Detailed Process Flow: Manufacturing High-Quality Square Mesh

The manufacturing of square mesh involves a meticulous multi-stage process designed to ensure structural integrity, dimensional accuracy, and optimal material properties. Our commitment to ISO 9001 certified quality management ensures adherence to the highest international standards at every step.

1. Material Selection and Preparation

The foundation of superior square mesh lies in the quality of raw materials. We primarily utilize high-grade stainless steel (e.g., SS304, SS316, SS316L for enhanced corrosion resistance), galvanized steel (for economic corrosion protection), and low carbon steel. These materials are chosen based on the intended application's demands for strength, corrosion resistance, temperature tolerance, and ductility. Raw wire coils undergo rigorous inspection for consistent diameter, tensile strength, and surface finish before processing.

2. Wire Drawing and Straightening

If the desired wire diameter is finer than the raw material, a wire drawing process is employed. This cold-working process reduces the wire's cross-section while increasing its tensile strength. Subsequently, wires are straightened and cut to precise lengths using automated machinery to ensure uniformity, critical for mesh consistency. For very fine mesh, precision CNC machining of the drawing dies ensures micron-level accuracy.

3. Weaving or Welding

• Woven Square Mesh: Wires are interlaced at right angles on high-speed weaving looms, similar to textile weaving. The "plain weave" is most common for square mesh, where warp (longitudinal) and weft (transverse) wires pass over and under each other alternately. This method offers flexibility and excellent material efficiency.
• Welded Square Mesh: Pre-straightened longitudinal and transverse wires are precisely positioned and then resistance-welded at each intersection. This process, often automated, creates a rigid, dimensionally stable mesh with higher load-bearing capacity and a flatter surface, ideal for structural applications.

4. Finishing and Surface Treatment

After weaving or welding, the mesh may undergo various finishing processes:

• Cleaning: Removal of oils, dirt, and residues.
• Edge Treatment: Trimming, selvaging, or binding edges to prevent unraveling and ensure safety.
• Surface Coatings: Galvanization (hot-dip or electro-galvanized) for carbon steel mesh, PVC coating for enhanced aesthetic appeal and corrosion resistance, or specialized coatings for chemical resistance or anti-friction properties.
• Annealing: For certain applications requiring increased ductility or stress relief in stainless steel mesh.

5. Quality Control and Testing Standards

Each batch of square mesh undergoes stringent quality checks to meet both internal standards and international specifications like ISO (International Organization for Standardization), ASTM (American Society for Testing and Materials), and ANSI (American National Standards Institute).

• Dimensional Accuracy: Mesh opening size, wire diameter, and panel/roll dimensions are verified using precision instruments.
• Tensile Strength Test: To ensure the mesh can withstand specified loads without deformation.
• Corrosion Resistance Test: Salt spray tests or chemical immersion tests for coated or stainless steel meshes.
• Weld Integrity Test: For welded mesh, checking the strength of individual welds.
• Visual Inspection: For defects such as broken wires, inconsistencies in weaving/welding, or surface imperfections.

6. Packaging and Dispatch

Finished square mesh is carefully packaged, typically in rolls or flat panels, to prevent damage during transit. Robust packaging materials and methods are employed, often including waterproof paper, plastic film, and wooden pallets or crates, ensuring products arrive at their destination in pristine condition.

Service Life and Target Industries

The service life of square mesh varies significantly with material, application environment, and maintenance. Stainless steel mesh can offer decades of service in corrosive environments, while galvanized mesh provides reliable performance for 5-15 years depending on coating thickness and exposure. These products are indispensable in target industries such as:

• Petrochemical: For filtration, catalyst support, and separation.
• Metallurgy: Sifting, screening, and furnace grates.
