Custom size
This woven stainless steel wire mesh has a 0.4 mm aperture (400 µm) and a 0.25 mm wire diameter, which works out at 40 mesh. It is woven from AISI 304 (EN 1.4301, V2A) stainless steel, a general-purpose grade with good corrosion resistance for indoor and sheltered outdoor use. The 0.4 mm opening sits between coarse screening and fine filtration: it retains sand, grit and similar particles while still allowing liquids and air to pass. The 0.25 mm wire gives the cloth enough stiffness to be handled and fitted without a support layer in most sieve and filter frames. We cut every sheet to your exact width and length, so it drops into your frame or housing without further trimming.

FAQ
- What aperture and wire diameter does this mesh have?
- It has a 0.4 mm aperture (400 µm) woven from 0.25 mm stainless steel wire, which works out at 40 mesh.
- Which stainless steel grade is used?
- AISI 304 (EN 1.4301, V2A), a general-purpose stainless grade suited to indoor and sheltered outdoor applications.
- Does it need a support mesh?
- For most sieve and filter frames the 0.25 mm wire is stiff enough on its own. Under high pressure or flow, a coarser backing mesh helps keep it flat.
- Is the same mesh available in a more corrosion-resistant grade?
- Yes. The V4A (AISI 316) version has the same 0.4 mm aperture and is the better choice for marine, coastal and chemical environments.
