A chain-link fence (also referred to as wire netting, wire-mesh fence, chain-wire fence, cyclone fence, hurricane fence, or diamond-mesh fence) is a type of woven fence usually made from galvanized or linear low-density polyethylene-coated
In the United Kingdom, the firm of Barnard, Bishop & Barnards was established in Norwich to produce chain-link fencing by machine. The process was developed by Charles Barnard in 1844 based on cloth weaving machines (up until that time, Norwich had a long history of cloth manufacture).
The Anchor Post Fence Co. bought the rights to the wire-weaving machine and was the first company to manufacture chain-link fencing in the United States. Anchor Fence also holds the first United States patent for chain-link. The machine was purchased from a man in 1891 from Belgium, who originally invented the wire bending machine.
In the United States, fencing usually comes in or rolls, which can be joined by "unscrewing" one of the end wires and then "screwing" it back in so that it hooks both pieces. Common heights include one-foot increments from to , and other heights including , , and although almost any height is possible. Mesh is commonly 9, 11, or wire gauge. Mesh length can also vary based on need, with the standard diamond size being .
For tennis courts and ballparks, the most popular height is . Tennis courts often use a diamond size of , as measured flat side to flat side, so that power hitters cannot lodge the ball in the fence.
The popularity of chain-link fence is from its relatively low cost and that the open weave does not obscure sunlight from either side of the fence. A chain-link fence can be made semi-opaque by using

Development of chain-link fencing
In the United Kingdom, the firm of Barnard, Bishop & Barnards was established in Norwich to produce chain-link fencing by machine. The process was developed by Charles Barnard in 1844 based on cloth weaving machines (up until that time, Norwich had a long history of cloth manufacture).

The popularity of chain-link fence is from its relatively low cost and that the open weave does not obscure sunlight from either side of the fence. A chain-link fence can be made semi-opaque by using fence insert
A fence insert is an object designed to fit or clip into standard chain link fencing. There are three main objectives typically fulfilled by fence inserts. One is to provide privacy by converting chain link fencing into an opaque surface. Another i ...

Installation
The installation of chain-link fence involves setting posts into the ground and attaching the fence to them. The posts may be steel tubing, timber or concrete and may be driven into the ground or set in concrete. End, corner or gate posts, commonly referred to as "terminal posts", must be set in concrete footing or otherwise anchored to prevent leaning under the tension of a stretched fence. Posts set between the terminal posts are called "line posts" and are set at intervals not to exceed 10 feet. The installer attaches the fence at one end, stretches it, and attaches at the other, easily removing the excess by "unscrewing" a wire. In many cases, the installer stretches a bottom tension wire, sometimes referred to as "coil wire", between terminal posts to help minimize the in and out movement that occurs at the bottom of the chain-link mesh between posts. Top horizontal rails are used on most chain-link fences, although not necessary if the terminal posts are braced correctly. A top tension wire may be used in this situation. Bottom rails may be added in lieu of bottom tension wires, and for taller fences, 10 feet or more, intermediate horizontal rails are often added. Finally, the installer ties the fence to the line posts and rails with steel or aluminum wire with a hook on one end called “fence ties”. The bottom tension wire should be secured to the line posts and the chain-link mesh "hog ringed" to the tension wire 2' on center.Manufacturing
The manufacturing of chain-link fencing is called weaving. A metal wire, often galvanized to reduce corrosion, is pulled along a rotating long and flat blade, thus creating a somewhat flattenedspiral
In mathematics, a spiral is a curve which emanates from a point, moving farther away as it revolves around the point.
Helices
Two major definitions of "spiral" in the American Heritage Dictionary are:double helix. One of the spirals is woven through the last spiral that is already part of the fence. This improvement allows the process to advance twice as fast.Chain link weaving machine - video
