A Chain link fence is a type of woven fence usually made from galvanized steel wire. The wires run vertically and are bent into a zigzag pattern so that each "zig" hooks with the wire immediately on one side and each "zag" with the wire immediately on the other. This forms the characteristic diamond pattern seen in this type of fence.
Common heights include 3', 42", 4', 5', 6', 7', 8', 10', and 12', though almost any height is possible. Common mesh gauges are 6, 9, and 11. For commercial purposes, 9GA wire is common, although when security is an issue some prefer 6GA because it is harder to cut. 11 gauge wire is usually only used for temporary construction fence.
Chain link is relatively low cost and relatively easy to install. Due to the open weave, chain link offers little privacy. This can be improved by the insertion of slats into the mesh or the installation of screening on the surface.
