Twill Dutch weave wire mesh
High-Pressure Micron Liquid & Polymer Filtration Media
Combines a twilled warp arrangement with compacted weft wires to produce a dense, light-tight mesh structure. Engineered for ultra-fine liquid, gas, and polymer melt separation where extreme differential pressure demands mechanical stiffness and accurate particle cut-offs down to 1 micron.

Alloy selection & chemical composition
Twilled dutch weaves require high ductile elongation wire to achieve dense packing without internal micro-fractures. We stock prime certified wire in austenitic stainless grades.
Require non-standard aperture or custom slit rolls?
We supply slitted rolls, stamped discs, welded cylinders, and multi-layer sintered packs.
