What is stainless steel security screen mesh?

It is a plain-weave stainless steel wire mesh woven from heavy-gauge 304 wire, typically 0.4-0.9 mm in diameter, into an open square grid of about 10-18 mesh. Unlike thin aluminum or fiberglass insect gauze, the heavier wire and locked weave resist cutting, impact and forced entry, so it is installed in security windows, security doors, balcony enclosures and insect screens where protection and visibility must go together.

What mesh count is best for a security screen?

The common working range is 11-14 mesh with 0.5-0.9 mm wire. Lower mesh counts with thicker wire give higher strength and clearer visibility; higher counts like 16-18 mesh with 0.4-0.45 mm wire trade some strength for finer insect protection and a smoother look. Tell us your window or door size and threat level, and we will recommend the specification that balances strength, airflow and transparency.

Should I choose 304 or 316 stainless steel for a security screen?

304 is the cost-effective standard for most residential and inland installations. For coastal locations, salt spray or industrial atmospheres, 316 with its 2% molybdenum resists pitting corrosion significantly better, since molybdenum is what enhances corrosion resistance in marine environments. Send your location and we will quote both grades.

Does security mesh also keep insects out?

Yes, within limits. The 16-18 mesh options have apertures around 1.0-1.14 mm, which blocks most mosquitoes and flies. Coarser 10-12 mesh with apertures above 1.4 mm stops larger insects and debris but may admit the smallest insects, so buyers who need full insect exclusion alongside security often pick 16-18 mesh or combine the screen with a fine insect layer.

Is stainless steel security mesh cut-proof?

No screen is 100% cut-proof, and we do not claim that. Heavy 304 wire at 0.8-0.9 mm substantially raises the time, tools and noise needed to breach the screen, and the same reasoning sits behind knife-shear testing in standards like AS 5039, where 304 strands must be thicker than 316 to pass the test. The mesh deters and delays forced entry; pair it with a quality frame and lock for a complete security system.

What roll widths, colors and sample options are available?

Standard rolls are 0.6 m, 0.9 m, 1.2 m and 1.5 m wide, with cut-to-size panels available. Natural bright finish, black powder coating and gunmetal electrostatic spray are the common finishes. Free 200 mm x 200 mm samples of standard specifications are dispatched within 1-2 days via DHL or FedEx for buyers with purchasing intent.

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°
