SS316 marine grade covers the requirements for security screen mesh. Reproduced below: the complete specification table, the tolerance classes, and the companion and equivalent standards referenced when ordering to this document.
SS316 marine grade — Scope
SS316 marine grade specifies the designation system, dimensions and tolerances of security screen mesh — mesh count or nominal opening, wire diameter and the permissible aperture deviations. Alloy chemistry, mechanical testing and delivery condition are governed by separate documents in the same standards family.
Tolerance Classes
SS316 marine grade defines tolerance limits on the average aperture and on the maximum single aperture, tightening as the aperture gets finer. For test-sieve duty the tighter ISO 3310-1 tolerances apply instead of the general cloth tolerances — specify sieve grade explicitly if the mesh will be used for particle-size analysis.
Specifications Defined by SS316 marine grade
| Mesh count | Wire diameter (mm) | Aperture (mm) | Micron rating (u00b5m) | Open area (%) | Weight SS (kg/mu00b2) | Reference standard |
|---|---|---|---|---|---|---|
| 11-Mesh | 0.80 | 1.51 | 1509 | 42.7 | u2014 | SS316 marine grade |
| 12-Mesh | 0.80 | 1.32 | 1317 | 38.7 | u2014 | SS316 marine grade |
Companion Standards
SS316 marine grade controls the geometry of security screen mesh. Companions frequently cited alongside it: ISO 565 / ASTM E11 (test-sieve aperture series), ISO 3310-1 (test sieves of metal wire cloth), ISO 4783 (selection of wire and aperture combinations), ISO 9044 (industrial woven wire cloth), and ISO 2941 (collapse/burst rating for finished filter elements).
When to Specify SS316 marine grade
Choose SS316 marine grade for international procurement and OEM supply where ISO documents are the contractual reference. It is the default modern specification for security screen mesh.
