How strong is our system?
INVISI GARD has been tested and shown to resist more than 50 consecutive impacts, each of 100 Joules of force without failure!
(We have done our own demonstration that shows a screen absorbing a MASSIVE 5 consecutive impacts at 588 JOULES of force EACH!!!)

Our Stainless system not only passes the Australian Standards for the Dynamic Impact test that simulates a forced entry, it absorbed 10 times  the energy required! . It has also passed the Jemmy Test and Knife Test, keep your family, home and valuables safe from crime.

Here a 4kg block of hardwood is fired at 20 meters per second simulating debris in cyclonic storm conditions.

Only quality mesh?
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.

Corrosion resistance.
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. Why is being insulated so important? see this article.
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!
