Expanded Metals Terminology

Global Expanded Metals, expanded metal, expanded metal coil, expanded metal cut parts


Expanded Metal: A rigid piece of metal that has been slit and drawn into an open mesh pattern in a single operation. It is stronger, lighter in weight and more rigid than the original base metal. Conventional mesh is formed in a diamond pattern.
Base Metal: Original metal before it is expanded; thickness is usually stated as gauge.
Finished Thickness Thickness of expanded metal after itís final secondary operation(s).
Strand: One side of expanded metal design. (See Diagram)
Bond: The solid intersection of two strands - Double the strand width. (See Diagram)
SWD: Short way of design measured from center of bond to center of bond. (See Diagram)
LWD: Long way of design measured from center of bond to center of bond. (See diagram)
Flattened: Expanded metal that has been cold-rolled after expansion, to provide a smooth, flat, and level sheet. The flattening process usually reduces the original gauge of the base metal.
Unflattened: Expanded metal as it is produced off the expanded metal press with no secondary flattening operation. Material looks similar to a louvered design.
Coil Expanded metal that is produced to a specific width and then wound on a core. Typical footage per coil is 2,000 or more feet.
Cut to length (sheet) Expanded metal that is produced to a specific width and length.
