Basics about chain link mesh you have to know
Chain link fence fabric comes in a variety of gauges. Gauge is the diameter of the wire; the higher the gauge number, the smaller the wire diameter. Common gauges and diameters are as follows:6 gauge=0.192 inch, 9 gauge=0.144 inch, 11 gauge=0.116 inch, 12 gauge=0.106 inch, 12 gauge=0.104 inch
Chain link fabric is available in heights of 36, 42, 48, 60, 72, 84, 96, 120 and 144in. The fabric is formed by weaving a series of spirals together. How the top and bottom of fence is finished is referred to as the selvage. Fences less than 72" must knuckle both ends by industry standard (KK). Heights of 72 and higher are generally twisted or barbed at one end and knuckled (BK) on the other. For high security enclosures, chain link wire mesh can be obtained with both ends twisted or barbed (BB).

Zinc coatings may also differ. There are two different processes for applying zinc to wire. Galvanized after weaving (G.A.W.) is a process in which wire rod is drawn to the finished gauge, then woven into chain link fabric. The fabric is then pulled through a pot of molten zinc. This process applies 1.2 ounces of zinc coating per square foot of fabric and conforms to ASTM standards.
The other process for applying zinc coating to chain link mesh is called galvanized before weaving (G.B.W.). In this process the wire rod is drawn to gauge, and the strand wire is then pulled through a pot of molten zinc. The wire is then woven into chain link fabric. Generally chain link fabric made using this process carries a zinc weight of .8 ounces per square foot or less.
The distance between two parallel wires in the fabric is referred to as the mesh size. The most common mesh sizes are 2 or 2, but smaller meshes of 3/8, 5/8, 1, 1. 1and 1 are available for projects that require a higher degree of security.
