316 Marine Grade Stainless Steel Mesh
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.
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.
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.
