Expanded Metal

 Termcpi_25inology

SWD- “Short way of diamond, or design” dimension; first number is style designation.
LWD- “Long way of diamond, or design” dimension; not used in style designation.
SWO- “Short way of opening” dimension; used to indicate clear opening in the short direction.
Strand Thickness- Equal to the thickness of the sheet of metal used. The gauge number or decimal thickness is usually the second number in the style designation.
Strand Width- Amount of metal fed under the dies to produce one strand.

Shearing Tolerances

Bond Sheared: Where two strands intersect. Eliminates prongs or jagged edges.
Tolerance: Minus 0 plus 1/2 the design size, either SWD or LWD.
Special bond tolerances on meshes of 1/4” and under.
Random Sheared: This type of shearing leaves prongs or jagged edges. Tolerance: ±1/16”. On grating ±1/8”.
Standard Sheet Sizes: 48” SWD x 96” LWD.
