Expanded Metal
 SWD
– Nominal dimension – Short Way of Design
LWD – Nominal dimension – Long Way of Design
SWO – Short Way of Opening
LWO – Long Way of Opening
Strands – The sides of the expanded metal design
Strand Thickness – Gauge thickness of metal expanded
Strand Width – Amount of metal fed under dies to produce one
strand
Strand Thickness & Width – Can be varied to create different
openings. The width of the strand should equal or exceed the gauge
of the strand thickness
Standard Expanded Metal – Expanded metal as it comes off the
machine
Flattened Expanded Metal – Flattening Expanded Metal turns the
strands and bonds down to provide a flat surface reducing the
thickness (gauge) and stretching the pattern. These qualities are
important where thickness, and secondary treatments such as
welding and bending are involved.
