INVISI-GARD is Australia's premier security screen brand because it's made from the toughest material in its class AND features unique patented product architecture. The COMBINATION of these two vital features provides the maximum protection for your family and your home.
At the heart of every INVISI-GARD security screen and security door is our high tensile 316 marine grade stainless steel mesh. The grade 316 mesh used in INVISI-GARD sets the world standard in terms of its quality, precision and longevity.
This class leading mesh is retained in an aluminium frame using our patented EGP (Extreme Grip Protection) retention system. This unique design ensures maximum strength and durability through an assembly technique that avoids contact between the two dissimilar metals - a major cause of corrosion over time.
INVISI-GARD is designed first and foremost to protect your family and home from would-be intruders and performs this task better than any other product on the market.
It also protects your home from flying insects and maintains your view.
INVISI-GARD security doors and screens are without question the best investment for your family's safety. They are also the best investment for the look and value of your home.
EGP (Extreme Grip Protection) Retention System
Only INVISI-GARD Stainless Steel Security Products incorporate the Patented EGP (Extreme Grip Protection) Retention Method which locks the 316 Marine Grade Stainless Steel Mesh into the Heavy Duty Extruded Aluminium perimeter framing.
The EGP Retention Method completely isolates the Stainless Steel from the Aluminium as the mesh is captured between the Insulator (an "L" shaped co-extrusion) and the Keeper (a straight, ribbed co-extrusion). A rigid PVC Wedge is driven into the receiver channel around the full perimeter of the screen applying uniform pressure at all points and locking the mesh into the frame.
This innovative configuration grips the 316 Marine Grade Stainless Steel Mesh so well that it easily passes the Australian Standards requirements for security screens and doors AS5039-2008.
INVISI-GARD Stainless Steel Security Products do not require screws or any other form of mechanical fixing to secure the mesh to the perimeter frame. As a result the potential for corrosion through dissimilar metals contact is avoided.
INVISI-GARD 316 Marine Grade Stainless Steel Mesh
The most corrosion-resistant material in its class
316 Grade has virtually the same mechanical, physical and fabrication characteristics as 304 grade, but with better corrosion resistance, particularly to pitting corrosion. There are some key differences between the two grades of stainless steel that pose both benefits and shortcomings depending on which grade you choose. Due to these differences in chemical composition 304 Stainless Steel is not as corrosion resistant as 316 Stainless Steel. "Tea Staining" and surface pitting or corrosion, are potential problems with 304 grade stainless steel but pose less of a threat to products manufactured from 316 grade stainless steel.
Why doesn't INVISI-GARD 316 Grade Stainless Steel Mesh cut like so many others?
The difference is in the tensile strength of the wire used to weave the mesh. As the wire used in the INVISI-GARD mesh is of such high tensile strength, the weaving process is made more difficult. The mesh is much harder to keep flat and straight and requires specialised weaving equipment and techniques to achieve the quality and flatness that is a hallmark of INVISI-GARD mesh. This explains why many cheap imported meshes either pass the knife-shear test but fail on weave quality and flatness, or pass on weave quality and flatness but can be cut like butter.
Premium powder coating improves aesthetics and optical clarity
The powder coat finish on INVISI-GARD has been specially developed to ensure great looks, clear vision and long life. INVISI-GARD 316 Marine Grade Stainless Steel Mesh is coated with a black polyester powder coat finish. This coating cuts down light reflection allowing clear visibility and is suitable for outdoor applications. Some competing systems use hybrid epoxy powder coatings which are completely unsuitable to outdoor environments leading to reduced product longevity.
