Diamond Grille is the security screen most Queenslanders picture: a tough aluminium diamond grille in a riveted frame, with insect mesh behind it. It has protected homes here for decades because it does the job without costing the earth. You get a real barrier over the window, air and light straight through it, and a look that suits an older home as easily as a new one.
Made and fitted by our own crew, here in Queensland. Measured twice.©
The 7mm aluminium grille is riveted into the frame at close, regular spacing, so the hold is spread right across the screen. There is no single weld to pop and no easy point to lever.
The open diamond pattern lets air and light straight through. Choose a black grille and it recedes as your eye adjusts, so the pattern fades and the view stays.
Diamond Grille gives you a genuine security screen for less than a stainless steel system. That is why it has been the default on Queensland homes for years, and why it is still the right call for plenty of windows.
Riveted, not single-point welded. The hold is spread across the whole screen, so there is no one weak point to attack.
Aluminium, built for the climate. A powder-coated aluminium frame and grille resist corrosion through Queensland summers.
Re-meshable. The insect mesh behind the grille can be replaced down the track without a whole new screen, which stretches the life of the product.
The grille. A 7mm aluminium diamond-pattern grille, the security barrier itself. Its open diamond aperture, roughly 83mm by 69mm, is built for general security, maximum airflow, and a clear visual deterrent at the window.
The frame. Extruded, powder-coated aluminium. The grille is riveted into the frame at close, regular spacing, which is what gives the screen its strength.
The mesh. A flyscreen mesh sits behind the grille. The grille does the securing, the mesh keeps the insects out. You choose the mesh to suit the window (see Mesh Options).
The finish. Standard powder-coat colours, or custom Dulux and Interpon. Grille and frame are usually colour-matched, and a black grille is the pick where the view matters.
Worth knowing before you choose.
It is an aluminium grille, not stainless steel mesh. Diamond Grille is a genuine security barrier, but our Clearshield perforated stainless steel screen is stronger again, and the step up where security is the first priority.
You see the grille. The diamond pattern is visible, more than a fine stainless mesh. A black grille recedes as your eye adjusts and helps a lot, but the pattern is still there. If you would rather not see the screen at all, Clearshield is the one.
It is not a privacy screen. You see out, and from up close someone can see in. Add a privacy mesh behind the grille if privacy matters.
Bushfire rating depends on the mesh. Standard fibreglass mesh is not bushfire rated. Aluminium or stainless steel mesh is required in BAL 12.5 and BAL 19 zones.
Keep it simple to look after. A wash-down with mild detergent and fresh water, no abrasives, and the screen holds up for years.
This is where Measured twice© stops being a slogan. A screen that does not fit is not securing anything. So before anything is made, one of our team comes to the house and works through what matters.
The opening, properly. We take three measurements across every opening and work to the tightest, because the grille has to sit hard against the frame on all sides.
Which windows, and how much of them. On most windows we screen the opening section, the part that can be forced or left open. The fixed pane is screened too where the window’s position calls for it.
How it will fix. Different windows and brands take different methods, worked out at the measure, not on the day.
What it has to comply with. We confirm any BAL bushfire requirement for your address before you commit.
A screen is only as good as the way it is fixed to the house. So we fit each window the way that window needs.
The right method for the window. Depending on the window type and frame, the screen face-fixes to the surround, fits into the channel, or fits inside the reveal. We pick what suits the window, not whatever is quickest.
Fixed so it cannot be defeated. Tamper-resistant fixings into solid structure, with the gap kept tight so there is nothing for a pry bar to grab, and fitted without fouling how the window opens.
Certified, not just installed. The way a security screen is fitted is covered by AS5039.2. We fit to that standard, affix the installation compliance label, and our QBCC licence (No. 732582) stands behind the work.
Then we test it. We check the screen and any access hatch work before we leave.
Diamond Grille is designed and tested to Australian Standard AS5039, the standard for security window grilles. AS5039 puts a screen through knife shear, dynamic impact, jemmy and pull testing, so the rating is earned, not assumed. The way it is fitted is covered by AS5039, and our QBCC licence (No. 732582) stands behind the install.
Allow 10 to 15 working days from the day you approve your measure. Custom colours or BAL-rated mesh can add a little. We will give you a real date, not a vague one.
Not every window is a flat, fixed pane. Awning windows wind out from the bottom. Casement windows swing out on a side hinge, and hopper windows tilt inward. Louvre windows open on a stack of glass blades. Each one still has to open, lock, and work with a security screen in place, so we do not fit every window the same way. We fit the screen to suit the window in front of us, and the security goes on without taking the window’s job away.
These are the most common windows, and both take a standard screen with no special access hardware. What changes is how much of the window we cover, and that comes down to how much of it opens.
One panel slides and the other is fixed, so we screen the opening section, the part that can be forced or left open. The fixed pane is screened as well only where the window’s position calls for it.
Both the top and bottom sash slide, so the whole window opens. We screen the entire window, because either sash could be worked from outside.
An awning window is hinged at the top and winds outward from the bottom, worked by a handle at the sill. That winder has to keep turning with the security screen in place. We fit the screen inside the reveal but above the winder bar, so the screen covers the opening while the handle stays clear underneath. You wind the awning window the way you always have, fully screened.
A louvre window is a stack of glass blades that wind open and pivot out past the face of the window. Fit a screen flat against the opening and the blades foul it as they turn. So we box the screen out, building the frame with depth so it sits proud of the glass. The blades open and close freely behind it, and the airflow a louvre is built for stays exactly as it was.
A casement window is hinged at the side and swings open like a door. A hopper window tilts inward, hinged at either the top or the bottom. Different movements, same problem: the handle, winder and lock sit right where the security screen needs to go, so a flat screen would put the hardware out of reach. We build access into the screen instead, and pick the method that suits the window.
A hinged section of the screen you lift to reach the lock and winder, then drop back into place. It locks shut, and comes in two sizes depending on how far back the hardware sits.
A hinged panel that swings open so you can reach in and work the lock and winder, then closes again. Simple, low-profile access for the hardware behind the screen.
Another advantage of riveting: because the grille is fixed in as its own part rather than fused to the frame, we can run a black grille behind any frame colour. A welded screen is coated as one piece, so the grille is stuck with the frame colour. Riveted, the two are separate, so the frame can match the house and the grille can still be black.
And black is the colour that gets out of the way. The grille is the one part of a diamond screen you actually see, and against a bright outdoor scene the eye reads straight past anything sitting in shadow. So a black grille recedes and you look through to the view, where a light or frame-matched grille catches the daylight and stands out as a lattice in front of it. It is the same reason you see out of a shaded room far better than anyone sees in.
That is why black is our standard, not an upgrade. You keep the frame colour that suits the house, and the grille that secures the window stays out of the way of the view.
On most windows we screen the opening section, because that is where break-ins happen. A burglar goes for the part that opens: the lock gets forced, the sash jemmied, or the window is simply left open. Breaking glass is loud and slow, so it is rarely the way in. Screening the opening section covers the real risk and still lets you open the window for airflow.
We extend the screen across the fixed pane when a window’s position makes a quieter glass entry realistic: a secluded or ground-floor window with fences or planting for cover, or a large pane low enough to climb straight through. Those are the windows worth covering in full.
How the grille is held to the frame decides how the screen behaves under attack, and the two methods fail very differently.
We rivet. The grille is fixed to the frame with rivets at close, regular spacing the whole way around. The hold is shared across many independent fixings, so there is no single join to aim at. An attack has to beat them one after another, and a sudden shock load, which is exactly what a break-in delivers, cannot take them all at once. Each rivet buys time.
Welds do the opposite. They concentrate the hold in a few rigid joints, and they leave a heat-affected zone where the welding has softened the aluminium around the join. A fused joint is brittle by comparison, so under a sharp impact a weld can fail, and the failure can run through the joins beside it.
There is one place this argument is already settled. Aircraft wings are riveted, not welded. That is the highest-stakes load-bearing job there is, carrying constant shock and flex, and rivets are chosen for it for one reason: no single point of failure. If welds were the stronger answer under that kind of load, an aircraft wing is the last place anyone would cut a corner. They are riveted.
Both methods can be built to pass AS5039, so the tested barrier is covered either way. Riveting is the reason ours keeps holding once the test is over and a real attack keeps coming.
The usual knock on riveting is corrosion, from the small bare edges left where the rivet goes in. On aluminium that barely matters: it is not steel, and the metal protects its own surface. A weld that has not been cleaned and prepped properly before powder coat is itself a common place for corrosion to start. So the durability argument does not run the way it is often told.
