Invisi-Gard Stainless Steel Security Doors & Window Screens
As an authorised installer of Invisi-Gard stainless steel security doors, we deliver premium protection designed to withstand Australia’s toughest conditions while maintaining clear views and natural airflow.
Built with marine-grade stainless steel mesh and precision-engineered framing, Invisi-Gard systems are trusted for their strength, durability, and clean architectural finish. Installed with care and attention to detail, every door is fitted to perform seamlessly, giving you peace of mind, everyday security, and a finish that genuinely enhances your home rather than detracting from it.
Strength & Durability from Marine-Grade Stainless Steel
Designed and tested to perform in harsh West Australian conditions, our security doors exceed all Australian Standards for security doors, giving homeowners confidence that their property is properly protected.
The fine stainless steel mesh is not only incredibly difficult to cut or penetrate, but it also maintains clear visibility and airflow, proving that high-level security doesn’t have to come at the expense of comfort or design.
Colour Range
Available in hundreds of durable powder-coated colour options, you can match or contrast your existing frames with ease. For a more natural aesthetic, there are also a range of realistic timber-look finishes, giving you the warmth of wood without the maintenance. It’s security that doesn’t force you to compromise on design. Here are some of the most popular options:
Door & Window Configurations
Invisi-Gard doors and window screens are available in a wide range of configurations to suit different openings and applications, including sliding, hinged (single), and French door options, along with various custom features and hardware choices.
