STAINLESS STEEL SECURITY 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 are designed to withstand WA’s harsh climate, even in coastal areas.
With so many mesh systems on the market all 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 are not using 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 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 doors and other cheaper options on the market –
Invisi-Gard Security Doors

Invisi-Maxx Security Doors

While offering superior strength and security, the Invisi-Maxx range of doors do 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 doesnt come into contact with the Stainless Steel mesh.
The Salt Spray Test is required by AS5039, security doors and screens have to pass 240 hours in this accelerated weather test with no sign of corrosion.
While some systems start to fail after just 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!
EXTREME GRIP PROTECTION (EGP)
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.
