a safety decision.
✔ AS/NZS 1170.2:2021 Certified — Engineered to Australian wind load standards across Wind Region A.
✔ No-Weld Lock-Clamp Assembly — The entire frame goes together with bolts and clamps. No welding equipment, no trade licence required. Two free spanner kits included.
✔ 10-Year Structural Warranty — We back every TS1212(3m) with our full decade structural warranty. Twenty-plus years of manufacturing experience behind every weld-free joint.
A cheaper 40ft dome might look fine on day one. But a 144m² structure carrying wind load with undersized steel is a liability — not an asset.
If it fails during a storm, you're not just replacing a shelter. You're looking at damaged vehicles, equipment write-offs, interrupted operations, and a site safety incident that could have been avoided.
The TS1212(3m) costs more than the budget alternatives. It also weighs 155–305kg more. That's not a coincidence — that's the difference between a shelter built to last and one built to a price.

Q: Does the TS1212(3m) cover two 40ft containers side by side? A: Yes — the 12-metre width spans two standard 40ft containers placed side by side, with the 12-metre length running along the containers.
Q: Why does the TS1212(3m) use 9 arch sets at 1.5m spacing? A: A 12-metre long shelter needs consistent load distribution across the full length. Nine arches at 1.5-metre centres gives the frame more contact points to spread the roof load evenly, reducing stress at each individual arch.
Q: Why does the TS1212(3m) weigh so much more than budget alternatives? A: It comes down to steel. Our 76 x 2.5mm tube has significantly more steel per metre than the 1.8mm or 2.0mm tube most budget suppliers use. Across nine full arches on a 12-metre span, that difference adds up fast — and it shows in the 1,355kg shipping weight.
Q: Are end walls available for the TS1212(3m)? A: The TS1212 ships open-ended. End walls and roller doors are available separately — see our End Walls & Doors range.
Q: What's the difference between the TS1212(3m) and the TS1206(3m)? A: Same 12-metre width, same steel spec, same arch spacing. The TS1212(3m) is 12 metres long (vs 6 metres for the TS1206(3m)), covers 144m² (vs 72m²), uses 9 arch sets (vs 5), and mounts with 18 Lock-Clamps (vs 10). It's designed for 40ft containers rather than 20ft.
Q: Is the 610gsm PVC cover fire-retardant? A: Yes. Every TS1212(3m) ships with a heavy-duty 610 g/m² UV-treated PVC cover that is fire-retardant and 100% waterproof.
