Aluminium Sliding Doors Prices

Most sliding door pages ask you to fill in a form before they’ll talk about money. We’d rather just show you the prices.

Below is our current price list for aluminium sliding doors across 20 standard sizes – two, three and four panel configurations, in 2100mm and 2400mm heights, with an honest breakdown of what moves the price and how sliding compares to bifold on cost. Comparing across styles? See our full aluminium door prices guide.

Aluminium sliding doors range from $1,580 for a two-panel 1800mm × 2100mm door to $3,560 for a three-panel 3700mm × 2400mm door, including GST. Price depends on panel count, opening width, door height and specification.

Four panel centre opening sliding door prices

Centre opening doors slide from the middle out to both sides, giving you a clear opening in the centre of the span rather than at one end. Useful when the door lines up with a walkway or an outdoor entertaining area.

Opening width Height Price (inc GST) Price (ex GST)
3000mm 2400mm $2,690 – $3,005 $2,445 – $2,734
3600mm 2100mm $2,695 – $3,025 $2,449 – $2,749
3600mm 2400mm $2,900 – $3,300 $2,636 – $3,001

Prices current as of August 2026. Sizes are height (H) × width (W), matching standard Australian window and door convention.

Double glazed sliding door prices

Double glazing adds approximately 30% to the supply price. A few examples, including GST:

  • Two panel 1800mm × 2100mm: $2,050 – $2,335
  • Three panel 3000mm × 2100mm: $3,430 – $3,800
  • Four panel 3600mm × 2400mm: $3,770 – $4,290

Worth it if your doors face a busy road, get harsh western sun, or you’re trying to hold temperature in a room that opens to the outside. For any size not listed, add roughly 30% to the single glazed price above – or ask us for an exact figure.

Sliding vs bifold: which costs less?

If you’re still deciding between the two, sliding doors are the cheaper option by a clear margin – and it’s worth knowing by how much before you commit.

Door type Comparable size From (inc GST) Cost per metre
Sliding, three panel 3000mm × 2100mm $2,635 $879/m
Bifold, three panel 2900mm × 2100mm $3,675 $1,267/m

At a similar span, a sliding door costs roughly $1,000 less than the equivalent bifold – about 30% cheaper per metre. Sliders use simpler hardware, fewer moving parts and less framing.

What you give up is the opening. A three-panel slider opens about a third of the span; a three-panel bifold folds back to open almost all of it. If you want the wall to disappear, pay for the bifold. If you want light, a view and easy access to a deck, a slider does the job for less. See our bifold door price list or French door prices for the full comparison.

What drives sliding door pricing

Panel count

The biggest single factor. At 2100mm high, moving from a two-panel to a three-panel door adds roughly $600-$700 inc GST; a four-panel centre opening configuration adds more again.

More panels means more stiles, more tracks, more rollers and more glass.

Opening width

Within the same panel count, width adds cost steadily – a two-panel door moves from $1,580 at 1800mm to $1,880 at 2700mm, inc GST.

Door height

Going from 2100mm to 2400mm typically adds 8-10%. Taller doors carry more glass weight, which means heavier framing and hardware.

Configuration

A four-panel centre opening door costs more than a three-panel of similar width, because the centre opening arrangement needs additional tracks and hardware.

Glazing

Single glazed as standard; double glazing adds about 30%.

Where sliding doors give the best value per metre

Cost per metre of opening width isn’t consistent across the range. If your opening size is flexible, the wider doors work harder for the money:

Configuration Opening width Cost per metre (from, inc GST)
Two panel 2700mm $697/m
Two panel 2400mm $744/m
Four panel centre opening 3600mm $748/m
Three panel 3600mm $801/m
Three panel 2400mm $1,007/m

The pattern is straightforward: within any panel count, the widest door in that range gives you the most opening per dollar. A narrow three-panel door is the least efficient buy – you’re paying for a third panel across a span a two-panel door would cover.

Installation

Installation is quoted separately from the prices above.

We install across metro Sydney and travel beyond it, and it’s a complete service – we remove your existing door, install the new one, and handle flashing, sealing and making good. You’re not left coordinating a separate builder to finish the job.

Installation cost depends on panel count, site access, the condition of the existing opening, and whether an old door needs removing. Replacing an existing slider in the same opening is usually more straightforward than a new opening in an existing wall.

Buying supply only? That’s fine – plenty of our customers have their own builder or carpenter. We provide fitting guidance and documentation so whoever installs it has what they need.

Standard sizes vs custom sizes

The 20 sizes above are our standard configurations, held in the most common opening dimensions for Sydney homes and renovations.

If your opening doesn’t match – and plenty don’t, particularly in older homes and extensions – we manufacture to size.

Before requesting a custom quote, measure your rough opening: the structural opening width and height, not your existing door. We’ll confirm finished sizes from there.

What’s included, and what’s not

Included: the door, frame, hardware, standard sill and delivery.

Quoted separately:

  • Installation
  • Flyscreens and retractable screens
  • Low-profile or flush threshold upgrades
  • Hardware and handle upgrades
  • Removal and disposal of an existing door

Getting an accurate quote

To give you a firm price rather than a range, we need:

  1. Rough opening dimensions – structural opening width and height
  2. Panel count and configuration – two, three or four panel, and whether you want centre opening
  3. Which way you want it to slide – the fixed and sliding panel arrangement
  4. Glazing – single or double
  5. Finish – standard or dark powder coat
  6. Supply only or supplied and installed
  7. Your suburb – for delivery and install scheduling

 

Compliance

All our aluminium sliding doors are manufactured to AS 2047 – the Australian standard for windows and external glazed doors in buildings – with glazing selected and installed to AS 1288.

If you’re building in an exposed coastal position, on an upper storey, or anywhere with specific wind loading requirements, tell us when you enquire. Wind pressure ratings vary by system and configuration, and we’ll confirm what suits your site rather than assume a standard door will do.

Price isn’t the only comparison. Two doors at the same price can be tested to very different standards. What AS 2047, WERS and NATA testing mean – and the six questions that separate quotes faster than price does.
