After every serious wind event in Townsville, the phone runs hot with the same story: “the Colorbond fence has come down.” It’s frustrating, it’s expensive, and the worst part is that it’s almost always avoidable. Here’s what’s really going on.
It’s not the panels — it’s the structure behind them
Colorbond panels themselves are tough. When a fence blows over, it’s the posts and footings that have failed, not the steel sheets. The panel acts like a sail in high wind, and all that load goes straight into the posts and the concrete holding them. If the posts are spaced too far apart, or the footings are too shallow, the fence simply can’t take it.
The standard-spec trap
Townsville sits in a higher wind region than most of the country. That means a fence here needs to be built to a cyclonic specification — not the standard suburban spec used down south.
The trouble is, a lot of fencing around town is fitted to that standard spec to save time and money: posts too far apart, footings not deep enough, bracketing that isn’t rated for our conditions. It looks fine on a calm day. Then the wet season arrives, the wind picks up, and over it goes.
What a cyclone-rated install actually looks like
Building a Colorbond fence that survives our weather comes down to a few non-negotiables:
- Closer post spacing — more posts sharing the wind load.
- Deeper concrete footings — sized for the height of the fence and our wind region.
- The correct rails and brackets — rated hardware, fixed properly, not just what’s quickest.
- Correct post depth for the soil — Townsville’s clay and rock both need the right approach.
None of this is exotic. It’s just doing it properly — and it’s the difference between a fence that lasts and one you’re replacing after the next blow.
Replacing a fence that’s already gone?
If your fence has come down, it’s the perfect time to fix the underlying problem rather than rebuild the same weakness. When we replace storm-damaged fencing we re-engineer the post spacing and footings so the new fence is genuinely rated for where you live. We can also handle the insurance-style clean-up and removal with our own machinery and tipper trailers.
It’s worth knowing this applies to timber too — the same principles keep a timber fence standing.
The bottom line
A Colorbond fence that blows over isn’t bad luck — it’s usually an install that was never rated for Townsville in the first place. Build it to the correct wind-region spec and it’ll shrug off the weather for years.
