Expanded Metals Terminology
|
|
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.
|
|
Cut to length (sheet) |
|
Expanded metal that is produced to a specific width and length.
