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

Types of mesh[edit]

  • 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, a mesh is often defined as a loosely woven or knitted fabric that has a large number of closely spaced holes, 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 is used to create new products such as tape and filters. When it is used as a filter, it is not uncommon for the manufacturer to spray a PVC coating to make it stronger and last longer. The most common place to find fiberglass mesh is in tape products.

Uses of mesh[edit]

  • Meshes are often used to screen out unwanted things, such as insects. Wire screens on windows and mosquito netting can be considered as types of 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 also used as drum heads in practice and electronic drum sets.
  • Fence for livestock or poultry (chicken wire or hardware cloth)
  • Humane animal trapping now use woven or welded wire mesh cages (chicken wire or hardware cloth) to trap wild animals in domestic areas, such as raccoons, skunks, etc.
