China Stainless Steel Reversed Dutch Weave Mesh Supplier

Stainless Steel Reversed Dutch Weave Mesh

Reversed Dutch weave mesh places fine wires in the weft direction and heavier wires in the warp, creating long, narrow slots aligned with fluid flow. This configuration maximizes open area—up to 45 %—while achieving precise cut‑points. Anping CREMOTIVE’s reversed Dutch weave is produced in counts such as 200 warp × 40 weft and 300 × 50, delivering slot sizes from 10 µm × 200 µm to 5 µm × 150 µm.

Manufacturing & Materials

• Wire Selection: Weft wires down to 0.03 mm deliver fine retention; warp wires up to 0.5 mm ensure structural support.

• Double‑Crimp Process: Two‑stage crimp locking keeps wires secure, preserving slot geometry even under pulsating pressures.

• Surface Treatment: Annealing in hydrogen, pickling, and passivation yield a clean, oxide‑rich finish suitable for food, pharmaceutical, or corrosive environments.

Functional Attributes

• Low Pressure‑Drop: Aligned slots reduce turbulence and minimize flow resistance, critical in high‑flow prefiltration and membrane protection.

• Uniform Slot Tolerance: ±10 % for sub‑50 µm slots ensures predictable particle capture.

• Large Panel Spans: Rigidity of warp wires allows freestanding mesh panels and minimal backing structures.

Key Use Cases

• Water Treatment Prefiltration: Removing silt, algae, and fine debris before ultrafiltration or reverse osmosis.

• Biotech Fermentation: Sterile vent filters and broth clarification screens to protect pumps and downstream chromatography columns.

• Gas Filtration: Particulate removal in compressed‑air lines and flue‑gas cleaning.

Customization & Quality Assurance
Custom panel sizes to 2 m wide, or concentric filter cylinders to 600 mm diameter by 2 m length. All mesh is certified via image‑analysis pore measurement, pressure‑drop tests, and corrosion testing per ASTM G31.

Maintenance
In-place backwash cleaning cycles with water or dilute acid/alkali solutions can be scheduled automatically. Ultrasonic regeneration is recommended annually or when permeability falls below 70 % of baseline.
