A mesh is a barrier made of connected strands of metal, fiber, or other flexible or ductile materials. A mesh is similar to a web or a net in that it has many attached or woven strands.

Types

  • A plastic mesh may be extruded, oriented, expanded, woven[1] or tubular. It can be made from polypropylene, polyethylene, nylon, PVC or PTFE.
  • A metal mesh may be woven, knitted, welded, expanded, photo-chemically etched or electroformed (screen filter) from steel or other metals.
  • In clothing, mesh is loosely woven or knitted fabric that has a large number of closely spaced holes. Knitted mesh is frequently used for modern sports jerseys and other clothing.
  • A mesh skin graft is a skin patch that has been cut systematically to create a mesh. Meshing of skin grafts provides coverage of a greater surface area at the recipient site, and also allows for the egress of serous or sanguinous fluid. However, it results in a rather pebbled appearance upon healing that may ultimately look less aesthetically pleasing.[2]
  • Fiberglass mesh[3] is a neatly woven, crisscross pattern of fiberglass thread that can be used to create new products such as door screens, filtration components, and reinforced adhesive tapes. It is commonly sprayed with a PVC coating to make it stronger, last longer, and to prevent skin irritation.

Uses

  • Meshes are often used to screen out insects. Wire screens on windows and mosquito netting are meshes.
  • Wire screens can be used to shield against radio frequency radiation, e.g. in microwave ovens and Faraday cages.
  • Metal and nylon wire mesh filters are used in filtration.
  • Wire mesh is used in guarding for secure areas and as protection in the form of vandal screens.
  • Wire mesh can be fabricated to produce park benches, waste baskets and other baskets for material handling.
  • Woven meshes are basic to screen printing.
  • Surgical mesh is used to provide a reinforcing structure in surgical procedures like inguinal hernioplasty, and umbilical hernia repair.
  • Meshes are used as drum heads in practice and electronic drum sets.
  • Fence for livestock or poultry (chicken wire or hardware cloth)
  • Humane animal trapping uses woven or welded wire mesh cages (chicken wire or hardware cloth) to trap wild animals like raccoons and skunks in populated areas.
  • Meshes can be used for eyes in masks.
