Hexagonal Hole Perforated Sheet is used primarily for high open-area decorative facades and screening. This page lists the industries and assemblies where it is specified, the selection criteria that matter for each application, handling and installation practice, and the cases where a different mesh, screen or filter type is the correct choice. It is supplied to DIN 24041 (Hv).
Typical Applications for Hexagonal Hole Perforated Sheet
The most common settings where this is specified:
- Acoustic & filtration: speaker grilles, silencers and filter cores.
- Machine guarding: ventilated covers and safety panels.
- 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.
How to Specify Hexagonal Hole Perforated Sheet 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.
- Hole pattern & open area: Pick round, slotted or hexagonal holes and the pitch that gives the open area your flow or sightline needs.
- 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 DIN 24041 (Hv). Quoting the standard on your order guarantees interchangeable dimensions and filtration data between suppliers.
Handling & Installation Practice
- Allow for the closed margin when cutting to size, and keep the open area oriented to the flow or sightline you designed for.
- Deburr punched edges, and where the part is bent, run the bend across the pattern to avoid tearing between holes.
Common Selection Mistakes with Hexagonal Hole Perforated Sheet
- Choosing an open area too low for the required flow, then finding the screen blinds and starves the process.
- Forgetting the closed margin and pitch when detailing a panel, so the pattern does not line up with the frame or fixings.
Where Hexagonal Hole Perforated Sheet Is Not the Right Choice
Not for very fine filtration (the smallest economical holes are around 0.5 mm), and not where maximum open area at minimum weight is the priority — expanded or woven mesh suit better.
