Invisi-Gard uses grade 316 stainless steel exclusively in its mesh. This grade of stainless steel is commonly called "marine grade" stainless steel and has superior corrosion resistance to other grades of stainless steel such as grade 304. This is because of the steel’s chemistry which includes 2% Molybdenum, an alloying element not found in grade 304. Marine grade 316 offers real value for money, as the product will look pristine for many years to come with a minimum of maintenance.

What is INVISI-GARD mesh made from?


Does INVISI-GARD come with a Warranty?

We are happy to extend a 15 year warranty to all original purchasers of Invisi-Gard as long as the product has been maintained in accordance with the "Care and Maintenance" guidelines. These simply require the product to be cleaned at intervals dependant on your location. For example, if the product is by the coast, the period between cleaning is less than if the product is located inland.


Does INVISI-GARD rust?

If the Care and Maintenance Guidelines are adhered to, Invisi-Gard will maintain a beautiful rust free appearance for the life of the product. Like all other similar stainless steel products though, if it is not maintained, there is potential for corrosion to occur.


The Australian Standard for Buildings in Bushfire Prone Areas refers to the screening of openings with meshes for various Bushfire Attack Levels BAL’s. For sites to BAL-40, the requirement is that the mesh needs to have apertures less than 2mm and be made from a non-corrosive steel. Invisi-Gard mesh has apertures of 1.6mm, and is made of marine grade stainless steel and so is suitable for fire sites up to BAL-40.

What is the fire rating for INVISI-GARD?


Invisi-Gard meets all of the requirements for Security Doors and Windows as determined by Australian Standards, these being AS5039, AS5040 and AS5041.

What standards does INVISI-GARD meet?


How do I maintain my INVISI-GARD screens?

Invisi-Gard requires very minor maintenance. Simply washing the product with a mild detergent and then rinsing off the soap residue from time to time will keep the product looking fantastic for many years and will keep your 15 year warranty valid. The interval between cleaning will depend on your location. For example, if the product is by the coast, the period between cleaning is less than if the product is located inland. When the product is installed, you will receive a set of Care and Maintenance Guidelines which helps to better understand what’s required.
