Ultra-thin Stainless Steel Mesh

Ultra-thin Stainless Steel Mesh is a high-precision woven metal mesh manufactured from exceptionally fine stainless steel wires.With micron-level wire diameters, uniform openings, and outstanding flatness, it is designed for demanding applications such as EMI/RFI shielding,high-density screen printing, and precision filtration. By combining carefully selected stainless steel alloys with advanced weaving technology,
the mesh delivers excellent mechanical strength, stability, and long-term reliability in harsh environments.Thanks to its thinness, strength, and flexibility, Ultra-thin Stainless Steel Mesh is widely used in electronics, medical devices,aerospace, scientific instruments, and high-end industrial processes where both fine detail and high performance are critical.

What Is Ultra-thin Stainless Steel Mesh?

Ultra-thin Stainless Steel Mesh is a woven wire cloth made from very fine stainless steel wires, often with diameters from about 0.02 mm to 0.08 mm (and even smaller for special grades). Despite its extremely low thickness, it maintains high tensile strength and dimensional stability.

The mesh features:

• Precisely controlled mesh count (number of openings per inch)
• Uniform square or rectangular openings
• Stable thickness within tight tolerance ranges
• Excellent surface flatness for accurate printing and sealing

These characteristics make it ideal for applications requiring high precision, such as fine screen printing, micro-filtration,
gas diffusion, EMI/RFI shielding and optical testing.

Materials & Weaving Technology

Ultra-thin Stainless Steel Mesh is typically produced from premium stainless steel grades, including:

• SS304 / 304L / 304HC – good overall corrosion resistance and mechanical strength
• SS316 / 316L – enhanced resistance to corrosion, chemicals, and high-temperature environments

Standard weaving type:

Plain weave – each warp wire alternately passes over and under each weft wire, creating a stable,flat and uniform mesh ideal for ultra-thin constructions.For special technical requirements, other weaving styles (such as twilled weave and Dutch weaves) can also be supplied to adjust flow rate, strength and filtration performance.

Key Manufacturing Features

• Exceptionally fine wire diameter: often from 0.022 mm to 0.065 mm or even finer
• Tight dimensional tolerance: controlled mesh count, aperture size and thickness
• Advanced tension control: precise warp/weft alignment and very low mesh distortion
• Microscopic inspection: every roll or sheet is inspected for opening uniformity, flatness and defects

This combination of high-grade raw material and precision weaving results in Ultra-thin Stainless Steel Mesh with outstanding consistency and repeatable performance from batch to batch.

Core Properties of Ultra-thin Stainless Steel Mesh

• High precision & uniform openings:
  Mesh openings and wire diameters are tightly controlled, ensuring reliable, repeatable performance in printing, filtration and shielding.
• High strength at ultra-thin thickness:
  Despite the tiny wire diameter, stainless steel provides excellent tensile strength and structural stability under tension or pressure.
• Low elongation & shape stability:
  The mesh maintains its geometry under load, which is crucial for high-tension screen printing and EMI shielding frames.
• Outstanding corrosion & heat resistance:
  Stainless steel grades such as 304 and 316/316L provide reliable performance in humid, chemical and high-temperature environments.
• Smooth, flat surface:
  Precision weaving and careful tension control produce a flat, smooth mesh surface ideal for screen printing, coating and optical applications.
• Excellent electrical conductivity:
  The metallic structure provides efficient EMI/RFI shielding and is suitable for Faraday cages and shielded windows.
• High transparency & air permeability:
  Fine openings and thin wires ensure good light, air and fluid transmission while providing the necessary physical barrier.
