Stainless Steel Mesh Doors


The Strongest & Most Durable Security Doors on the Market

As an authorised dealer of Invisi-Gard and Invisi-Maxx stainless steel security doors, KNA Security can supply and install super strong and durable doors at unbeatable prices

Manufactured using superior 316 marine grade stainless steel high tensile mesh, our range of stainless steel doors is designed to withstand WA’s harsh climate, even in coastal areas. 

With so many mesh systems claiming to be the best, it can be hard to know what’s best. Many stainless systems in Australia DO NOT meet the requirements set out in the Australian Standards.

Generally, these products do not use High Tensile (900MPa) wire, do not continually check the composition via chemical certification, have inferior and cheap pre-treatments against corrosion before powder-coating, and use lower-grade powder-coats that do not come close to the UV resistance of the powder-coat used in Invisi-Gard systems.

Our stainless steel mesh doors not only pass but significantly exceed all Australian Standards. Check out this demonstration displaying the difference in strength between our modern security screen doors and other cheaper options on the market – 

Invisi-Gard Security Doors

Invisi-Gard sliding and single-hinged stainless steel security doors offer a practical solution to maximise security, visibility and airflow within your home.

With a triple locking system and robust hardware, they are available in 100+ colours and with numerous optional extras, including pet doors, door closers and mid-rails. 

If you’re looking for high-quality stainless steel security doors at affordable prices, look no further than an Invisi-Gard door from KNA Security!

Invisi-Maxx Security Doors

Invisi-Maxx stainless steel mesh doors have forged a reputation as the strongest security doors available. A step up from the Invisi-Gard range, these doors are designed to withstand cyclonic conditions. The 1.2mm mesh option is rated for ‘Region D: Cyclonic Areas‘ with wind speeds up to 324km per hour!

While offering superior strength and security, the Invisi-Maxx range of doors does not compromise on airflow and visibility. With a sleek and modern design, they also have high corrosion resistance and are backed by an impressive 15-year warranty.

Take care when choosing a stainless system; the Invisi-Gard system is fully insulated, meaning the aluminium frame doesn’t come into contact with the Stainless Steel mesh.

AS5039 requires the Salt Spray Test; security doors and screens have to pass 240 hours in this accelerated weather test with no sign of corrosion.

While some systems fail after 500-750 hours, Invisi-Gard has resisted rigorous testing to 2,000 hours. The 316 Marine Grade Stainless used in our system resists 10,000 hours with no sign of corrosion!


Invisi-Gard stainless steel doors are the only option on the market to incorporate the patented EGP retention method. This mesh locks the 316 marine grade stainless steel mesh into the heavy duty extruded aluminium perimeter framing, exceeding the Australian Standard requirements.


Our industry leading range of stainless steel security doors are available in over 100 durable power coated options, as well as a range of timber looks, so we’re sure to have a colour to complement your home.
