"Don't put your valuable assets under a 'budget' dome that wasn't built to survive."
A 12-metre wide container shelter isn't hard to find. What is hard to find is one built with 76 x 2.5mm heavy-wall steel — the same spec we use on every arch of the TS1006 — instead of the 1.8mm tubing most suppliers quietly use to keep the price down.
The TS1206(3m) gives you 72m² of column-free covered workspace across two 20ft containers. Same uncompromising steel. Tighter 1.5m arch spacing. And the same 10-year structural warranty backing it up.
✦ Why 76x2.5mm Steel Outperforms 1.8mm — Full Technical Breakdown →
✔ 76 x 2.5mm Heavy-Wall Steel Throughout At 12 metres wide, the physics of wind leverage are even more demanding than a 10-metre span — so we don't downgrade the steel. Every arch is 76mm OD x 2.5mm wall thickness, hot-dip galvanised.
✔ Tighter 1.5m Arch Spacing The TS1206 uses 5 arch sets at 1.5-metre centres — tighter than many comparable shelters. More arches across the same length means better load distribution and a stiffer overall frame.
✔ 815kg — The Weight That Tells the Story. Our TS1206 ships at 815kg. Comparable 12-metre shelters from budget suppliers come in at 650–750kg. That missing 65–165kg isn't a coincidence — it's the steel that should have been there protecting your assets.
✔ Universal Base Rail System The base rail design means the shelter sits on top of your containers without modification. Secured with 10 Lock-Clamps — no drilling, no welding, no permanent attachment.
✔ Grade 8.8 High-Tensile Bolts Every bolt in the TS1206(3m) is Grade 8.8 — the same industrial-grade hardware used 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 for your machinery and inventory.

The TS1212(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-metre span isn't just a bigger version of a 10-metre shelter. The longer the arch, the greater the bending moment at every connection point under wind load.
Budget suppliers building at this width will often stay on 1.8mm or 2.0mm tube to keep costs down. The frame looks the same from the outside — same 76mm outer diameter — but the wall is thinner, the section modulus is lower, and the resistance to bending is significantly reduced.
We build the TS1206(3m) with 76 x 2.5mm steel because at 12 metres, there's no margin to cut corners.
✔ AS/NZS 1170.2:2021 Certified — Engineered to Australian wind load standards across Wind Regions A.
✔ No-Weld Lock-Clamp Assembly — The entire frame assembles with bolts and clamps. No welding equipment, no trade licence required. Two free spanner kits included.
✔ 10-Year Structural Warranty — We back every TS1206(3m) with our full decade structural warranty. That confidence comes from 20+ years of manufacturing experience and steel we're not embarrassed to show you.
A budget 12-metre dome might save you $500–$800 upfront. But if it fails during a storm — and at 12 metres with thin steel, the risk is real — you're not just replacing a shelter. You're looking at damaged machinery, interrupted operations, and a site safety incident.
The TS1206(3m) is an asset. A cheap dome is an expense waiting to happen.
● Forklift Required — Due to the size and weight of the TS1206(3m) package, a forklift is required for unloading. Please have a minimum 2.5-tonne capacity unit on site.
● No Forklift? — Let us know before dispatch and we can coordinate unloading arrangements.
● Melbourne Warehouse Pickup — Self-collection available. Ensure your vehicle or trailer can handle the package dimensions and weight. Free forklift loading provided.
● DIY-Friendly Kit — The no-weld Lock-Clamp system is designed for site assembly without specialist trades. Two free spanner kits included with every order.
● Professional Installation Available — Optional on-site installation service available within Victoria.

Q: Does the TS1206(3m) cover two 20ft containers side by side?
A: Yes — the 12-metre width is designed to span two standard 20ft containers (GP or HC) placed side by side.
Q: Why does the TS1206(3m) use tighter 1.5m arch spacing instead of 2.0m?
A: A 12-metre span carries more load across a wider roof. The tighter 1.5-metre arch spacing distributes that load more evenly across the frame, improving overall rigidity and reducing stress at individual connection points.
Q: Are end walls available for the TS1206(3m)?
A: The TS1206(3m) is supplied as an open-ended shelter. End walls and roller doors are available as optional extras — see our End Walls & Doors range.
Q: Is the 610gsm PVC cover fire-retardant?
A: Yes. Every TS1206(3m) ships with a heavy-duty 610 g/m² UV-treated PVC cover that is fire-retardant and 100% waterproof.
Q: What's the difference between the TS1206(3m) and the TS1006?
A: The TS1206(3m) is 12 metres wide (vs 10 metres for the TS1006), covers 72m² (vs 60m²), and uses tighter 1.5m arch spacing with additional diagonal end bracing to handle the extra span. Both use the same 76 x 2.5mm steel tube.
