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.
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 below, 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 below, which is Wire Cloth with .187 wires spaced at 2" on center, the product may be properly specified in either of the following manners:
Center-to-Center Spacing: 2" Mesh, .187 wire
Opening Size: 1.813 clear opening, .187 wire
Wire Cloth is commonly available in the following materials:
CARBON STEELPlain low carbon steel typically ranging from C1006 to C1012 alloy, drawn from rod. Combines strength and weldability with economy.
GALVANIZED BEFORE WOVENCarbon steel coated with a light layer of zinc during the manufacturing process. Adequate corrosion resistance is provided for most indoor applications, but not recommended for outdoor installations.
GALVANIZED AFTER WOVENCarbon steel coated with a heavy layer of zinc after the manufacture of the mesh. Excellent for long term corrosion protection.
HIGH CARBON STEELAbrasion resistant steel used for applications facing significant wear such as media filtering or sorting. Abrasion resistant steel can be difficult to weld, consider mechanical fastening to supporting structure.
STAINLESS STEELCommonly manufactured in 300 series alloys. Type 304 is most popular, but also available in types 309, 310, 316, 321 & 347. Series 400 alloys are also available on special order.
ALUMINUMLightweight and mildly resistant to corrosion, aluminum alloys are readily available. Alloy 1350 is most common and can be easily welded and anodized. Also available are alloys 5056 and 6061.
NICKEL BASED ALLOYSInconel 600, Monel 400, Nichrome V and Hastalloy C276 offer specific characteristics desirable in specialized environments.
SPECIALTY ALLOYSCopper based alloys, bronze, brass and titanium are also available for all woven products. Contact our sales engineers for assistance in selecting the proper specialty alloy for your application.
Weight Per Square Foot
Weight (lbs.) per square foot for square mesh wire cloth can be closely approximated using the following formula where DIAM is the wire diameter in inches and OPNG is the clear opening of the mesh. Common densities are give below.
