Mesh consists of semi-permeable barrier made of connected strands of metal, fiber, or other flexible/ductile material. Mesh is similar to web or net in that it has many attached or woven strands.
Types of mesh:
A plastic mesh is extruded, oriented, expanded or tubular. Plastic mesh can be made from polypropylene, polyethylene, nylon, PVC or PTFE.
A metal mesh can 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
Uses of mesh:
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.
A huge quantity of mesh is being used for screen printing work.
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.
