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 it’s 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.
