Stainless Steel Square Wire Mesh | SS304/316 Plain & Twill Weave

Stainless Steel Square Wire Mesh | Precision Filtration Solutions

BZ Stainless Steel Square Wire Mesh is engineered for high-performance filtration and separation across industries. Featuring perfectly uniform openings and exceptional resistance to acids, alkalis, and extreme temperatures, our mesh provides reliable durability for petroleum, chemical, and food processing applications.

● Premium Filtration Solutions:

Stainless steel square wire mesh is a commonly used product where the mesh count in width and length are equal, resulting in a square hole shape. It is manufactured using high-quality wire and woven via precision machines in various styles.

Key Features:

・Uniform Surface: Flat and consistent weave for precise filtration.

・Extreme Resistance: Excellent durability against acid, alkali, and high temperatures.

・Mechanical Strength: High wear resistance and strength for heavy-duty industrial use.

・Easy Processing: Versatile material suitable for custom fabrication into filters or screens.

Technical Parameters & Weave Types

The mesh is defined by three primary parameters: Wire Diameter, Mesh Opening Size, and Mesh Count. The third parameter is determined once the other two are decided.

Square Wire Mesh Specification Marking Method

● Mesh Calculation Formulas:

・Mesh Size = 25.4÷(Dia+Opening)

・Mesh Opening = (25.4÷Mesh Count)−Dia

・Opening Rate = Opening²÷(Opening+Dia)²

1. Wire Diameter (D) mm

2. Mesh Opening (O) mm

3. Mesh Count (Per Inch)

4. Opening Rate (%)

● Common Weave Styles:

・Plain Weave: Typically used for lower mesh counts.

・Twill Weave: Normally used for higher mesh counts (fine mesh over 150 mesh).
