Bolting Cloth: Made from light wire diameter woven into a plain square mesh pattern. The light wire diameter provides a high percentage of open area. Bolting cloth is principally used in sifting and screen printing; however, its relatively high percentage of open area makes it desirable in many other applications.
Calendering: A process that rolls wire cloth to make its surface smoother by flattening the intersections of the wires. It involves passing the wire cloth through rollers to reduce thickness or create a smooth finish. This process is also known as rolling.
Crimp: Undulations in warp and fill wires which hold each other in place.
Edge Finish: typically designated for a wire mesh if its not a raw edge.
Fill Wire: aka SHUTE WIRE, wire running across the width of the cloth.
Hardware Cloth: Plain weave square mesh cloth of relatively light wire galvanized after weaving (usually between 2 to 8 openings per lineal inch).
Inter Crimp Wire Cloth:
Woven wire cloth with an extra crimp in both warp and fill wire. Both the warp and shute wires are crimped with extra crimps or corrugations between the points of intersection. This technique is usually required when weaving large openings with fine wires.
Galvazing Wire Cloth:
An inexpensive method of zinc coating to prevent corrosion and rust of steel wire mesh. Galvanized steel wire, also known as galvanized iron wire, finds most uses in binding of construction materials or weaving of galvanized wire mesh products.
Market Grade: Applies to wire cloth specifications most commonly used for general work. Market grade cloth is made of one size wire for each size closed mesh. The specifications covers everything from a 1/2″ opening down to 20 microns.
Mesh Count: Number of openings per lineal inch, measured from center of wire to center of the wire.
Micronic Filter Cloth: Wire cloth of fine wires usually giving a particle retention of 50 microns or less. The micronic filter cloth is used for the separation of solids and clear liquid filtration as in the cleaning of fuels or hydraulic liquids, or in water treatment.
Pitch: The sum of the aperture or opening size and the wire’s diameter or gauge size.
Raw Edge: A mesh with exposed weft wires which are a result of a rapier (shutterless) loom. Finished edges can be achieved by tucking or looping the weft wires to achieve a finished edge.
Rectangular Mesh: Wire cloth with different warp and fill wire mesh counts which results in rectangular openings. The most common have a higher warp mesh than filler mesh. Advantages are increased open area and reduced cost.
Selvage Edge: or looped edge, the finished edges of wire cloth running the length of the roll which are produced by the weaving operation.
Shute: Wires running across the width of the cloth as woven.
Space Cloth: Wire cloth specified by the opening size rather than by the mesh count.
Tucked Edge: The exposed weft wire being tucked back around the edge warp wires so that the end of the weft wire is no longer exposed.
Warp Wire: The wire running parallel to direction of the wire mesh length or its roll length.
Weave Types: Pattern in which wires are interwoven.
Weft Wire: or Shute Wire, runs parallel to the width of the wire mesh or the roll’s width.
Welded Wire Cloth: Warp and fill wires lay flat, no crimp; and are welded at each intersection
