Chicken wire
Encyclopedia
Chicken wire, or poultry netting, is a mesh
of wire
commonly used to fence
poultry livestock. It is made of thin, flexible galvanized wire, with hexagonal gaps. Available in 1 inch (about 2.5 cm) diameter, 2 inch (about 5 cm) and 1/2 inch (about 1.3 cm), chicken wire is available in various wire gauges usually 19 gauge (about 1 mm wire) to 22 gauge (about 0.7 mm wire). Chicken wire is occasionally used to build spacious yet inexpensive cages for small animals (or to protect plants and property from animals) though the thinness and zinc
content of galvanized wire may be inappropriate for animals prone to gnawing and will not keep out predators.
In construction, chicken wire is used as a matrix to hold cement or plaster, in a process known as stucco
ing. Concrete reinforced with chicken wire yields ferrocement
, a versatile construction material. It can also be used to make the armature for a papier-mâché
sculpture, when relatively high strength is needed.
It can also be used as a security measure in musical venues to protect the musicians from things being thrown at them, as seen in the 1980 film The Blues Brothers

In photonics
, the chicken-wire effect is a predominant pattern of low transmission lines between multifiber bundles in a fiberoptic used to couple the intensifier tube to the CCD
sensor. The lines have a pattern similar to that of chicken wire.
In machine tool design, chicken wire may be used for safety guarding.

Mesh
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:...

Wire
A wire is a single, usually cylindrical, flexible strand or rod of metal. Wires are used to bear mechanical loads and to carry electricity and telecommunications signals. Wire is commonly formed by drawing the metal through a hole in a die or draw plate. Standard sizes are determined by various...

Fence
A fence is a freestanding structure designed to restrict or prevent movement across a boundary. It is generally distinguished from a wall by the lightness of its construction: a wall is usually restricted to such barriers made from solid brick or concrete, blocking vision as well as passage .Fences...

Zinc
Zinc , or spelter , is a metallic chemical element; it has the symbol Zn and atomic number 30. It is the first element in group 12 of the periodic table. Zinc is, in some respects, chemically similar to magnesium, because its ion is of similar size and its only common oxidation state is +2...
