There are many varieties of weaving patterns of wire mesh, each designed to suit
different applications. The following four examples are common styles of wire mesh
weaving.

Among the above four examples, Plain weave style and
Plain Dutch weave style
mesh are most commonly used as filer media. The following describes how the
mesh size (size of mesh openings) is determined.

[Plain Weave]
With this type of mesh, vertical and horizontal wires intersect at regular intervals
and the individual wire strands are alternately weaved (over/under). This weaving
method (in accordance with JISZ8801 Japanese Industrial Standard) is the most
common weaving pattern. The following calculation is used to determine the size
of the mesh openings for this weaving style.

With this type of mesh, the smaller the mesh (openings), the finer the wire strands
need to be and the weaker the mesh becomes. In such circumstances, it sometimes
becomes necessary to combine the small mesh with a stronger supporting mesh to
assist in its durability.

[Plain Dutch Weave]
This type of mesh is characterized by the horizontal wires which line up and
touch each other. These parallel horizontal wires are intertwined with spaced
vertical wires creating three dimensional openings which are not readily apparent
from simply looking at the surface of the mesh. In order to measure the size
of the openings of this type of mesh,
glass bead test particles are used.
(Results vary depending on the diameter of horizontal and vertical wires used)
Also, due to its construction, this type of mesh is inherently strong and it is therefore possible to make the openings smaller without the need for a supporting mesh for added strength.

*Since the openings of this mesh fall on the same plane, it may be difficult for
this type of mesh to capture elongated contaminants (dust etc.), making this
type of mesh unsuitable for some applications.
|
| The below heat treated mesh is also used for high
durable differential
pressure (like 21 Mpa)
element.
|
[Multilayered
Sintering Wire Mesh]
This type of mesh is created by heat treating several layers of mesh into one
combined mesh. This type of mesh is also very resistant to high pressure and
exhibits uniform mesh openings. This mesh is relatively flat and can be effectively
cleaned (by washing in the opposite direction from normal flow) and reused. |
