What is a security door? A security door is an extra barrier designed with break-in resistant technology to help protect your home.
23 May 2024
What is a Security Door?

A security door is a fortified barrier installed at entry points of a home, designed to prevent unauthorised access and offer increased protection against break-ins. Typically crafted from stronger materials such as aluminium, wrought iron or steel, these doors come equipped with advanced locking systems and are often complemented by reinforced frames and tamper-resistant features.


Security doors should be stronger and more durable than a regular door, but even the existence of a security door can be enough to deter break-ins.

How do security doors work?

The question of how a security door works will have a different answer depending on the brand and technology. Some security doors use a strong glue-like adhesive that dwindles in efficacy over time and ultimately cannot offer adequate peace of mind for home security. My Security Door promises security by utilising 2mm zinc-plated and powder-coated steel plate frames for longevity and durability. We offer the reliable Lockwood 8654 Double Deadlock or Digital Smart Lock systems.


My Security Door is the exclusive provider of a designer Crimsafe range you won’t find anywhere else. Crimsafe technology is the safest on offer in Australia and even exceeds some international safety tests. My Security Door offers customisable designs so you can choose your level of privacy, design and style, airflow, and light exposure without compromising security features.


Understanding how Crimsafe doors work and how Crimsafe technology works will help you make the safest choice for your home. It’s important to be aware of Crimsafe copy models because if it’s not Crimsafe it’s not Crim Safe.

Installation Guide: How to Install a Security Door

Installing a security door is a critical process that enhances its effectiveness:


Choose the Right Fit: We measure your doorway precisely using laser technology to ensure an exact fit—there’s no room for error when it comes to security!

Secure the Frame: Using a licensed professional to secure your frame ensures it’s executed reliably, and it may even reduce your insurance premium!

Install Quality Locks: Use high-grade locks and deadbolts to maximise security. My Security Door and Crimsafe locking systems are the best in the country.

Use a professional: A common mistake is buying a Bunnings Security Door, as Bunnings do not install security doors. Installing your own security door is not advised if you are not a licensed professional.
