Typical Applications of Stainless Steel Security Screen Mesh
Buyers specify this heavy-gauge 304 mesh where a window, door or balcony opening must resist forced entry while staying transparent and ventilated: security window and door screens, balcony enclosures, insect-proof screens, pet-resistant screens and commercial storefront protection.
- Security windows
- doors
- balcony enclosures
- insect screens
Metallurgical Composition & Alloy Ratio Analysis
304 Wire Purity & Heat Traceability
Every 304 wire batch for this security mesh family is spectrometer-tested before weaving. The Cr 18-20% / Ni 8-10.5% balance is what gives the mesh its corrosion resistance in residential, commercial and humid environments, and each shipment includes an EN 10204 3.1 mill certificate tied to the wire heat number.
All batches are tested via handheld PM-I spectrometer before Tianjin Port export, guaranteeing material compliance.
304 Physical & Service Limits
- Max Oxidation Temperature：Resists scaling in continuous air service up to 870°C; intermittent service limit is 925°C.
- Sensitization Warning：Holding 304 in the 425-860°C range precipitates chromium carbides at grain boundaries. For welded security screen frames running in that band, ask us about the low-carbon 304L version.
- Yield Strength：205 MPa minimum in annealed condition, rising to 310 MPa after the cold-drawing used for weaving wire, which is what lets heavy 0.4-0.9 mm strands hold the weave stable under impact.
- Food Contact：Complies with FDA food-contact requirements, safe for use near food preparation areas and kitchens.
ASTM E2016-22 Reference Tolerances for Security Screen Mesh
This family's 10-18 mesh range spans the woven wire cloth tolerance bands referenced by ASTM E2016-22. Finished security screens are certified at product level under standards such as AS 5039, which includes the knife-shear test for Australian security doors; this page states the wire-cloth level tolerances we hold in production, and every pre-shipment report includes actual measured values.
| Nominal Mesh Range | Max Wire Dia. Tolerance | Max Aperture Size Tolerance | Warp Tilt Deviation |
|---|---|---|---|
| 1 to 50 Mesh | ± 0.013 mm (0.0005 inch) | ± 3% of nominal aperture | Tilt deviation ≤ 2° |
| 51 to 200 Mesh | ± 0.008 mm (0.0003 inch) | ± 5% of nominal aperture | Tilt deviation ≤ 1.5° |
| 201 to 400 Mesh | ± 0.004 mm (0.00015 inch) | ± 8% of nominal aperture | Tilt deviation ≤ 1° |
