Technical Specifications

The construction of security screens requires stainless steel mesh to be attached to an aluminum frame, bringing two different metals together which can lead to corrosion.

To prevent this type of dissimilar metal corrosion, Invisi-Gard have developed and patented a unique clamping system, called Extreme Grip Protection (EGP). This system cleverly captures the mesh within the frame using specially shaped co-extrusions of PVC.

A PVC wedge is then used to apply uniform pressure around the frame which locks in the mesh.

The EGP system, used only by Invisi-Gard, means the mesh is able to be locked into the frame without the uses of screws or mechanical fixing, and means the potentially harmful contact between the metals is avoided.
