If you’ve been trawling specs and standards all week, here’s the short version: ce certification 250 micron stainless steel mesh isn’t just about the aperture. It’s documentation, process control, and making sure your mesh can sit inside a CE-marked assembly (filters, machine guards, process skids) without tripping auditors. And yes, the vendor matters more than most people admit.

Two trends keep popping up: food and pharma plants upgrading to hygienic designs (think EN 1672-2 compliance) and battery/EV facilities standardizing on traceable 316L filtration screens. Surprisingly, even quarries are asking for CE-ready documentation for guard meshes under the Machinery Directive. It seems audits are getting stricter.
From East Industry, Anping City, Hebei (not exactly a secret in the mesh world), the Black Wire Crimped Wire Mesh is built with pre-crimping before weaving—two-way separated wave, locked bending, flat-top, you name it. Materials on the stainless side include 304, 304L, 316, 316L; black wire is there for heavy-duty screens. The structure is firm and durable; many customers say it outlasts generic import stock in mining and coal plants. Packaging? Plastic film, then pallet—survives a rough voyage, in my experience.
| Parameter | Value |
|---|---|
| Aperture (nominal) | ≈ 250 μm |
| Wire diameter | ≈ 0.16–0.20 mm (app-dependent) |
| Open area | ≈ 30–40% |
| Alloys | 304/304L, 316/316L; black wire for crimped screens |
| Weave | Plain/twill for 250 μm; pre-crimped for screens |
| Roll width / length | 1.0–1.5 m / 30 m typical; cut panels on request |
| Standards | ISO 9044, ASTM E2016; EN 10204 3.1 certs on request |
Materials: 304/316L melt with low sulfur for clean weldability. Methods: pre-crimping (for structural screens), precision weaving, optional anneal, ultrasonic cleaning. Testing: aperture verification per ISO 9044, wire dia micrometry, flatness/warp checks, and salt-spray (ASTM B117) for black wire frames where relevant. Service life: around 3–10 years depending on abrasion, chemistry, and cleaning regime.

Raw mesh doesn’t get CE-marked by itself; the assembly (filter housing, guard panel, pressure equipment) does. Still, buyers ask for ce certification 250 micron stainless steel mesh because auditors want material traceability (EN 10204 3.1), conformity to ISO 9044/ASTM E2016, and a Declaration supporting the end product’s CE file. So the right docs make integration painless.
| Criteria | Wiremeshbst (Anping) | Generic Importer | Local Fabricator |
|---|---|---|---|
| EN 10204 3.1 docs | Standard on request | Sometimes missing | Available, costlier |
| ISO 9044 compliance | Yes, batch-tested | Variable | Yes |
| Customization | Aperture, alloy, frames | Limited | High, longer lead time |
| Lead time | Fast for stock sizes | Uncertain | Predictable |
Aperture 250 μm with plain or twill weave; 304/316L; roll or cut panel; pre-crimped for impact-heavy screens; framed guards to EN ISO 14120; passivation; edge welding. For mining, black wire crimped mesh with locked bends still rules—no surprise there.
