Woven metal cloth (or woven wire mesh) is a go-to for a notably wide range of industrial applications. Since it has so many uses, there are countless variations, which can make it challenging to determine the correct material for a specific application.
Wire Mesh Specifications
Not sure which type, size, or weave you need? Consider this your guide to commercial-grade wire mesh specifications.
Key Wire Mesh Definitions
First, let's go over a few of the most common terms used to describe and classify wire mesh products.
Mesh Count: Measured from the midpoint of a single wire to a 1-inch distance, mesh count is the number of openings per linear inch.
Mesh Opening: Mesh opening refers to the hole size. Typically measured in inches, it's the distance between the two closest parallel wires.
Wire Diameter: Also known as gauge, the diameter measures the thickness of a round wire.
Filter Rating: A filter rating, also referred to as Minimum Efficiency Reporting Values (or MERVs), tells you whether wire mesh can effectively remove particles of a certain size from other matter. It's essentially a measure of retention and is usually expressed in microns or percentages.
Absolute Filter Rating: Mesh with an absolute filter rating has a retention of nearly 100% (ranging from 99.7% to 99.99%).
Nominal Filter Rating: Wire mesh with a nominal filter rating has a retention between 60% to 90%.
Weave: This refers to the specific over-under pattern of intersecting wires. Similar to textiles, metal mesh comes in various weave styles.
Shute Wires: These are the metal wires that run across the width.
Warp Wires: These are the metal wires that run down the length of the mesh.
Finish: Finish refers to the surface of fabricated metal mesh. The most common finishes include mill (dull and free of texture) and polymeric coated, which is finished with a PVC (polyvinyl chloride) material.
Galvanized: To create galvanized hardware cloth, mesh is dipped into molten zinc. This forms an ultra-strong metal alloy.
Welded: Welded wire mesh is made using resistance welding to join intersecting wires and ultimately form a grid.
Wire Mesh Weave Types
The most common weaves include plain, plain Dutch, twill, and twill Dutch. Find a rundown of each below.
Plain Weave (PW): Plain weave mesh accounts for a majority of industrial products. The shute and warp wires alternate passing over, then underneath each other to create a standard square grid.
Plain Dutch Weave (PDW): With PDW mesh, the warp wires have a larger gauge than the shute wires. As such, this weave features fewer warp wires than shute wires.
Twill Weave (TW): Twill weave mesh is made by crossing each shute wire over two, then under two warp wires to create a strong diagonal pattern.
Twilled Dutch Weave (TDW): Then there's twill Dutch, which is like plain Dutch but with a twill pattern.

Wire Mesh vs. Hardware Cloth
Wire mesh is created by weaving or welding metal wires to create a grid. While the terms are often used interchangeably, hardware cloth is a type of wire mesh that's usually galvanized.
Welded vs. Woven
As mentioned above, metal mesh can be formed either through weaving or welding. Woven mesh is created by connecting shute and warp wires with an alternating over-under pattern. The welded variety calls for heating the wires with an electric current to permanently intersect them.
Welded mesh is exceptionally strong and boasts impressive rigidity. However, not all industrial applications require this level of inflexibility, and for some, malleability is essential.
