This system completely isolates the stainless steel from the aluminium as the mesh is captured by the insulator “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. This in turn applies uniform pressure at all points and locks the mesh into the frame.

Note: there so no metal on metal in this framing it is separated by a patented PVC insulator.
