Wire Mesh

Wire mesh is a woven structure made from metallic wires arranged in warp and weft to create repeatable apertures. In industrial filtration and process belts, stainless steel grades (e.g., 1.4404/316L) dominate for their corrosion resistance, thermal stability and dimensional precision; specialty alloys extend into aggressive chemistries or high‑temperature zones. Mesh parameters—mesh count, wire diameter, aperture/open area and weave (plain, twill, Dutch, reverse‑Dutch)—determine cut‑off, permeability, thickness and mechanical stiffness. Compared to polymer cloths, wire meshes offer superior cut resistance, stable pore geometry under load, low creep and excellent cleanability; they also tolerate sterilisation and hot CIP. Correct specification aligns aperture or mean‑flow pore size to the feed PSD, defines surface finish for reliable cake release, and states tensile properties for tensioning and flex over rollers. In composite media, a fine wire top layer can be laminated to a coarser support to combine sharp retention with low pressure drop. Quality assurance relies on porometry, permeability and bubble‑point tests, complemented by weld/seam integrity checks to avoid bypass in assemblies.
