For the structure pattern in chemistry, see Chicken wire (chemistry) Chicken wire, or poultry netting, is a mesh of wire commonly used to fence in fowl, such as chickens, in a run or coop. It is made of thin, flexible, galvanized steel wire with hexagonal gaps. Available in 1⁄2 inch (about 1.3 cm), 1 inch (about 2.5 cm) diameter, and 2 inch (about 5 cm), chicken wire is available in various gauges—usually 19 gauge (about 1 mm wire) to 22 gauge (about 0.7 mm wire). Chicken wire is occasionally used to build inexpensive pens 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 or hardware cloth is used as a metal lath to hold cement or plaster, a process known as stuccoing. Concrete reinforced with chicken wire or hardware cloth 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.
History [ edit ] Charles Barnard, a British ironmonger, built the world's first wire-netting machine in 1844. He based his design on cloth weaving machines. Soon the firm of Barnard, Bishop & Barnard, established in Norwich, was selling wire netting all over the world. [1]
During World War II, the fine wire used to make chicken wire was used to make large wire ground mats for radar systems, evening out the random reflections from the uneven ground below. The installation of these systems caused a countrywide shortage of chicken wire in the United Kingdom.[2]
During World war II it was also commonly put on helmets by German soldiers to cover the helmet and camouflage it with plants and branches.
Other uses [ edit ] In chemistry, molecules with fused carbon rings are often compared to chicken wire — see chicken wire (chemistry).
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.
Chicken wire is sometimes used to provide grip on surfaces such as wooden steps or decking.
Chicken wire commonly used in construction has been found to block or attenuate Wi-Fi, cellular and other radio frequency transmissions by inadvertently creating a Faraday cage.[3]

Application of plaster mesh
Plaster mesh helps to form the internal skeleton layers of plaster and putty. In differences of temperature and humidity, under a mechanical stress, plaster mesh will provide excellent protection for the plastering layer area. Plaster mesh makes it has a high resistance to wear and able to withstand heavy loads .
Plaster mesh normally used for internal and external plastering, it also actively used in the production of self-leveling floors, installation of thermal insulation and acoustic insulation materials, waterproofing, separation of heterogeneous layers and the junction of the walls doorframes. Plastering mesh used to protect the facades of buildings and structures. Plastic and fiberglass mesh are also perfectly used for places where the window and door frames are connected to the wall, and the wall adjacent to the floor or ceiling.
Types of plaster mesh
There are many types of plaster mesh: Galvanized chicken wire, welded wire mesh, light type expanded metal, chain wire mesh, fine woven wire mesh, fiberglass cloth, and plastic netting.
Various types of plastering mesh have different mechanical and physical properties. Based on this, and it is worth buying a particular type mesh - suitable for a particular work.
We will tell you how to choose a suitable plastering mesh, list as below.
Reinforcing plaster mesh is perfectly suited for the reinforcement and restoration of existing plaster and brickwork.
Fiberglass plaster mesh with mesh size 5 × 5mm and mesh density 165g/sq.m
Light type plaster expanded metal sheet in a roll
Fiberglass cloth mesh is made of glass fiber, and then impregnated with an alkaline dispersion - increased resistance to tearing. It has high reliability, durability and longevity . It is very effective when using quick- dry finishing mixtures.
Very important indicator of this mesh is its surface density. For example, a front wall mesh varies in the range from 165 to 300g/sq.m. Maximally dense mesh used on the lower floors, as in this case a very high risk of both natural and intentional damage to the front elevation. A plaster mesh with a density in the range of 110 to 160g/sq.m. is fine for internal construction and finishing work. Masking fiberglass mesh for reinforce walls before painting the walls or for putty works, its mesh opening needs extremely small.
The mesh performance depends not only on the material and size, but the mesh opening shape.
Light type expanded metal with diamond hole shape is almost indispensable for plastering work. Its diamond shape holes allow maximum grip to plaster layer. Due to the excellent characteristics, it is frequently used for installation of underfloor heating.
Welded wire mesh manufactured by welding rods perpendicular to the wire is also used in the manufacture of plaster works, but somewhat less than expanded metal. It is often used in the production of fences and cages in poultry and livestock.
Metal plaster mesh has a different coefficient of linear thermal expansion with plaster layer. With twist woven structure and hexagonal shape mesh, chicken wire is sufficiently acceptable for plastering better than rigid mesh - welded wire mesh and expanded metal. Due to its flexibility unimaginable property, chicken mesh is quite convenient to attach to various angular and curved surfaces.
