WIRE CLOTH WITH MESH SIZES LESS THAN ONE INCH CAN BE CLEARLY SPECIFIED IN ONE OF THREE WAYS:
Center-to-Center Spacing: measuring the mesh from the center of one wire to the center of the next adjacent wire.
Opening Size: Measuring the clear opening between the wires.
Mesh Count: Measuring the number of openings in the mesh per lineal inch of material, expressed as a count.

For the material at right, which is a Wire Cloth with .080 wires spaced at 1/4" on center, the product may be specified in any of the following manners:
*Center-to-Center Spacing: 1/4" mesh, center-to-center, .080 wire*
*Opening Size" .170 clear opening, .080 wire*
*Mesh Count: 4 Mesh, .080 wire*

WIRE CLOTH WITH MESH SIZES EQUAL TO OR GREATER THAN ONE INCH MUST BE SPECIFIED IN ONE OF TWO WAYS:
*Center-to-Center Spacing: Measuring the mesh from the center of one wire to the center of the next adjacent wire.*
*Opening Size: Measuring the clear openings between the wires.*
For the material to the right, which is Wire Cloth with .187 wires spaced at 2" on center, the product may be properly specified in either if the following manners:
*Center-to-Center Spacing: 2" Mesh, .187 wire*
*Opening Size: 1.810 clear opening, .187 wire*

WIRE SIZE DIAMETERS

NOTE: WHEN ORDERING WIRE CLOTH, IT IS PREFERABLE TO STATE THE EXACT WIRE DIAMETER IN DECIMAL FRACTIONS OF AN INCH RATHER THAN WIRE GAUGE NUMBERS. CONFUSION BETWEEN STEEL WIRE GAUGE NUMBERS AND NON-FERROUS GAUGE NUMBERS CAN OFTEN LEAD TO IMPROPER OPENINGS BEING SPECIFIED.

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:

(MESH SPACING - WIRE DIAM)² x 100 = % OPEN AREA

(MESH SPACING)²

EXAMPLE: To find the open area for square mesh wire cloth using 1/2" mesh, .120 wire:

(.500 - .120)² x 100 = 57.8 % OPEN AREA

(.500)²

WIRE MESH SPACINGS

Woven and Welded Wire Cloth are identified and manufactured based upon their mesh sizes (wire spacings). These mesh sizes are expressed in either center-to-center wire spacings, clear opening between the wires, or mesh count.
