01
Welded corners
Every corner is fully welded — stronger than screws or rivets, and it looks like the screen was cut from one piece.

Australian Standard AS 5039
Diamond-grille strength, modern engineering.
The Diamond design passes the AS 5039 security test with ease. The 1,000-hour salt-spray tests (AS 2331) aren’t much challenge either — conducted at +35°C, near-100% humidity, in a solution saltier than sea water. You won’t find a stronger diamond-design security screen on the Australian market.
Test 01
Security (AS 5039-2008)
Six separate tests passed by the same sample: dynamic impact, jemmy, pull, probe, shear and knife shear. Diamond passes with ease.
Test 02
Bushfire
Bushfire-prone zones need corrosion-resistant mesh with openings under 2×2 mm (AS 3959-2009). The fire-attenuation test (FS 4302/3572) shows the reduction in radiant heat flux.
Test 03
Corrosion
AS 2331.3.1 (neutral) and AS 2331.3.2 (acetic acid) salt-spray tests, 1000 hours in an enclosed chamber saltier than sea water. Diamond comes out unphased.
Test 04
Insect protection
The mosquito protection test measures ability to keep mosquitoes out over extended periods. Diamond’s aluminium grille + optional insect gauze passes.
Test 05
Fall prevention
NCC (BCA 2013) requires certain window openings to be screened to prevent child falls. Diamond resists a 250 N outward horizontal action — window restrictors can be removed.
Test 06
Access control
Optional accessories: keying locks alike, pet doors, port holes and hopper hatches. Tested for consistent unassisted access.

We recently had a front security screen door installed by Advanced Security Doors and couldn't be happier with the result. Corey was not only highly professional and knowledgeable, but also one of the friendliest people you could hope to deal with. His genuine, approachable nature made the whole process a pleasure, and his advice helped us choose the perfect product for our home. The installation was smooth and efficient, and the finished door looks fantastic. We wouldn't hesitate to recommend Corey, Jonessa and the team for their exceptional service and quality workmanship.

Corey has been amazing throughout the quotation and install process. With a competitive quote for the product quality, it was installed in under 3 weeks from the initial quote. On the install day, Corey was here for under an hour and even had to grind off some of our molding to enable the door to open. He politely asked and made it look very intentional and part of the initial build. It's changed the aesthetic of the home and allows for so much light into the home, while keeping our loved ones safe. Appreciate it Corey, highly recommend!

Corey was brilliant!! I recently had three security screen doors fitted to my new home. I chose the Prowler Proof doors with Forcefield mesh and they DO look great (the advertising was true - the welded corners look much better than jointed riveted frames). While slightly more expensive than other quotes it really seemed worth it for that difference. As a bonus, Corey was genuinely a pleasure to deal with... Knowledgeable, always friendly and helpful, as well as super fast and efficient when installing the new doors. Besides looking great, the doors also fit perfectly (closers included). I really appreciated his updates on the progress of my order, and the fast turnaround time on manufacturing. I will definitely be ordering more doors in future from Corey (I have two doors on an outbuilding that also need screens). Highly recommended.
