Chain-Link Fence

A chain-link fence (also referred to as wire netting, chain-wire fence, cyclone fence or hurricane fence) is a type of woven fence usually made from galvanized or LLDPE-coated steel wire. The wires run vertically and are bent into a zig-zag 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.

A perimeter fence is a structure that circles the perimeter of an area to prevent access. These fences are frequently made out of single vertical metal bars connected at the top and bottom with a horizontal bar. They often have spikes on the top to prevent climbing. . Some fences may be string-like pieces of metal stretching across horizontally and vertically, creating a mesh of metal.
