Specifies technical parameters, aperture dimensions, wire diameter tolerances, and verification methods for precision woven metal wire mesh.
Confirms that all 304, 316, 316L, and specialty alloy meshes are free of restricted hazardous substances and fully compliant with EU industrial regulations.
Validates our ultra-clean, degreased stainless steel woven mesh for sanitary processing, direct food contact, biopharmaceutical filtration, and medical devices.
Quality benchmarks & testing procedures
Our in-house metrology lab ensures that every shipment meets strict mechanical, geometric, and hydrodynamic parameters.
Optical Aperture Verification
Automated digital microscope scanning verifies opening tolerances and thread count across roll lengths.
Material Grade (PMI) Testing
Positive Material Identification confirms precise elemental composition (Ni, Cr, Mo) for AISI 304, 316L, and 904L.
Tensile & Yield Testing
Mechanical load testing ensures optimal tensile strength and elongation to prevent mesh distortion under differential pressure.
Bubble Point Pore Validation
Laboratory testing determines maximum pore diameter and absolute micron rating for fine micronic Dutch weaves.
Four-stage manufacturing quality gate
Guaranteed consistency across standard production runs and customized wire mesh specifications.
Raw Wire Rod Assay
Verification of raw wire alloy purity, tensile consistency, and surface finish prior to weaving.
In-Line Weave Monitoring
Continuous automated laser scanning for warp and weft tension uniformity during loom operation.
Ultrasonic Degreasing
High-frequency solvent cleaning removes all residual drawing oils and manufacturing particulates.
Final Batch Inspection & MTR
