Micro Expanded Metal Sheet: Ultra-Fine Precision Mesh
ANPING METAL MESH – Professional Metal Mesh Manufacturing Since 2005
Micro expanded metal sheet is an ultra-fine, high-precision expanded metal product with miniature diamond openings, ultra-thin material, and smooth flattened surfaces. Designed for precision industries, it offers excellent ventilation, filtration, shielding, and structural support in compact applications.
As a leading manufacturer based in Anping County – the global Wire Mesh Capital – we specialize in custom micro expanded metal sheets using stainless steel, aluminum, and galvanized steel. Our micro mesh is widely used in precision industrial components, electronic equipment, filters, and high-end architectural details worldwide.
What Is Micro Expanded Metal Sheet?
Micro expanded metal sheet is produced through a precision cold-expansion process that creates tiny, uniform diamond openings from thin metal sheets. Unlike standard expanded metal, micro mesh features extremely small openings (as small as 1mm × 2mm) and ultra-thin metal thickness (from 0.1mm to 0.5mm).
It maintains the one-piece structure of expanded metal (no welding or weaving) while delivering a smooth, flat, and high-strength surface ideal for miniaturized equipment, precision filtering, and delicate design applications.
Our micro expanded metal is available in both flattened and raised finishes, with customizable dimensions to meet strict industrial and electronic standards.
Materials for Micro Expanded Metal Sheet
We use high-grade, corrosion-resistant materials to ensure durability and performance in precision environments:
1. 304 / 316 Stainless Steel
The most popular choice for micro mesh. Offers excellent rust resistance, heat resistance, and food-grade safety. Used in medical devices, filters, electronics, and marine applications.
2. Aluminum Alloy
Ultra-lightweight, non-magnetic, and rust-proof. Ideal for electronic components, speaker grilles, heat dissipation panels, and lightweight aerospace parts.
3. Galvanized Steel
Cost-effective precision mesh for industrial shielding, ventilation panels, and general-purpose precision components.
4. Copper / Brass (Custom)
High-conductivity and decorative micro mesh for electronics, artistic design, and electrical components.
Standard Precision Specifications
| Material | Thickness | Diamond Opening (SWD × LWD) | Surface | Application |
|---|---|---|---|---|
| 304 Stainless Steel | 0.1mm–0.5mm | 1×2mm / 2×3mm | Flattened / Bright | Medical / Filter |
| Aluminum | 0.2mm–0.6mm | 1.5×3mm / 2×4mm | Flattened / Mill | Electronics / Speaker |
| Galvanized Steel | 0.2mm–0.6mm | 2×4mm / 3×6mm | Flattened | Industrial / Shielding |
| 316 Stainless Steel | 0.15mm–0.5mm | 1×2mm / 1.5×3mm | Flattened / Brushed | Marine / Medical |
All micro expanded metal sheet products are manufactured under strict quality control for consistent opening size and smooth surface finish.
Key Advantages of Micro Expanded Metal Sheet
- Ultra-Precise Openings: Uniform miniature diamond patterns for consistent performance
- High Strength-to-Weight Ratio: One-piece structure, no breaks or weak joints
- Smooth Flattened Surface: Burr-free, safe for precision equipment and touch surfaces
- Excellent Ventilation & Filtration: Fine openings for air, liquid, and sound control
- Corrosion Resistant: Stainless steel & aluminum for long-term use
- Customizable Size: Can be cut to small or large sheets for any project
- Cost-Effective: Lower cost than photo-chemical etching or woven wire mesh
These benefits make micro expanded metal the first choice for engineers and designers in high-precision fields.
Common Applications
