Diamond Grille Screens and Doors
Diamond grille screens and doors from Starline Security offer fantastic protection while being one of the most well known and affordable security screen options available. The choice between security and ventilation doesn’t have to be made as diamond grille screens and doors excel in both fields – keeping your home safe, while allowing maximum airflow throughout your home.
Designs
The Diamond Grille inserts are available in two designs. Standard Diamond and Small Diamond. Small diamond has, like the name suggests, a smaller opening.
The size of the small diamond opening is approximately 63 * 57mm (46mm across) and 7.2mm thick making it all but impossible for even small hands to reach through. Small diamond increases the security level. Our Standard Diamond Grille opening is approximately 83mm * 69mm (61mm across) and 7.0mm thick.
*Note: The size of the diamond grille aperture and the thickness can vary slightly depending upon the grille manufacturer and supplier.

Historically, diamond grille was available in many designs including Double Diamond, Triple Diamond, Large Diamond, Tread-Plate Heavy Diamond, a Light Duty 5mm Diamond and other aperture, width and strength specifications.
The introduction and popularity of stainless mesh and perforated products within the Australian security screen and door market since the 1990’s has resulted in a consolidation of diamond grille design offering into the two most popular types: Standard and Small Diamond.
The following are some of diamond grille designs and specifications that are no longer available from Starline Security.







Versatility
Diamond grille screens can be fitted to windows as well as sliding, fixed, and hinged doors. Their size and shape can be customised to suit a variety of configurations, so the aesthetics of your home don’t have to be compromised for a feeling of security.

Colour
We can tailor your purchase of diamond grille screens and doors to work within virtually any colour scheme you wish through our powder-coating process. With almost 200 colours available in both ‘standard’ and ‘custom’ options, there is a perfect solution available for any colour scheme in both the home and office.
Flyscreens
Our diamond grille screens and doors can be fitted with a variety of fly screen mesh options to work with your individual home or business environment. This means if you have pets, want increased visibility, or want better protection against insects, sandflies or the elements, our diamond grille screens can be paired with the appropriate insect mesh to suit your situation.

Security
The safety and wellbeing of our loved ones and belongings matters to all of us, and Starline Security’s diamond grille screens and doors can easily be made to work with highly effective security grade features to enhance their strength. Our best grade of diamond grille has a high-security deep pocket frame, Lockwood triple locks, 4 security pin hinges, 4 wheels, lock guards. Couple this with heavy-duty construction and you can have a formidable security screen or door.
In short, security has no limits with diamond grille screens and doors.
Protection from Falls
Diamond grille window screens are recognised as a fallsafe screen and are compliant with the “Kids don’t Fly” building code, stating that windows that are more than 2m above the ground may be required to be fitted with window restrictors or impact resistant screens. This means that if you live in a multi-storey home, diamond grille screens and doors can be the solution to removing obstructive window restrictors and providing you with the peace of mind that you and your family will be kept safe from any accidents in the top levels.
Given it’s a legal requirement to have your building protected from potential falls, diamond grille screens and doors are a great option for meeting this building code and bringing back your ventilation.

Frequently Asked Questions
Are your Diamond Grille Screens compliant with Australian Standards?
Our security screens and doors are manufactured to comply with Australian Standard AS5039-2008, which sets the benchmark for the design and construction of security screen doors and window grilles. Depending on the configuration and accessories selected, our screens can also meet the rigorous testing requirements, which include impact testing, jemmy testing and knife shear resistance. These standards ensure that the screens not only look good but perform when it really counts, offering peace of mind and practical protection for any home or business.
What are the differences between standard diamond and small diamond designs?
The key difference between standard diamond and small diamond designs simply lie in the size of the grille’s openings. Our standard option features a wider aperture, which allows more airflow and visibility, making it a great allround choice for homes that prioritise ventilation without sacrificing security.
The small diamond version has a tighter configuration, which increases resistance to tampering and intrusion. This design is often preferred in homes with small children or high-security requirements, as it’s much harder to reach through or manipulate. Both designs are crafted from robust 7mm aluminium and provide a sleek, practical finish for any window or door.
Can these screens be colour matched to my home?
We understand that security shouldn’t come at the cost of style, which is why our diamond grille screens and doors can be powder coated in a wide range of colours. With 28 standard colours and close to 300 custom shades available, including the full Colorbond® palette there’s a finish to suit every home or building style, complementing your space without compromise.
Do Diamond Grilles provide insect protection too?
Every diamond grille screen can be fitted with flyscreen mesh to protect your home or business from unwanted pests. We offer several mesh types to suit your environment, whether you're dealing with standard bugs, tiny midges, or energetic pets. Options include pet-resistant mesh for homes with cats and dogs, fine mesh for tropical areas where midges are a concern, and aluminium mesh for added durability. This means you get the benefits of both security and comfort, all in one screen.
Are these screens child-safe or compliant with fall prevention standards?
Our window security screens are fully compliant with the “Kids Don’t Fly” regulations, which require secure window protection for openings located more than 2 metres above ground level. This is particularly important in multi-storey homes, where traditional window restrictors can reduce airflow and limit use.
Can these screens be installed on any type of door or window?
These screens are incredibly versatile and can be custom made to suit just about any door or window configuration. Whether you need screens for hinged doors, sliding doors, fixed windows or bi-fold systems, we can design and manufacture a solution that fits perfectly. We also offer options for double doors and oversized panels and every screen is measured and made to order, ensuring a clean secure fit that works with your existing architecture.
