About Wire Cloth
Wire cloths are materials that are typically woven
into a grid pattern with various opening and wire diameters but can also
be fashioned from welded wire metal. Wire cloth diameters for industrial
wire cloth could be from .0008 inches to greater than one inch. Wire
cloth manufacturers make products that consist of a wide range of design
specifications with various types of materials and weave styles. The
application determines the best choice of material, which includes brass,
copper, steel and stainless steel, aluminum, bronze, titanium, molybdenum
and tungsten. The weave is the pattern resulting from the manner in which
the wires cross each other vertically and horizontally. Horizontal, or
lengthwise, wires are warp wires, and vertical, or crosswise, wires are
shute wires. Metal fabric can assume many shapes to accommodate specific
needs.
Wire cloths, or mesh, are classified according to weave types, wire cloth
manufacturers commonly produce plain square, twill square, plain Dutch
and twill Dutch. Plain square wire cloths have the same diameter shute
and warp wires woven in a simple alternating over and under pattern,
producing screens and meshes with an equal mesh count in both directions.
The staggered pattern of twill square mesh provides fine filtration and
supports larger loads than the plain square weave. In plain Dutch weave,
a high-density weave, the warp wires are larger in diameter and heavier
than the shute wires, allowing for very high particle retention and low
flow rates. The twill Dutch weave produces a coarse mesh in one direction
and a fine mesh in the other, producing wire cloth that is ideal for
filtration of heavy material.
There are several advantages to using metal wire mesh. It is easy to
manipulate into the required shape. Due to its strength and high temperature
resistance, it has extended serviceability. When wire cloth is used as
a filter, there is no deterioration during filtration, and it is non-polluting.
Wire cloth is also easy to clean and maintain. One of the most common
uses for wire cloth is as a filtration media. It is also ideal for strainers.
Other applications include spark and flame arrestors, screen printing,
protection for other filter media and medical implants.
When selecting a mesh, the mesh count is the most important thing to
keep in mind. The mesh count is the open area between wires and can be
expressed as a whole number, a fraction or as two numbers. A whole number
and fractions indicate the distance between the centers of both horizontal
and vertical parallel wires. Two numbers such as 30 x 30 indicate the
actual number of openings per linear inch, both vertically and horizontally.
Other common specifications for wire cloths include material, weave and
wire diameter. Wire cloth manufacturers determine whether to use metal
or alloy according to the application requirements, such as resistance
to corrosion, heat, abrasion and vibration.

Types of Wire Cloth
-
is wire cloth or mesh that supports the surface of a screen.
-
is a stainless steel mesh with a plain weave construction and a small
wire diameter, resulting in a high percentage of open area.
-
are baskets formed from wire cloth and may have a round or rectangular
frame and be constructed from rod, flat or angle stock. Cloth baskets
used for small parts may have a heavy screen outer lining for protection
and strength.
-
may be used for Faraday cages, electromagnetic shielding, papermaking
and insect screens. Copper mesh is quite ductile and has very little
springback after being bent or formed.
-
is cloth with differing wire diameters designed for the express purpose
of filtering or straining. Filter cloth is woven in both plain and twill
patterns with a higher number of wires in one direction.
- is a mesh material.
- are implements with mesh baskets that are used for straining.
-
is woven with uniform mesh count and wire diameter in either direction.
- are used for sifting, especially in food service and plumbing applications where its corrosion-resistant quality is needed.
- is the most common material and has high strength and corrosion
resistant properties. The mesh pattern consists of square openings.
-
come in a wide variety of styles, including half-height, microplate,
wet washing, extra depth, air jet and grain sieves. Test sieves are
totally sealed and have precision frames, structured rims and evenly
tensioned mesh.
- is a material made of parallel and perpendicular interlocking metal wires.
