The process for producing AMIGUARD Security Mesh was first patented in the 1880’s, and despite the amount of time which has elapsed since then, the process remains true to the original idea. Precious and specialty metals can all be expanded, as well as some plastics and other ductile materials.

Sheets or coils of metal are fed into the expanding machine.

Each machine is fitted with a unique “knife,” dedicated to a particular pattern.

The machines can be programmed or manually controlled to ensure the metal is expanded to an exact specification. This unique shearing and stretching process means little waste is created.

The metal is sheared and then stretched in a single process creating the apertures and therefore expanding the metal.
