Combining the strength of Marine Grade 316 Stainless Steel with the beauty and flexibility of Aluminium, INVISI-GARD Security Screens offer unparalleled clarity of vision with uncompromised security.
Using the unique, INVISI-GARD Patented EGP Retention Method, you can be assured that the Stainless Steel Mesh will defy the most determined attack from both intruders and corrosion. Tested and approved in accordance with Australian Standard AS5039.2005, you can be assured of having made the right choice when you choose Invisi-gard.
Grade 316 has virtually the same mechanical, physical and fabrication characteristics as 304 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.
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 AS5039-2003 for Knife-Shear.
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.
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 not only adds to the corrosion resistance of the base metal but also cuts down light reflection and refraction thereby increasing visibility through the mesh.
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 the distributors of Invisi-gard, ALSPEC, a wholly Australian owned company that has been in business for over 35 years.
