Understanding Woven Wire Mesh Sizes

Understanding Woven Wire Mesh Sizes is essential for anyone working with this versatile material. Woven wire mesh, often referred to as wire cloth, is constructed from metal wires arranged in a grid pattern. It finds extensive applications for filtering, sieving, shielding, and decorative purposes.

In this article, we address common queries related to the sizing of woven wire mesh, aiming to clarify the important specifications.

Specifying Wire Mesh or Wire Cloth for Applications

Woven and welded wire mesh come in various sizes and types. This section breaks down how to measure wire mesh and explore the criteria that determine the appropriate mesh size for different industries and applications.

How Wire Mesh is Measured

Mesh Count

Mesh count is a critical parameter when specifying wire mesh. The mesh count is calculated differently depending on the type of weave - Square or Dutch.

• Square Weave Mesh Count: Indicates the number of spaces in one linear inch. A lower mesh count denotes fewer wires and spaces, while a high mesh count implies many wires per square inch. For instance, a mesh count of #20 indicates 20 spaces per linear inch.
• Dutch Weave Mesh Count: Specifies the number of wires in one linear inch, represented by two numbers (e.g., 12*64) where the first number refers to the warp (long) direction, and the second to the chute (width) direction.

Opening Size

In some cases, mesh is defined by its opening size rather than the mesh count. The opening size refers to the clear space between adjacent wires and is independent of wire diameter. For square mesh, it is calculated using the formula: where D is wire diameter and M is mesh count. This sizing may also be termed as Space Cloth.

Open Area Percentage

The open area represents the percentage of voids between the wires that allow air or liquids to flow. This can be calculated using a specific formula for square weaves.

Micron Mesh Specification

Micron mesh indicates a high mesh count, typically a Dutch weave but can also involve a Plain Weave. This type of mesh is predominantly employed in filtration applications due to its very fine openings.

Micron Rating

The Micron rating for Square Mesh is calculated using the Open Area % formula. For Dutch weaves, it is measured by determining the largest particle size capable of passing through, using laboratory-grade glass beads.

Wire Mesh vs. Wire Cloth

Wire Mesh and Wire Cloth fundamentally refer to the same material, differing only in the weave style. Wire Mesh typically has larger openings and is commonly used for cages and screens, while Wire Cloth has smaller openings and is used for filtration.

Choosing the Right Specification for Your Application

When specifying wire mesh, it’s critical to know your required Mesh Count, opening size, or open area percentage. Multiple specifications may suit a single application, and understanding your needs can significantly influence cost and material efficiency.
