WIRE MESH SPECIFICATION
HOW TO ORDER/SPECIFY:
CONSTRUCTION - Woven or Welded (For woven products, identify crimp style).
MATERIAL - Indicate material such as plain carbon steel, stainless steel or other alloy.
WIRE DIAMETER - In decimal, thousands of one inch.
WIRE SPACING - Specify square, rectangular or specialty configuration with wire spacing center-to-center, clear opening or mesh count.
SIZES - Indicate sheet or roll width and length, or width and length of cut-to-size pieces.
NOMENCLATURE:
CALENDARED WIRE CLOTH - wire cloth that has been passed through heavy rollers to reduce the thickness of the material or flatten the wire intersections to produce a smooth surface.
CLEAR OPENING - the space between adjacent parallel wires.
CRIMPS - corrugations placed in the wire which allow the wires to be woven together. The placement and style of the crimps determine the location of the intersections and permit tight locking of the wires.
FILL WIRES - wires running across the width or short way of the material as woven. (Also referred to as shute or cross wires.)
GAUGE - a measure of wire diameter commonly used by manufacturers. To avoid confusion between ferrous and non-ferrous gauge dimensions, always specify your desired wire diameter in decimal inches.
HARDWARE CLOTH - square mesh cloth, galvanized after assembly and available in either woven or welded construction.
MESH - the number of openings in a lineal inch measured from the center of one wire to a point one inch distant.
OPEN AREA - the proportion of open space as a percentage of the total material area.
SELVAGE - a finished edge used to prevent fraying or unraveling of woven wire cloth.
WARP WIRES - wires running parallel to the length or long way of the material as woven.
PERCENTAGE OF OPEN AREA:
Open area, expressed as a percentage, is the ratio of clear area to screen area for a specific wire cloth. This ratio is useful for comparing how readily various materials or elements will flow through the cloth.
To calculate the open area of square mesh wire cloth, use the following formula:
