Prowler Proof’s Diamond Designs look similar to other Security Screens, but have a closer look...

You’ll soon notice that there are no visible joints – it looks and feels like the security screen is made in one piece. Which is not far from the truth. Prowler Proof’s security screens are not held together by screws or rivets, they are welded. This adds strength…and good looks.

You can choose between the Small Diamond and the Large Diamond designs. Both are secure and economical - Small Diamond marginally more secure, Large Diamond marginally more economical. Both options are available as SnapLock - a unique production process that makes it possible to choose any colour frame to match a black mesh. Looks fantastic!

10 year replacement warranty

All Prowler Proof product is covered by our 10 year replacement warranty. It's Australia's only screen replacement warranty and means you will get a brand new product if something goes wrong with your screen.

screen transparency

Good Transparency

While the grille partially obstructs your view, airflow is still high and allows the breeze in for ventilation.

screen welded corners

Welded Corners

All Prowler Proof products feature fully welded frame corners. A weld can be stronger than parts joined by a screw or rivet. It looks better too. The weld means the screen looks like it's made in one piece. You will immediately notice the difference when you compare Prowler Proof with a product that is held together by screws or rivets.

aluminium grille

Aluminium Grille

The Diamond range provides several options of the traditional grille pattern for an economical security alternative.

qualicoat powdercoat

Qualicoat Accredited Powder Coating

Prowler Proof is one of only 10 powder coating applicators in Australia to be approved by Qualicoat International. Qualicoat is an international benchmark of quality. Qualicoat International audits Prowler Proof’s powder coating line twice a year, to allow us to retain our certification. The powder coating is a key element in the appearance of a security screen. The long term benefit of choosing a Qualicoat certified screen is superior corrosion protection – as evidenced in the fact that Prowler Proof is the only security screen to pass the acetic acid salt spray test and the only manufacturer to offer a 10 year replacement warranty.

Australian Standards Testing

All designs have been put through the Australian Standards Security Test (AS 5039) and passed with ease. The 1,000 hour salt spray tests (AS 2331) are no match either. Even though they take place in an enclosed chamber at +35º C and almost 100% humidity with a solution saltier than sea water. You won't find a stronger diamond design security screen on the Australian market.

security test


The Australian Standards (AS 5039-2008) test consists of six separate tests that all have to be passed by the same test sample. The tests include dynamic impact test, jemmy test, pull test, probe test, shear test and knife shear test.

bushfire test


Bushfire prone zones require that openable windows must be screened with corrosion-resistant steel, bronze or aluminium mesh with an opening of less than 2 mm x 2 mm (AS 3959-2009). The fire attenuation test (FS 4302/3572) shows the reduction in radiant heat flux level provided by the screen.

corrosion test


Whenever two different metals interact there is a risk of corrosion. The tests (AS 2331.3.2 and AS 2331.3.1) to show corrosion-resistance are the acetic acid salt spray test and neutral salt spray test.

insect protection test

Insect Protection

The mosquito protection test tests a screens ability to keep mosquitoes out over an extended period of time.

access control test

Access Control

Allow unassisted access for pets or people, through the addition of optional access control accessories.

fall prevention test

Fall Prevention

The National Construction Code (NCC) (BCA 2013) requires that window openings be either restricted or screened, in certain circumstances, to prevent children falling. Screens that resist an outward horizontal action of 250 N meet the code and mean that window restrictors, that prevent the window being open more than 125mm, can be removed.
