Why are some metals more likely to corrode?
When two different metals are in direct contact, the more active metal will corrode first and protect the less active metal. This galvanic phenomenon happens in most security screens.
This is not the case for Invisi-Gard Security Screens for two main reasons:
- The mesh is made of 316 Marine Grade Stainless Steel, which is corrosion resistant due to the naturally occurring chromium-rich oxide film formed on the surface.
- The patented EGP Pressure Retention Method used to isolate the 316 Marine Grade Stainless Steel Mesh from the heavy-duty Aluminium Frame. This method does not rely on screws or other forms of mechanical fixings to minimise the contact between the metals.
