Origin of Woven Wire Mesh in Japan

The origin of woven wire mesh in Japan is believed to date back to the Asuka period when it was used in the construction of temples and shrines. Later, it began to be used in agriculture for farming tools. In the Genroku era, craftsmen started hand-weaving wire mesh using special tools, producing small quantities due to the high craftsmanship required.

During the Meiji period, industrial development and the introduction of foreign technology led to the production of wire mesh with hand looms. By the early Taisho period, the first mechanical looms were created, and Ishikawa Wire Mesh began manufacturing and selling wire mesh around this time.

After World War II, the applications of wire mesh expanded with the development of synthetic resins and semiconductors. Wire mesh became crucial for filtering dust from the air, purifying water, and various other filtration and classification tasks for liquids, gases, and solids.

Specifications of Woven Wire Mesh

Mesh (Mesh)

The unit “mesh” indicates the size of the openings in the mesh. It represents the number of openings along one side of a 25.4mm (1 inch) square. The higher the mesh number, the finer the openings. For reference, common household insect screens are 16-18 mesh. Generally, as the mesh number increases, the unit price per square meter of the wire mesh also rises.

Wire Diameter (Wire Diameter)

The diameter of the wire. The value of the aperture and the mesh number change according to the wire diameter. Common household insect screens have a wire diameter of 0.2mm. Generally, as the wire diameter decreases, the unit price per square meter of the wire mesh increases.

Aperture Width (Aperture Width)

The distance between wires is called the “aperture width,” representing the size of the mesh openings. The distance from the center of one wire to the center of the adjacent wire is called the “pitch.” Pitch length = aperture width + wire diameter. The proportion of open space in the mesh is referred to as the open area ratio (void ratio). It is expressed as: Open area ratio (%) = 100 × (aperture width ÷ pitch)^2.

Even if the open area ratio is the same, the aperture width can vary, so when selecting wire mesh, it is generally chosen based on mesh and wire diameter values rather than the open area ratio.

Types of Woven Wire Mesh

Plain Weave Wire Mesh

The vertical and horizontal wires intersect each other alternately at regular intervals. It is used as a standard wire mesh.

Twill Weave Wire Mesh

The vertical and horizontal wires pass over and under each other in pairs at regular intervals, allowing the use of thicker wires due to the larger bend angles.

Herringbone Weave Wire Mesh

This weave alternates the twill pattern at regular intervals to maintain symmetry.

Flat Top Weave Wire Mesh

The vertical wires remain at regular intervals, while the horizontal wires are closely placed, creating a pattern similar to tatami matting. Typically, thicker vertical wires are used, providing high strength.

Twilled Dutch Weave Wire Mesh

Similar to the plain dutch weave but with a twilled pattern, offering double the strength due to the closely packed horizontal wires.
