Custom security doors are built to your exact opening, not the nearest catalogue size, so every hinge point, lock strike and grille edge sits flush against your frame. That precision is what actually resists forced entry — gaps and packed-out frames are where standard doors fail. If you want genuine protection that also suits your home’s design, the next step is simple: arrange a measure and a written quote against Australian Standards.
TL;DR:
- Custom security doors are built with millimeter precision, ensuring gaps are minimized to maximize resistance against forced entry.
- Materials like steel, aluminium, and stainless steel mesh offer different levels of strength and corrosion resistance, especially near coastal environments.
- Hardware features such as fixed hinges, three-point locks, and welded fixings significantly improve overall security compared to cheaper alternatives.
- Compliance with AS 5039.1:2023 and AS 5039.2:2024 standards is essential for genuine security performance and simplifies insurance and warranty claims.
- Costs range from about $450 for basic aluminium doors to over $800 for stainless steel options, with lead times typically 10 to 15 business days for manufacturing.

What “custom” means: the measure to install process
A custom security door starts with a site measure, not a showroom pick. A tradesperson checks the opening for square, plumb and any masonry variation, because even a few millimetres of slack lets a door flex under a kick or crowbar strike. From there, the process generally runs in a fixed order.
- Measure — the installer records exact opening dimensions, sill height and any obstructions like architraves or security window screens nearby.
- Design — you choose the door style, infill material, colour and hardware, balancing how much you can see through the door against how much strength you need.
- Manufacture — the door is built to those exact measurements in a factory, not trimmed on site from a stock blank.
- Finish — powder coating or another protective treatment is applied before delivery.
- Install — the finished door is fitted, tested and signed off against the frame.
Millimetre accuracy matters because forced-entry resistance depends on the grille sitting hard against the frame with no leverage points. Decorative laser-cut panels, half-glazed designs and colour matching all add design decisions at step two, and each one can add a few days to your lead time, particularly for powder coat colours outside the standard range.
Materials and infill: what actually stops an intruder
Not every “security” door resists the same kind of attack, and the material you choose changes both the look and the protection level. Independent buyer guidance from Choice notes that steel generally delivers the highest strength, aluminium resists corrosion better, and stainless steel mesh strikes a balance between visibility and durability.
- Steel gives the highest resistance to prying and impact but needs proper corrosion protection, particularly near coastal air, and suits homes prioritising maximum strength over sightlines.
- Aluminium resists rust well and suits most suburban settings, though on its own it’s a lighter-duty option than steel for high-risk locations.
- Stainless steel mesh comes in different grades. 316 grade resists corrosion in coastal and marine environments far better than 304, which is better suited to inland properties.
- Structural-grade aluminium perforated sheet is a newer mid-cost option that can rival mesh performance when specified correctly, without the price tag of full stainless.
- Decorative laser-cut grilles can look striking, but many are decorative overlays rather than the structural barrier — check whether the cut pattern itself carries the load or sits over a separate security layer.
Pro Tip: If you live within a few kilometres of the coast, ask specifically for 316 grade mesh or hot-dip galvanised steel. 304 grade and standard powder-coated steel will corrode noticeably faster in salt air.
Locks, hinges and the construction details that count
The infill material gets most of the attention, but hardware is often where cheaper doors fail first. Industry guidance recommends three-point locking with fixed hinge pins and dog bolts, and welded grille fixings wherever the design allows it.
- A five-pin cylinder lock paired with three-point locking spreads force across the top, middle and bottom of the frame, rather than relying on a single strike plate.
- Hinges should have fixed pins (not removable) plus dog bolts, which stop the door being levered off even if a hinge is attacked.
- Welded grille fixings resist far more force than riveted ones; where riveting is used, fixing density (rivets per linear metre) should be tight, not spaced out to save cost.
- Frame receiver channels need enough depth to hold the door under load, and corners should carry reinforced bracing rather than a simple mitred join.
Ask your supplier to specify each of these on the written quote, not just describe the door as “heavy duty.” A proper frame type matters as much as the door itself.
Which Australian Standards actually matter?
Two standards do the real work here, and both are worth asking about by name. AS 5039.1:2023 sets performance requirements for security door and window screens, testing resistance to forced entry across hinged, sliding, folding and fixed screens. It’s the document that defines whether a product can genuinely be called a security screen rather than a decorative flyscreen.
AS 5039.2:2024, sometimes still referred to as AS5040, covers installation requirements, including face-fitting checks for hinged and sliding doors. A door that passes performance testing but is installed badly still fails in practice.
What to request: a copy of the test certificate referencing AS 5039.1:2023, a signed installation compliance statement referencing AS 5039.2:2024, and written confirmation of the specific hardware used (lock type, hinge type, fixing method).
Suppliers regularly claim standards compliance in marketing material without providing test evidence to back it up, so ask for the paperwork before you sign. These documents also matter beyond peace of mind: insurers increasingly ask for standards references when assessing forced-entry claims, and a documented installation makes warranty disputes far easier to resolve.
What do custom security doors cost, and how long do they take?
Price varies more with material and hardware than with size alone, though non-standard openings do add cost. As a rough guide from Choice’s buyer research, entry-level flyscreen doors that aren’t security-rated start around $250 to $350. Custom aluminium doors that actually meet security standards start from about $450, quality steel doors from roughly $650, and stainless mesh or decorative custom doors from around $800, with recognised brand models costing more again.
- Non-standard openings (unusual heights, angled reveals, heritage door surrounds) require bespoke framing and push the price above a standard-size quote.
- Side panels and sidelights matched to a front door add both material and labour.
- Decorative laser-cut work or custom colour matching adds manufacturing time and often a surcharge over standard powder coat colours.
- Lock upgrades, such as moving from a single-point to a three-point lock, or adding a keyed-alike system across multiple doors, add hardware cost on top of the base door price.
On timing, a typical process runs from a free measure and quote through to factory manufacture in roughly 10 to 15 business days, with professional installation usually taking two to four hours including a final inspection. Custom colours, decorative grilles or supply delays on specific hardware can push that timeline out, so it’s worth asking your supplier for a realistic date range rather than a best-case estimate. For a fuller breakdown by material and door type, Easterndoors’ pricing guide covers current bands in more detail.
What should a proper installation include?
Installation is where a well-specified door either delivers on its standards rating or quietly fails to. A professional install should follow a clear checklist, not a rushed fit.
- Face-fitting check — confirming the door sits flush against the frame with no packing gaps that would flex under force.
- Lock and strike alignment test — every lock point engages cleanly without forcing.
- Gap inspection — checking clearances at the top, bottom and hinge side are within tolerance, since oversized gaps are a common weak point.
- Sign-off — a written compliance note referencing AS 5039.2:2024 and a workmanship check signed by the installer.
Pro Tip: Never accept a verbal assurance that a door “meets standard.” Ask for the signed installation checklist and keep it with your home insurance documents.
Warranty terms differ between suppliers, but most cover manufacturing defects and hardware failure for a set period, while excluding damage from incorrect DIY reinstallation. That’s the main reason to insist on professional installation rather than fitting a custom door yourself: a misaligned frame voids both the performance rating and, often, the warranty itself.
How do you keep a custom door working for decades?
Corrosion protection is the single biggest factor in how long a security door lasts, particularly within a few kilometres of the coast. Powder-coated aluminium needs only occasional washing to stay protected, while hot-dip galvanised steel holds up under harsher conditions and marine-grade stainless mesh is worth the extra cost in salt-heavy air.
- Wash frames and mesh every few months with mild detergent and water to clear salt residue and grit build-up.
- Lubricate hinges and lock mechanisms once or twice a year with a light lock lubricant, not household oil.
- Minor scuffs on powder coat can be touched up with matching paint; anything affecting the lock, hinge or frame alignment needs a technician.
- Inspect the whole door annually, and again after any major storm, checking for movement in the frame fixings.
Why Eastern Security Doors is a straightforward choice for custom work
Eastern Security Doors specialises in custom-made security doors and screens built specifically for residential properties, manufactured in-house rather than trimmed from stock sizes. That in-house manufacturing is what supports a genuinely fast turnaround: detailed consultation and measurement up front, followed by a manufacturing and installation schedule that avoids the long waits common with imported or outsourced products.
Clients consistently point to the workmanship, reliability and competitive pricing behind that process, and every job is backed by a documented installation and warranty rather than a verbal assurance. If you’re weighing up quotes, ask each supplier the same questions this guide has raised: what standard the door is tested to, what hardware it uses, and what paperwork you’ll receive after install. Easterndoors will answer all three in writing before you commit.
When does custom actually make sense?
Custom doors earn their price with non-standard openings, coastal properties needing 316 mesh or galvanised steel, and anyone planning to stay in their home long term, where precise fit reduces mechanical stress and stretches the door’s working life. A perfectly standard opening on a low-risk inland property can sometimes get away with an off-the-shelf security door, provided it’s still tested to AS 5039.1:2023.
My honest view: if your opening isn’t a catalogue size, or you’re weighing decorative style against real forced-entry resistance, don’t compromise on the measure. Book a measured quote and ask for documented standards compliance before you sign anything.
