metalliverkkoja

Metalliverkkoja is the Finnish term for metal meshes or lattice structures made from metal wires or strips arranged in a regular pattern. These meshes are produced in various configurations and are used across industries for reinforcement, filtration, separation, screening, and architectural or decorative purposes.

Common materials for metalliverkkoja include carbon steel, stainless steel, aluminum, copper, and brass. Finishes such as galvanization, powder coating, anodizing, or electroplating are often applied to improve corrosion resistance or appearance. Production methods vary: welded wire mesh joins intersecting wires by welding, woven wire mesh interlaces warp and weft wires, expanded metal mesh is created by slitting and expanding a metal sheet, and perforated metal uses punched holes to form a mesh-like pattern. Knitted, braided, or hybrid meshes also exist for specialized applications.

Main types of metalliverkkoja include welded wire mesh, which provides rigid panels for reinforcement or fencing; woven wire mesh, known for flexibility and uniform openings; expanded metal mesh, which offers a strong, lightweight lattice with a diamond or rectangular opening; and perforated metal sheets, which create a decorative or filtration-ready grid through punched patterns. Each type is chosen based on opening size, wire thickness, strength requirements, and environmental conditions.

Typical applications range from concrete reinforcement and boundary fencing to filtration, screening in mining and food processing, acoustical and architectural screens, and EMI/RFI shielding in electronics. Design considerations include aperture size, wire diameter, material and finish, load requirements, and exposure to corrosion. Standards and specifications vary by region, but metalliverkkoja products are generally designed for interoperability with common construction and industrial practices. Recycling and sustainability are considered in material choice and end-of-life handling.
