Five-Heddle Weave Mesh (ISO 9044) is specified where the duty calls for precision filtration, sieving and separation where a defined aperture and open area are required. The sections below cover the typical end-uses by industry, the mesh, micron and material decisions for each, installation practice, and the applications this product type is not suited to.
Typical Applications for Five-Heddle Weave Mesh
The most common settings where this is specified:
- Industrial filtration & separation: removing particulates from liquids, gases and slurries in process plant.
- OEM & fabrication: cut, formed and welded into filter assemblies, screens, guards and enclosures.
- Maintenance & replacement (MRO): matching an existing mesh, screen or element spec when servicing installed equipment.
- Oil, gas & petrochemical: sand screens, strainers and catalyst support in refining and production.
- Food, beverage & pharma: sieving, sifting and CIP-friendly filtration in 316L stainless.
How to Specify Five-Heddle Weave Mesh for Your Application
- Mesh count / micron rating: Match the aperture or micron rating to the smallest particle you must retain or pass. The table below lists mesh count, aperture and micron for each option — for woven cloth, specify the aperture or micron, not just the mesh count.
- Weave: Choose the weave: plain and twill for square-aperture sieving, plain/twill dutch for the finest pore filtration, reverse dutch for high flow.
- Material / alloy: Select the alloy for the environment — 304 for general use, 316L for chlorides, food and chemicals, brass or copper for shielding, and Monel, Inconel or Hastelloy for marine, acid and high-temperature service.
- Environment: For damp, coastal, chemical or high-temperature service move up to 316L or a nickel alloy; for dry indoor duty 304 or a coated steel is usually enough.
- Standard: This product is supplied to ISO 9044. Quoting the standard on your order guarantees interchangeable dimensions and filtration data between suppliers.
Handling & Installation Practice
- Seal or lock-crimp cut edges, or fit a binding/frame, so fine wires cannot fray and shed into the filtrate.
- Support the cloth on a backing grid or perforated plate when it works against pressure — unsupported fine mesh distorts and the aperture opens up.
- In a multi-layer pack, keep the coarse guard layer facing upstream and the fine layer downstream.
Common Selection Mistakes with Five-Heddle Weave Mesh
- Specifying by mesh count alone — two cloths of the same mesh but different wire diameters have very different apertures and open areas; quote aperture or micron as well.
- Assuming mesh count equals micron rating; a woven cloth passes particles larger than its nominal aperture, so confirm the actual micron rating for the weave.
- Using a plain square weave for fine filtration where a dutch weave, with its much finer effective pore, is the correct choice.
Where Five-Heddle Weave Mesh Is Not the Right Choice
Not for structural containment or where sharp, heavy solids will tear fine cloth — use welded or perforated mesh there; and filtration below the weave limit needs a sintered or membrane medium.
