About Our Security Doors


Invisi-Gard Security Doors

Stainless steel security screens provide the most effective security in comparison to other screening products on the market.

Stainless steel screen doors have become increasingly popular as they look like a flyscreen, but have the strength of stainless steel. This means that your view is not obscured by crossbars or the like and you can rest assured that these screens have consistently surpassed Australian Standards testing.

Long-Lasting Technology With Invisi-Gard Security Doors

Alpha Screens & Glass uses innovative Clamp technology which ensures that the stainless steel mesh and aluminium frame are firmly secured without coming into contact, preventing galvanic corrosion, which occurs when dissimilar metals contact.

The black powder coating used on these products is designed to resist corrosion which makes it perfect for all applications, indoors and out, as well as cutting down the reflection of light which allows you to see more clearly through it.

Effective Security With Stainless Steel Invisi-Gard Doors

As stainless steel products are top-of-the-range, they are approximately twice the cost of 7mm Diamond Grilles.

In saying this, many people choose to have stainless steel screens installed on the most accessible doors and windows, such as those at the front of the house, and for screening their entertaining areas.

For bedrooms and other rooms in the home, they may opt for 7mm Diamond Grilles to save overall costs.

Diamond Grille Safety Doors

White 7mm Diamond Grille Security Screen installed on the front door in a Sunshine Coast home

Diamond grille safety screens are the classic and most cost-effective way to increase the security of your home.

The strong aluminium grille acts as a visual barrier to deter intruders and are lined with flyscreen mesh (or any other mesh as specified in the flyscreen section) to keep your home insect-free. This thick, heavy-duty aluminium grille provides the basic level of security as well as allowing free airflow, unrestricted vision and low maintenance.

Wide Range Of Colours For Our Diamond Grille Security Doors

Many people no longer like the look of the diamond grille, but their budget may restrict them from buying stainless steel. If this sounds like you, don’t be too worried. Now you have the choice of having a different coloured frame and grille so that your screens have a more modern appearance.

Most of our customers are now choosing to have black grilles fitted to frames which are colour matched to their window frames. Our eyes are said to “see-through” black easier, so a black grilles stand out less than coloured grilles, which is why all flyscreen and other meshes are also made black.

Diamond grilles don’t have to be tacky, instead, they can be given a  modern appearance – adding value to your home.

Frequently Asked Questions

How much is a security screen door?

The amount that you can expect to pay for security screen doors will vary depending on the specific type of door you choose. You can generally expect to pay somewhere in the region of $600 to $1000 for a triple-locked security screen door to be built and installed. Off-the-shelf doors are only considered as barrier doors, as they are not custom made to size and therefore do not pass the test as a security door.

What is the best security screen door?

The best security screen door for you will depend on your preferences. For example, Invisi-Gard uses high visibility 316 stainless steel mesh, meaning sunlight can still get in while you enjoy an extra layer of protection. On the other hand, diamond grille doors give you a much more visible security presence. Whilst this isn’t quite as nice looking as an Invisi-Gard door, it provides a visible deterrent to anyone tempted to break in. Ultimately, which one you choose comes down to your personal style preferences, but both offer excellent safety features.

What is the difference between a Diamond Grille and Invisi-Gard?

The two offer different approaches to home security. A diamond grille is an expertly-built visual barrier made from aluminium but isn’t as pleasing on the eye. Easy to maintain, it also comes with flyscreen mesh to keep insects out and the air flowing in.

On the other hand, Invisi-Gard offers added protection without impacting the overall look of your home. With the strength of stainless steel, you can rest assured these doors meet Australian Standards. What’s more, your view isn’t obstructed by crossbars.

How can I make my front door more secure?  

One of the most reliable ways of making your front door more secure is by fitting a security screen. These sit in front of your front door and offer an extra layer of protection for your home. Now, instead of only having to break through your door, any potential criminals will have to force their way through aluminium mesh or 316 stainless steel too. Most won’t even attempt to break in once they see the screen, and even if they do, it won’t be an easy task.
