Manufacturing Process of Decorative Expanded Metal Mesh

Discover the precise, multi-stage process underlying the production of decorative expanded metal mesh at QH Filter — a top manufacturer with 18+ years' industry experience.

Step 1: High-Grade Stainless Steel Selection
We utilize SS304/316 raw sheets conforming to EN 10088 and ASTM A240 standards, providing superior mechanical properties and anti-corrosive performance.

Step 2: Mechanical Expansion Process
Sheets are slitted and simultaneously stretched using automated CNC expansion presses to form diamond or hexagonal patterns.

Step 3: Flattening
Mesh is passed through precision rollers—for the unique surface of stainless steel flattened expanded metal and uniform mesh thickness (~±0.07mm).

Slitting & ExpandingFlatteningFinishing

Step 4: Surface Treatment
According to custom requirements: electro-polishing, PVDF coating, powder spraying, or anodizing — for corrosion protection, color, and adhesion enhancement.

Step 5: Quality Control
Rigorous inspection performed per ISO 9001:2015 and ANSI MBG 531-00 for dimensional accuracy, tensile strength, mesh uniformity, and anti-corrosion.

Step 6: Packing & Delivery
Custom-sized panels stacked, sealed, and shipped for on-time global delivery.

FAQ on Decorative Expanded Metal Mesh & Technical Terms

1. What is “LWD/SWD” in decorative expanded metal mesh?

LWD (Long Way of Diamond) is the mesh’s longest diagonal, while SWD (Short Way of Diamond) is the shortest. Both define aperture size and overall openness.

2. Which stainless steel grade should I choose: SS304 or SS316?

For general exterior/interior decorative expanded metal mesh, SS304 suffices (˜18% Cr, 8% Ni). For marine or highly corrosive sites, SS316 (with Mo addition) delivers superior salt/acid resistance.

3. What is the standard tolerance for mesh width, thickness, and aperture?

Typical tolerance is ±0.15mm for width, ±8% for aperture, and ±0.07mm for thickness (per ISO 11952, EN 12385 standards).

4. Does expanded metal mesh meet fire-resistance or safety standards?

Yes, stainless mesh is inherently non-combustible (per IEC 60695-11-10). For walkways/flooring, slip/skid resistance tested to ASTM E303/E1911.

5. How is decorative expanded metal mesh installed?

Standard options: bolted clips, welded frames, direct anchor/screw fixing (ref. EN 1090-2 for structural connections).

6. What about the sustainability and recyclability?

Mesh is 100% recyclable stainless steel or aluminum. No sharp waste is generated in mesh forming (Green Building Materials ID: CN201345989Y).

7. Is custom logo or anti-intrusion patterning supported?

Yes, via CNC/micro-jet expansion and laser etching, meeting public site security needs or brand design (minimum order applies).
