I. Core Specification Parameters of Stainless Steel Wire Mesh
The specifications of stainless steel wire mesh are mainly determined by the following four parameters:

Mesh count: It refers to the number of mesh holes per inch (25.4mm) in length. The commonly used mesh sizes range from 10 to 400 mesh, such as 20 mesh (with an aperture of approximately 0.9mm) and 100 mesh (with an aperture of approximately 0.15mm). The higher the mesh count, the finer the filtration accuracy.

2. Wire diameter: The diameter of the steel wire, typically ranging from 0.02mm to 2mm. For example, in 304 stainless steel wire mesh, the wire diameter corresponding to 100 mesh is 0.1mm (refer to the national standard GB/T 5330-2003).

3. Materials: Common ones are 304 (corrosion-resistant), 316 (acid and alkali resistant), and 316L (medical grade). The applicable environments for different materials vary significantly.

4. Weaving methods: Plain weave (the most commonly used), twill weave (high strength), mat type (ultra-fine filtration).

Data source: The corresponding relationship between mesh count and wire diameter is based on "Industrial Metal Wire Woven Square Hole Screen Mesh" (GB/T 5330-2003). In actual production, a tolerance of ±5% is allowed.

Ii. Specification Selection Guide for Different Scenarios
1. Industrial filtration

- Petrochemical industry: 80-200 mesh 316L material is mostly used, with a wire diameter of 0.12-0.3mm, and it is resistant to acid and alkali corrosion.

- Dust screening: 40-60 mesh plain weave is recommended, with a wire diameter of 0.3-0.5mm (such as in the cement industry).

2. Food processing

- Flour sieve: Usually made of 120-mesh 304 stainless steel with a hole diameter of 0.12mm, it complies with FDA standards.

- Juice filtration: A 200-mesh or larger mesh screen is required to prevent fiber residue.

3. Architectural decoration

- Protective net: Select 6-10 mesh, wire diameter 1-2mm, with strong impact resistance.

- Curtain wall decoration: 30-50 mesh twill weave, taking into account both light transmission and aesthetics.

Iii. Extended Suggestions
- Special requirements: If anti-magnetic properties are needed, it is recommended to choose 316L material. 310S stainless steel should be selected for high-temperature environments (> 800℃).

- Customized service: Non-standard specifications can adjust the weaving density or coating (such as galvanizing to enhance wear resistance).

Based on the above parameters and scenario analysis, users can precisely match the specifications of stainless steel wire mesh, enhancing its usage efficiency and lifespan.
