Expanded metal is a multipurpose material that is produced from solid sheets or plates of carbon steel, galvanized steel, stainless steel or aluminum. It is available in four basic types: standard, flattened, grating, and architectural meshes. Expanded metal is often used in fencing, walkways, grating, and security screens.

Standard/Raised Expanded Metal – This features diamond-shaped openings which are created by stretching the sheet metal. It is ideal for fencing, walkways, and protective barriers.

Flattened Expanded Metal – This type of metal undergoes an additional process where the raised strands are cold-rolled. This creates a smooth, flat surface and a more uniform appearance. It is suitable for architectural uses, like panels, grilles, and filtration systems.
