Which Security Door Brands Offer the Strongest Protection Against Break-Ins in Australia?
Security screens help prevent break-ins, but not all security doors are built the same. Before you buy, it pays to know what actually separates a genuinely break-in resistant door from one that only looks the part.
What Makes a Security Door “Break-In Resistant”?
When you search for the strongest security doors in Australia, you’ll find plenty of brands making that claim. The honest answer is that “strongest” isn’t a brand name, it’s a set of measurable properties: the mesh, the frame, the locking system and whether the finished product has actually been tested against the Australian Standard for security doors, AS5039.
This guide walks through what to check before you buy, and where Prowler Proof sits against those criteria.

No security door is completely unbreakable, but a well-built one is designed to resist and delay an intruder long enough that they give up and move on. Five things determine how well a door performs under attack:
| AS5039 compliance | Mesh type and thickness | Frame construction | Locking points and hardware | Warranty length |
|---|---|---|---|---|
| This is the Australian Standard covering security screen doors and window grilles. A door tested to AS5039 has been through a set of forced-entry simulations. Ask any brand for their test certificate, not just a claim of compliance. | While it is hard to tell quality mesh from low quality just by looking at it, mesh from quality sources, like Meshtec ensures your screens will pass the tests and last the distance. | his is where a lot of cheaper doors fail. A screwed or riveted frame corner is a weak point an intruder can target with a pry bar. A fully welded frame has no such joint to attack. | More engagement points along the frame make a door harder to force open, and multi-point locking is worth more than a single deadbolt. | A manufacturer’s warranty is a reasonable proxy for how confident they are in their own product’s long-term performance. |
How to Compare Security Door Brands Before You Buy
Use this checklist when you’re comparing quotes or brands:
- Has the door been tested to AS5039, and can the supplier show you the test report?
- What is the mesh made from?
- Are the frame corners welded or mechanically fixed?
- How many locking points does the door have?
- What’s covered under warranty, and for how long?
- Is the installer a certified member of a recognised body such as the National Security Screen Association (NSSA)?
A door that scores well across all six is a genuinely strong option, regardless of brand.
Why Welded Corners and Frame Construction Matter
Most forced-entry attempts target the frame, not the mesh itself. An intruder using a screwdriver or pry bar will look for the weakest joint in the door, which on a lot of security doors is the corner where the frame rails meet.
Prowler Proof doors use fully welded corners rather than screwed or crimped joints, removing that weak point entirely. Our frames are also manufactured with H.I.T. (Hidden Installation Technology), a concealed fixing extrusion that hides and locks away the fasteners used to install the screen, so there’s nothing exposed for an intruder to tamper with or remove.
ForceField®: Built to Exceed AS5039
Our ForceField® range is made using 316 marine-grade stainless steel, the same grade used in marine and coastal applications for its strength and corrosion resistance. Combined with our welded corners and H.I.T. concealed fixings, ForceField® is tested against AS5039 and designed to hold up against both forced-entry attempts and the Australian climate.
Every Prowler Proof security door and screen is manufactured in our automated factory in Banyo, Queensland, and backed by Australia’s only 10 year full replacement warranty. If you’d prefer more privacy with the same welded-frame strength, our Protec range uses a single sheet of perforated aluminium and is a popular choice for coastal homes.
Choosing the Right Security Door for Your Home and Budget
The strongest door on paper isn’t always the right fit for every home or budget. A few things worth weighing up:
- Coastal properties benefit from 316 stainless steel (ForceField®) or all-aluminium construction (Protec) to resist corrosion.
- Character or heritage homes may suit our Heritage range, which uses cast panel designs without compromising on welded-frame construction. Note – Heritage doors are not tested to AS5039.
- Multi-storey homes should also consider Guardian® window screens, which prevent falls while still allowing full window operation. Note – Guardian screens are not tested to AS5039.
- Budget-conscious buyers can look at our Diamond range, which keeps welded-corner construction at a lower price point with custom colour matching.
Whatever range you choose, confirm it’s been tested to AS5039 if you are after compliant security, and ask about warranty terms before signing anything.

Frequently Asked Questions
Stainless steel mesh, particularly 316 marine grade, offers the best combination of cutting resistance and corrosion resistance. Aluminium mesh (as used in our Protec range) is a strong, more affordable alternative, especially for coastal or budget-conscious installs.
AS5039 is the recognised benchmark for security screen doors and window grilles in Australia. Buying a door tested to this standard is the clearest way to verify a manufacturer’s strength claims.
Multi-point locking systems distribute force across several engagement points along the frame, making the door significantly harder to force open than a single-point lock.
Yes. Welded corners remove the mechanical joint that’s typically the weakest point on a security door frame, and are much harder to pry apart than a screwed or riveted corner.
Yes, by having a full replacement warranty, it means you get a whole new screen, not a repair, and you’re not without your security screen, as the switch over occurs all on the same day.
