metalmesh

Metalmesh refers to a family of metal-based mesh products consisting of wires or bars woven, welded, or expanded to form a regular grid with openings. It is widely used for filtration, separation, screening, reinforcement, architectural cladding, and decorative or security applications.

Common forms include woven wire mesh (plain and various weave patterns), welded wire mesh, expanded metal mesh and perforated metal sheets. The meshes differ in opening shape and size and in the way they are manufactured. Materials commonly used include stainless steel, carbon steel, aluminum, brass and copper, as well as specialty alloys. Finishes such as galvanizing, nickel or zinc plating, epoxy coatings, or passivation improve corrosion resistance and life in specific environments.

Manufacturing processes: woven wire mesh is produced by interlacing wires on looms; welded wire mesh by welding wires at intersections; expanded metal by slitting and stretching a metal sheet; perforated metal by punching holes in a sheet. These processes yield products with a wide range of open areas, wire diameters, and tolerances.

Key properties include mechanical strength, dimensional stability, chemical and temperature resistance, and the balance between open area and strength. Selection depends on the application, environment, required filtration or screening performance, and cost. Product types can be tailored with finishes, edge treatments, and sizing to meet industry standards and customer specifications.

Typical applications span filtration and separation, screening and sizing, architectural screens, fencing and security, reinforcement in concrete, acoustical panels, and HVAC or industrial enclosures.
