The Poly Advantage

Poly vs Steel
Poly Wins

TTi poly tanks weigh less, carry more, never rust and come with a 25-year warranty — while steel keeps costing you in maintenance, downtime and lost payload. Here's why Australia's serious operators choose poly.

The Poly Advantage

Poly vs Steel

Lighter Tare, More Payload

Poly tanks weigh significantly less than steel — more legal payload every run, fewer trips, lower fuel burn.

25-Year Tank Warranty

The industry's strongest warranty. Zero reported tank failures in over 25 years of poly manufacturing.

Rustproof & Corrosion-Resistant

Poly never rusts. No liners to fail, no coatings to chip — even carting saline, recycled or bore water.

Virtually Maintenance-Free

No painting, no rust treatment, no panel beating. Poly keeps your fleet on the road and out of the workshop.

UV-Stabilised & Impact-Resistant

Purpose-built UV-stabilised polyethylene that flexes on impact instead of denting or cracking.

Shadforth Civil — Case Study

How Shadforth Civil cut downtime & costs switching to TTi

When a water truck goes down, we have to stop a lot of works. The downtime has been a huge game changer — saving us so much time in repairs and maintenance. We get less breakdowns, less downtime. We can generate more revenue because people are actually working and not sitting around waiting for machines.
