About INVISI-GARD - Central Coast Security Screen Doors

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.

Why choose INVISI-GARD?

• 10x the strength of the Australian Standard in terms of absorbed energy.
• Heavy duty extruded aluminium perimeter frame for extra strength.
• The patented EGP retention system ensures the mesh can withstand dynamic impacts. In the testing required to meet AS5041-2008 the screen is subjected to an impact test consisting of a swinging bag weighing 40kg impacting the door five times. This test simulates a door being repeatedly kicked as a burglar attempts to break into your home.
• The 316 Marine Grade Stainless Steel Mesh is extremely difficult to cut.
• The patented EGP retention system means no unsightly screws or other fixings.

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.

The best and most comprehensive warranty in the industry

INVISI-GARD 316 Marine Grade Stainless Steel Mesh is covered by a 10 Year Warranty subject to the conditions on the INVISI-GARD Warranty. You get the assurance of a warranty from ALSPEC, the distributors of INVISI-GARD. ALSPEC is a wholly Australian owned company that has been in the commercial building products business for over 35 years.

The strongest material in its class

Some companies claim that their 0.9mm 304 grade stainless steel mesh is stronger than INVISI-GARD 0.8mm 316 Marine Grade Stainless Steel Mesh because it is thicker.

INVISI-GARD 316 Marine Grade Stainless Steel Mesh gains its strength from the Ultra High Tensile wire (900 MPa) from which it is woven. Even thicker wires can be easily cut if they are "Soft" or of low tensile strength.

ALSPEC have had INVISI-GARD mesh independently tested to Australian Standards and INVISI-GARD 316 Marine Grade Stainless Steel Mesh passes the Australian Standards AS5041-2008 for Knife-Shear.
