Reverse Dutch weave wire mesh
Engineered for high tensile loads, continuous screen belts & high-pressure polymer melt filtration. Unlike conventional Dutch weave, heavier weft wires are positioned tightly across closely spaced thinner warp wires to produce high longitudinal tensile strength, exceptional differential pressure resistance, and reliable throughput for viscous polymers.
Reverse Dutch weave specifications
Detailed dimensional tolerances, pore ratings, and standard alloy availability for heavy-duty filtration belts and pressure screens.
High Mechanical Rigidity
Thicker warp wires along the longitudinal axis prevent necking and withstand extreme continuous extrusion pressure without mesh deformation.
Precise Retention Profile
Tightly packed weft wires create triangular pore openings with predictable particle retention curves down to 10 microns absolute.
Continuous Belt Reliability
Engineered specifically for automatic screen changers in polymer recycling, melt blown, and high-viscosity chemical processing lines.
Certified Alloy Tracing
Supplied with EN 10204 3.1 chemical analysis and PMI spectroscopic testing for harsh chemical and offshore environments.

Pore retention values verified via ASTM F316 bubble point testing and glass bead challenge tests. Absolute values represent 99.9% retention efficiency.
Full 3.1 chemical & physical mill test certificates, RoHS, REACH, and FDA conformity declarations supplied with every production batch.
Applications for reverse dutch weave mesh
Built for high-pressure filtration and continuous mechanical tension across demanding industrial separation lines.
Custom mesh slit rolls and engineered screen specifications
MutualFilter supplies reverse dutch weaves in slit coils, continuous belts, stamped discs, and welded filter tubes. Standard alloys include AISI 304, AISI 316L, 904L, Alloy 20, and custom high-nickel wires.
Fine Filtration Mesh with High Flow Rate Capability
Reverse Dutch weave inverts conventional wire geometry by pairing heavier, stouter warp wires with dense, tightly beaten weft wires. This deliberate structural orientation delivers exceptional mechanical resistance under high differential pressure alongside sustained volumetric throughput for demanding continuous process filtration.
