Introduction of Expanded Metal Mesh
Expanded metal mesh is an intermediate raw material that allows
light and air to flow freely through it and that has more rigidity
than the sheet from which it was produced.
It is formed in an expanded metal mesh press and produced from any
malleable metal sheet product. The plate, sheet, or coil is
simultaneously slit and stretched into diamond-shaped openings.
These openings are of uniform size and regularity.

Styles of Expanded Metal Mesh
Regular (standard or raised) – all expanded metal mesh is produced
in regular form off the expanders. The strands and bonds are set at
a uniform angle to the plane of the sheet. This gives added
strength and rigidity, as well as a skid resistant surface.
Flattened – is manufactured by processing regular expanded metal
mesh in a rolling mill. The rolling process reduces the thickness
of the original base metal.
Strands – The sides of the expanded metal meshdesign v
Strand Thickness – Thickness of the base material from which the
sheet was produced.
Strand Width – Amount of metal fed under dies to produce one strand
Strand Thickness and Width – Can be varied to create different
openings. The width of the strand should equal or exceed the
thickness of the base metal.
SWD – Nominal dimension, Short Way of Diamond v
LWD – Nominal dimension, Long Way of Diamond v
Design Size – Actual dimension SWD and LWD. Measured from a point
to a corresponding point on the adjacent diamond. v
SWO – Short Way of Opening v
LWO – Long Way of Opening v
Bond – Where two strands intersect
