Expanded metal is a form of metal stock made by shearing a metal plate in a press, so that the metal stretches, leaving diamond-shaped voids surrounded by interlinked bars of the metal. The most common method of manufacture is to simultaneously slit and stretch the material with one motion. It is often shortened to exmet. "Exmet", however, is a registered trademark in the US for expanded metal produced by Expanded Metal Company, Ltd. It is a large part of the metal industry and plays a key role in metal fabrication.

Expanded Metal is used in:

Architecture

Fencing

Grates

Outdoor furniture (e.g. benches),

Installation of "heating floor" system;

Plastering (metal lath).

Industry (Automotive, Building, Mining etc.)
