Diamond Grille Security

Familiar look, better built….

Here at Shutterup we are proud to offer you a superb security product. At first glance 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 the one piece. Which is not far from the truth. Prowler Proofs secularist screens are not held together by screws or rivets, they are welded. This adds strength and looks good.

You can choose between the Small Diamond and the Large Diamond Security Grille 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!

Prowler Proof Diamond security screens are available as hinge & sliding doors and window screens, custom-made to your home – with options for mid-rails, solid panels and cross-braces or mullions. We even have a range of pet doors to suit your furry family members.

You have 300 colours to choose from, as well as a range of manufactured options.

At Shutterup Brisbane, we will guide you through the many options and help you make the right decisions for your project.

For optional colour options – there is no extra delivery time and only a small premium on optional colours. See the standard colours, including ColourBond shades on the Dulux Colour Selector Card.

Performance Tests

Dynamic impact test

The Test

The dynamic impact test is designed to simulate an intruder trying to kick his way through a security door or window. The test is performed with a bag full of lead shot and sand, weighing more than 40 kg. The bag is smashed into the security screen with a force of 100 joules – beyond most burglars. The test is repeated 5 times.

The Result

Passed. All four Prowler Proof Diamond designs easily pass the dynamic impact test. Have a look at the video to see just how easily a Prowler Proof Diamond security screen absorbs the impact.

Your Benefit

Kicking your way through a Prowler Proof Diamond design security screen is all but impossible. It handles the Australian Standards test for dynamic impact with ease – the test sample still looks brand new after the test.

Jemmy test

The Test

The jemmy test is designed to simulate an intruder using a lever to get past the security door or window. The test is performed with a large screwdriver at all locking, hinging and fixing points. The force applied is up to 450 N (45 kg) for 20 seconds – way beyond the capability of most potential intruders.

The Result

Passed. The jemmy test is no match for the Prowler Proof Diamond design security doors – all locking and fixing points are secure after the test. The test couldn’t even be performed on the Diamond design security windows – the dynamic impact test left no gap to insert the screwdriver!

Your Benefit

It takes much more than a large screwdriver to get past a Prowler Proof Diamond design security screen. Even with substantial force applied, the locking and fixing points just won’t give way. Back to top Diamond designs jemmy test

Pull test

The Test

Imagine an intruder trying to pull out your security screen…that’s what the pull test is all about. The security door or window must be able to withstand pulling forces of up to 2 kN (200 kg) for 20 seconds at various positions from various angles.

The Result

Passed. It’s virtually impossible to separate the mesh from the welded frame of a Prowler Proof Diamond design security screen. 200 kg is a substantial force – still the screen looks unaffected upon completion of the test.

Your Benefit

A potential intruder will need to pull substantially more than 200 kg at various positions for an extended period of time to have any hope of getting past a Prowler Proof Diamond design security screen. Good luck with that.

Why Choose Diamond Grille Security?

Prowler Proof is the only security screen manufacturer that gives you 50 standard colours and more than 250 optional colours to choose from. So easily match to your existing exterior house colours.

All Prowler Proof Diamond designs have been through the same gruelling security tests – and passed them with ease. All tests have to be passed in succession by the same test sample to get the stamp of approval. A severe challenge for any other security screen…but not for Prowler Proof.

We had Shutterup install a shutter on our kitchen window. Previously we had three other companies tell us that what I wanted could not be done, that the window was too large. One business without even looking at the window. I always explained what I wanted before booking a quote.The Shutterup rep took time to explain how it could be done and an order was placed. The instillation was done as I required and it looks great.The installer took time to sanitize his hands and kept everything tidy.
