Some Terminology
SWD Short Way of diamond
SWO Short Way of Opening
LWD Long Way of Opening
LWO Long Way of diamond
Flat Expanded metal that is cold-rolled after expansion, to provide a smooth, flat and level sheet. The flattening process will reduce the original thickness by approximately 10%.
Unflat Standard expanded metal with raised diamonds.
Strand Width Width of one strand
Strand Thickness Gauge thickness of strand
Bond Edge Part produced with closed diamonds.
Random Sheared Edge The shearing operation produces an "open" or random edge.
 
 
     
   
     
     
Auxiliary Operations - In-line slitting can be provided holding tolerances as close as ± 005 inch. Circle shearing, edge flattening, bending and powder coat finishing are also available.   Squareness - An expanded metal blank will be square to within the largest tolerance of length or width. (Example) Part size 24" (± 1/32) LWD x 24" (± 1/16) SWD will be square within 1/16".
