Aluminium Batten Fence Panels: The Complete 2026 Buyer's Guide (Sizing, Spacing & Install)

Aluminium batten fencing has gone from a designer's specification to the default choice for Australian homes in under a decade — and for good reason. It doesn't rot, doesn't rust through like steel, doesn't need repainting every second summer, and it delivers the clean horizontal-line look that modern facades are built around.

But "just order some panels" is where most projects go sideways. Get the batten spacing wrong and you lose the privacy you paid for. Get the post spacing wrong and you're re-drilling concrete. Get the panel height wrong and your council asks you to take it down.

This guide walks through every decision, in the order you actually need to make it.

What Are Aluminium Batten Fence Panels?

A batten panel is a prefabricated fence section made of horizontal (or occasionally vertical) aluminium slats — the battens — fixed into a rigid perimeter frame. The whole panel drops between two posts and fixes in place.

The alternative is a slat-by-slat build, where individual battens are screwed to rails on site. Panels win on speed and consistency: spacing is set at the factory, so every gap matches, and a two-person crew can hang a run in an afternoon rather than a weekend.

The aluminium itself is almost always powder-coated extruded alloy. That matters more than it sounds — extrusion gives you consistent wall thickness and straight lines, and powder coating is what stands between your fence and a decade of UV.

Why Aluminium Over Timber, Steel or Composite?

Timber looks beautiful for about three years. Then comes the cupping, the splitting, the annual oiling, and eventually the post rot at ground level. In coastal or humid areas, that timeline shortens.

Steel is stronger but heavier, and once the coating is breached at a cut edge or a screw hole, corrosion starts working outward from that point.

Composite is low-maintenance but has more thermal movement, meaning longer runs need more expansion allowance.

Aluminium sits in the sweet spot: light enough for one person to carry a panel, strong enough for a 2.4m span, and naturally corrosion-resistant. It's why it dominates coastal builds from the Gold Coast to Fremantle.

Sizing: Getting the Numbers Right Before You Order

Standard Panel Dimensions

Future Fence batten panels are 2.2m wide, in heights of 900mm, 1200mm, 1500mm and 1800mm. Panels can be cut down on site for shorter sections and returns, so you're not locked to full widths.

Check whether the width you're quoted is the panel itself or the panel-plus-post centre distance. Those are different numbers, and confusing them is the single most common ordering error.

Choosing Your Height

• 900mm — Garden dividers, front yard definition, low decorative runs.
• 1200mm — Front boundaries and courtyards. Keeps sightlines open.
• 1500mm — Pool surrounds and side boundaries where you want definition without a wall.
• 1800mm — The standard boundary and privacy height for most Australian backyards.

Front boundary heights are frequently capped by local council — commonly around 1.2m for the front setback — and pool barriers have their own mandatory requirements. Always confirm with your council before ordering, because a fence that's 300mm too tall is a fence you're taking down.

Post Spacing and Centres

Posts are set at centres, not at gaps. If your panel is 2200mm and your post is 65mm square, your post centres land at roughly 2265mm. Measure and mark centres before you dig a single hole.

For a run that doesn't divide evenly into full panels — and most don't — plan for one cut panel. Put it at the least visible end, or split the difference across both ends for symmetry.

Post choice follows your fixing method: inground posts concreted into the ground, or flanged posts and base plates bolted to an existing slab or deck. All options are in the posts and fixings range. For inground, order posts roughly 600mm longer than your panel height.

Batten or Blade: The Decision That Defines Your Fence

This is the choice people most regret getting wrong. It sets privacy, airflow, light, and the entire visual character of the fence — and unlike height, you can't change your mind after install.

Batten

40mm battens, tightly spaced — browse the full batten panel range. This is the privacy option: it blocks direct sightlines almost entirely, which is what you want on a boundary, along a pool surround, or anywhere a neighbour's window looks in. The tight rhythm also reads as more solid and architectural from the street.

Blade

Side-welded slats at 49mm spacing — see the blade panel range. The wider gap lets natural light and breezes through, giving you an angular privacy effect — largely screened head-on, more open as you move past it. Better where you don't want to wall off a courtyard, or where wind exposure is a concern.

The Rule Nobody Tells You

Privacy is a function of gap size and viewing angle. A gap that reads as fully private square-on from three metres away opens right up when viewed obliquely, or from an elevated position like a neighbour's deck.

If you're screening from a raised viewpoint, go batten. If you're screening from a footpath and want light through, blade will do the job with a lighter feel.

Wind matters too. Tighter spacing means more wind load on the panel, the posts, and the footings. On exposed sites — coastal, hilltop, open paddock — that's an argument for blade, or for deeper footings.

Colour and Finish

Black and charcoal dominate current builds: they recede visually, make gardens look deeper, and pair with almost any facade. If you're weighing the two main options, we've broken the decision down in detail in Natural White vs Black Aluminium Fencing.

Whites and light greys suit Hamptons and coastal styles and show less heat build-up, but they show dust and marks sooner.

Timber-look powder coating gives you a woodgrain finish with none of the maintenance — increasingly popular where a covenant or design guideline calls for a timber appearance.

On finish quality, ask two questions: is the powder coat rated for exterior UV exposure, and what's the warranty term? A coating warranty is the clearest signal of what a supplier actually thinks of their product.

Colour is also the hardest thing to judge from a screen. A colour chip or a profile sample costs a few dollars and settles the question before you commit to a few thousand.

What It Costs

Pricing varies by height, batten profile, spacing and finish, so treat any single figure with suspicion. Budget across four line items:

1. Panels — priced per panel or per lineal metre
2. Posts — one per panel join, plus one to start the run
3. Hardware — brackets, caps, screws, and gate hardware if applicable
4. Footings — concrete, and hire of a post-hole digger if you're doing it yourself

DIY installation typically saves 40–50% of the total project cost. That's real money, but only if you're confident with a string line, a level and a concrete mix. A fence that's out of level reads as out of level forever.

Installation: The Practical Walkthrough

Before You Dig

Confirm your boundary. Not the old fence line — the actual surveyed boundary. Old fences drift, and rebuilding on an inherited error is how neighbour disputes start. If there's any doubt, a surveyor is cheaper than a legal dispute.

Then call the underground services locator before excavating. Every time. Gas, water, electrical and telecom runs are not always where you'd assume.

Have the conversation with your neighbour early if it's a shared boundary. In most Australian states, boundary fencing has cost-sharing provisions — and a five-minute chat up front prevents a six-month headache.

Step 1 — Set Out

Run a string line along the full fence run at the finished height. Mark your post centres along it. Check your total run against your panel count now, while adjustment is still free.

Step 2 — Dig the Footings

As a general guide, footing depth of roughly one-third the above-ground post height is a common starting point, going deeper for taller fences, sandy soil, or exposed windy sites. Confirm the specification against your supplier's engineering guidance — they'll have figures for their exact post section.

Step 3 — Set the Posts

Concrete the posts in, checking plumb on two faces as you go, and confirming each post against the string line for alignment and height. Crown the concrete slightly at the top so water runs away from the post rather than pooling around it.

Let the concrete cure properly before hanging panels. Rushing this is the most common cause of a fence that slowly leans.

Step 4 — Hang the Panels

Panels mount with brackets that sleeve over the 40 x 40mm rear rail. If you want a continuous uninterrupted run from the front, use angle brackets and sit the posts behind the panels instead.

Fix the brackets to the posts at the heights specified, then lift the panel in and fasten. Keep a consistent ground clearance — usually 50–100mm — so you can whipper-snipper underneath and so water doesn't wick up the frame.

Step 5 — Finish

Fit post caps to keep water out of the post cavity. Touch up any coating damage from cutting or handling with matched touch-up paint. Then walk the full run and sight down it — small alignment issues are much easier to fix now than after the garden goes in.

Working on a Slope

Two approaches: stepping, where each panel stays level and drops a fixed amount from the last, creating a staircase profile along the top; or raking, where the panel follows the ground angle. Stepping suits gentle to moderate falls and standard panels. Raking needs panels made for the specific angle, so it has to be specified at order time — measure your fall before you buy.

Maintenance

Wash the fence down with mild soapy water and a soft brush a couple of times a year — more often within a few kilometres of the coast, where salt deposits accelerate coating wear. Avoid abrasive pads and high-pressure washing at close range, both of which damage powder coat.

Check fixings annually and touch up any scratches that reach bare metal. That's the entire maintenance schedule. It's the whole argument for aluminium.

A Note on Pool Fencing

If your fence forms any part of a pool barrier, it is a regulated safety structure, not a design choice. Australian pool barrier requirements govern minimum height, gap dimensions, non-climbable zones, and gate latching and self-closing behaviour — and these are enforced by council inspection.

Confirm compliance requirements with your local council and your supplier before ordering, and have the barrier certified. Standard batten spacing and standard gate hardware will not automatically satisfy pool barrier rules.

Your Pre-Order Checklist

• Total fence run measured, boundary confirmed
• Height selected and checked against council limits
• Batten or Blade chosen for your actual privacy need and viewing angles
• Panel count calculated, cut panel positioned
• Post count confirmed (panels + 1)
• Slope assessed — stepped or raked
• Colour and finish selected, coating warranty confirmed
• Gate positions and hardware decided
• Services located, neighbour consulted

Get those nine right and the install is the easy part. Get them wrong and no amount of good hardware saves the job.
