4 mesh hook-strip tensioned screen panel has 4 openings per linear inch. Woven to ISO 9044 / screen OEM decks with a standard aperture of 5.35 mm (5350 µm), this page lists the controlling specification — wire diameter, aperture, micron rating, open area and cloth weight — together with the wire options available at this count and the duties it is normally specified for.
4 Mesh Specification Row (ISO 9044 / screen OEM decks)
| Mesh count | Wire diameter (mm) | Aperture (mm) | Micron rating (u00b5m) | Open area (%) | Hook |
|---|---|---|---|---|---|
| 4-Mesh | 1.600 | 4.750 | 4750 | 56.0 | 30u00b0 side hook |
4 Mesh to Micron & Aperture
| Openings per inch | 4 |
|---|---|
| Aperture (opening width) | 5.35 mm |
| Micron rating | 5350 µm |
| Standard wire diameter | 1 mm |
| Open area | 71 % |
Aperture = (25.4 mm ÷ mesh count) − wire diameter. The micron rating equals the aperture in micrometres; actual retention also depends on particle shape and cake formation.
Wire Diameter Options at 4 Mesh
| Option | Wire dia | Aperture | Micron | Open area | Weight (SS) |
|---|---|---|---|---|---|
| Heavy wire | 1.300 mm | 5.050 mm | 5050 µm | 63.2 % | 3.48 kg/m² |
| Standard wire | 1.000 mm | 5.350 mm | 5350 µm | 71.0 % | 2.06 kg/m² |
| Fine wire | 0.750 mm | 5.600 mm | 5600 µm | 77.8 % | 1.16 kg/m² |
Heavier wire adds strength and abrasion life but closes the aperture; finer wire opens the aperture and raises throughput at the cost of durability. Specify mesh count AND wire diameter to fix the aperture unambiguously.
Open Area & Flow at 4 Mesh
The standard 4 mesh weave presents an open area of about 71%. At this count the mesh presents little flow resistance; selection is normally driven by particle retention and mechanical strength rather than pressure drop.
4 Mesh Cloth Weight
Standard 4 mesh stainless cloth weighs approximately 2.06 kg/m² (density 7.93 g/cm³ basis; brass and copper weave roughly 10% heavier, aluminum about one third). Use this figure for roll handling and freight estimation.
Typical Applications for 4 Mesh Hook-Strip Tensioned Screen Panel
4 mesh hook-strip tensioned screen panel is commonly specified for coarse screening and grading, safety guarding, animal enclosures, plaster and render reinforcement, and support layers behind finer filter cloth.
Plain, Twill or Dutch Weave at This Rating?
Plain square weave is the standard at this count: every opening is a true square of the stated aperture, retention is absolute for hard spherical particles, and the cloth is easy to clean.
When to Step Up or Down from 4 Mesh
Move to 8 mesh when particles are passing that must be retained; drop back to 2 mesh when the element blinds too quickly or the pressure drop is excessive. In a multi-layer pack, pair this count with a coarser support mesh downstream to carry the pressure load.
What Hook-Strip Tensioned Screen Panel Does
Screening aggregates, ore, coal and recycled material on vibrating screen decks with woven wire panels whose folded hook strips let the panel be side-tensioned tight across the deck.
Fitting & Care
- Fit new rubber channel strips on the crowned support bars before tensioning.
- Tension evenly from both sides and re-check after the first hours of running.
