Measuring Wire Cloth

Wire cloth comes in two variants: woven wire cloth and welded wire cloth. Woven wire cloth is the most common. It is used for general sorting, screening, and filtering applications. Welded wire fabric usually has a smoother surface and normally has a larger open area. The strength and rigidity of the welds are designed to maintain a uniform cloth.

There are several things to take note of when measuring wire cloth. The technique you use when measuring the cloth will depend on the mesh. When you are counting mesh, the mesh count can either be a whole number, a fraction or shown as two numbers. To measure wire cloth, no matter the style, the mesh count needs to be taken in both directions.

Coarse mesh includes the following: mesh wire, woven wire mesh, and wire mesh basket. To take measurements in both directions in this type of cloth, you will count the amount of openings per linear inch covering from wire center to wire center. Once you've recorded the first number, you should take a second count at a 90-degree angle to the first one.

Finer types of mesh are woven wire cloth, stainless steel wire cloth, wire cloth strainer, industrial wire cloth, metal cloth, and wire cloth. When measuring these types of materials, you will need a mesh counter. Once you have the mesh counter, the measurements are recorded the same as a coarse mesh. You take one size by counting the number of openings per linear inch and then you take another set of measurements at right angles to the original one. The measurements of finer types of mesh can also be taken with a test sieve. Test sieves work because they are used to assess the particle size distribution of smaller material.

When measuring a wire diameter, you will need a micrometer. Diameters of wires in both directions should be checked.
