Colorbond steel almost always outlasts timber and asks for far less upkeep, but timber looks warmer and costs less up front. A straight comparison on lifespan, maintenance, cost and the real question underneath both, the posts and footings.
Timber or Colorbond is the most common fence question we get. Both are good fences. They just suit
different things. Here is the straight comparison on lifespan, upkeep and cost, and the one question
that matters more than the material.
Lifespan and upkeep
Colorbond steel wins on both. It does not warp, it does not rot, and termites cannot touch it. It
never needs painting or oiling. A well-built treated-pine fence lasts about 10 to 15 years before the
palings start to grey, cup and need attention. Hardwood lasts longer than pine, but it still moves and
weathers. Timber is a living material, so it asks for upkeep that steel does not.
Looks and cost
Timber has a warmth that steel does not, and it costs less up front, which is why it is still a
favourite. Colorbond is clean, low-fuss and comes in the full colour range, and it suits a sloping
boundary because the panels rake to follow the ground. Up front, timber is cheaper. Over ten years,
the no-maintenance steel closes the gap.
Choose timber if you want the warm, classic look and you do not mind the upkeep.
Choose Colorbond if you want set-and-forget, no painting, and a clean line on a slope.
The material decides the look and the upkeep. The posts and footings decide whether the fence is still
straight in ten years. That is the real lifespan question, and it is the same for both.
The question under both
Whichever material you pick, the fence lives or dies on the posts. A leaning fence is a post problem,
not a paling or panel problem. We set the posts in concrete to the right depth for the soil and the
height, which is why our 10-year warranty covers the posts and footings on either material.
Ask this, exactly
“Is this genuine Colorbond by BlueScope, with the colour and product named on the quote, or a look-alike steel?”
A genuine quote names the material exactly. 'Steel fencing' with no brand is a flag, because look-alike steel fades and chalks faster than genuine Colorbond.
How we help you choose
Compare both on our estimator to see the price gap for your run and height. Then we talk it through on
the free measure: the exposure, the slope, the neighbour, and what suits your boundary. We will tell
you honestly which one we would put in.
Common questions
Does Colorbond last longer than timber?
Almost always, yes. Colorbond steel does not warp, rot or feed termites, and it never needs painting. A well-built treated-pine fence lasts about 10 to 15 years before the palings need attention. Hardwood lasts longer than pine. Colorbond on concreted posts can outlast both with far less upkeep.
Is timber cheaper than Colorbond?
Up front, usually yes. Treated pine paling is the cheapest material per metre. Colorbond costs a bit more but asks for almost no maintenance, so over the years the gap narrows. The estimator shows you both side by side.
Does Colorbond rust near the coast?
It is built to resist it, and for harsh frontline-coastal sites BlueScope makes a marine-grade product. The detail that matters most is the base: we set the posts in concrete and finish the base so salt and ground moisture do not get a foothold.
