expanded metal mesh is traditionally seen as a metal material with diamond shaped holes. expanded metal is produced by an expanding machine, which uses a pressured slitting and stretching process to transform solid metal sheets and coils into expanded mesh. The expanded metal company pioneered the process, known as expanding metal, in 1889. Although modern machines are computer programmed and speedier than the original machines the process of expanding remains largely unchanged. Metals can be expanded in a range of material thickness and to a broad choice of patterns to suit specific applications.

Patterns & Shapes - beyond the diamond
In addition to the traditional diamond shaped range of meshes, the expanding metal process can produce a dynamic variety.

Expanded Metal Production
The process for expanding metal was first patented in Hartlepool, UK in the 1880's and despite the amount of time which has elapsed since then, the process remains true to the original idea. Most types of metal, including precious and specially produced metals, can be expanded. Other materials, such as plastics or other ductile materials can also be expanded.
