Diamond Grille Security Doors & Window Screens
Diamond grille security doors are a practical, reliable way to protect your home without sacrificing comfort or airflow. Built with a strong 7mm thick diamond grille and manufactured to meet Australian Security Standard AS 5039, they’re designed to deliver dependable everyday security.
You can choose from a range of screen options including flyscreen, Tuff mesh, and DVA mesh, allowing you to enjoy fresh air and added privacy while keeping insects out. For extra peace of mind, an optional triple locking system is also available, giving you enhanced protection where it matters most.
Every door is custom made and professionally installed to suit your home perfectly, with configurations to match any space including hinged, sliding, stacker, fixed, and grille options.
Finished with a durable powder-coated frame in a wide range of colours and a heavy-duty 75mm profile, these doors are built to look great and last in tough Australian conditions. Backed by a 7-year warranty plus a 1-year workmanship guarantee, diamond grille security doors offer a smart balance of strength, style, and long-term value.
Affordable Home Security
The popularity of the Diamond Grille security door is largely due to its cost-effectiveness. It’s a relatively cheap security door and it’s proven as a home security solution due to its high standards and guarantees.
The best security solution does not have to be the most expensive!
More Security, More Privacy.
One-way or privacy mesh can also be installed into the Diamond Grille security door. One-way mesh is designed to create a bit more privacy. The design makes it difficult to see from the outside; however, it’s easy to see.
