Security doors provide a practical way to improve airflow, visibility and protection for homes and buildings without compromising comfort. Modern security screen doors are designed to allow fresh air and natural light into a property while helping create a barrier between the home and the outside environment.
​
Unlike traditional solid doors, security screens allow homeowners to leave their main doors open while maintaining ventilation and peace of mind. This makes them particularly popular in Australian homes where natural airflow is important during warmer months.
​
Modern security doors use reinforced aluminium frames combined with high-strength security screen mesh to provide durability and resistance to impact and forced entry. Depending on the system used, security screens may be manufactured using materials such as stainless steel mesh or perforated aluminium mesh systems, each offering different benefits in terms of strength, visibility and privacy.
​
Security doors are commonly installed on:

• front entrances

• sliding patio doors

• balcony doors

• laundry and side access doors

​
At Defendoor, security doors can be customised for a wide range of applications including hinged doors, sliding doors and window screens, allowing homeowners, builders and architects to choose the most suitable solution for their property.

What are Security Screen Doors

 

In Australia, true security screen doors must meet strict performance requirements to ensure they provide reliable protection. The primary standard governing security screens is AS5039, which outlines the structural requirements for security screen doors and window screens.
​
Products designed to meet this standard are typically tested in accordance with AS5041, which defines the testing procedures used to evaluate the strength and durability of security screen systems.
​
During testing, security doors may be subjected to a range of performance assessments designed to simulate common forms of forced entry. These tests can include:
​

• Dynamic impact testing to simulate repeated kicking or forceful impact

• Knife shear testing to ensure the mesh cannot be easily cut

• Pull and probe tests to check the strength of the frame and fixing system

• Jimmy and forced entry tests designed to replicate attempts to lever the door open​

​
Security screen doors that successfully pass these tests are considered capable of withstanding common break-in methods while maintaining structural integrity.
​
Another important component of a compliant security door is the locking system. Security doors require a triple lock system, which secures the door at three separate points along the frame. This distributes pressure across the door frame and significantly increases resistance to forced entry compared with single-point locks.
When combined with a strong frame and high-performance security screen mesh, a triple lock system helps ensure the door functions as a fully integrated security barrier.
​
For homeowners and builders comparing security door options, looking for products tested to Australian Standards with a triple locking system is one of the best ways to ensure the screen door provides genuine security performance.

 

Types of Security Doors

Security doors are available in several configurations depending on the type of opening and how the door operates.
​
Hinged Security Doors
Hinged security doors operate in the same way as traditional entry doors, swinging open and closed on hinges. They are commonly installed on front entrances, side doors and laundry doors where a strong and reliable screen door is required.
Hinged security doors are often considered the most robust option because they use heavy-duty hinges and locking systems designed for high-traffic entry points. Learn more about our hinged security doors.
​
Sliding Security Doors
Sliding security doors are designed for wider openings such as patio doors and glass sliding doors. Instead of swinging open, these doors move horizontally along a track. Sliding security screens allow homeowners to maintain airflow and visibility while securing large door openings. Learn more about our sliding security doors.
​
Security Screens for Windows
Security screens are not limited to doors. Many homes also install window screens to help secure accessible windows while still allowing natural ventilation. Security window screens are commonly used on ground floor windows and other areas where airflow and visibility are important. Learn more about our window screens.
 

 

 

Security Screen Mesh Options

The mesh used in a security screen door is one of the most important factors determining its strength, visibility and durability.

Several mesh types are commonly used in modern security screen systems.

​

Stainless Steel Security Mesh

Stainless steel mesh is one of the most durable materials used in security screens. Marine-grade stainless steel mesh provides excellent strength and corrosion resistance while maintaining clear outward visibility.

This type of mesh is commonly used in high-performance security screens where strength and long-term durability are required.

​

Perforated Aluminium Security Mesh

Perforated aluminium mesh is another popular option for security screens. This material provides strong structural performance while also offering increased privacy compared to traditional mesh systems. Perforated aluminium screens are commonly used in homes where privacy from the street is important.

​

Low-Visibility Aluminium Mesh

Low-visibility aluminium mesh is designed to provide enhanced daytime privacy while maintaining airflow and ventilation. Manufactured from powder-coated aluminium, this mesh helps reduce visibility from outside while still allowing occupants to see out, during light daytime hours.

Security Doors for Australian Homes

Security screen doors have become a common feature in Australian homes because they provide a balance between ventilation and protection. With the ability to customise frame colours, mesh types and door configurations, security screens can be designed to suit both modern and traditional homes.

​

At Defendoor, security doors are custom manufactured to suit a wide range of applications, including hinged doors, sliding doors and window screens.
