Chain Link Fence link fence chain link, chain fence
Chain-link has four elements: fabric, framework, fittings and gates.
Chain-link fabric
From lightest to heaviest, common gauges are 13, 12-1/2, 11-1/2, 11, 9 and 6. Unless you are building a temporary fence, I would recommend fencing between 11-1/2 and 9 gauge. 6 gauge is typically for heavy industrial or specialized uses and the lighter gauges are best suited for temporary fencing.
Measure the mesh
The smaller the diamond, the more steel is in the fabric. From largest to smallest, typical mesh sizes are 2-3/8", 2-1/4" and 2". Smaller meshes such as 1-3/4" for tennis courts, 1-1/4” for pools and high-security mini meshes of 5/8", 1/2" and 3/8" are also available.
Consider the coating
The most common protective coating for chain-link fabric is zinc. Zinc is a self-sacrificing element. It also offers cathodic protection, which means that if the wire is cut, it "heals" the exposed surface by developing a white oxidation layer that prevents red rust. Typically, galvanized chain-link fabric has a 1.2-ounce per square foot coating. For specification projects requiring greater degrees of longevity, 2-ounce zinc coatings are available. The longevity of the protective coating is directly related to amount of zinc that is applied.
Fabric should meet these specifications
The following ASTM specifications apply to chain-link fence fabric:
Specification for Zinc Coated Chain-Link Fence Fabric (A 392-96)
Specification for Zinc-5% Aluminum-Mischmetal Alloy Coated Chain-Link Fence Fabric (Galvinal) (F 1345-96)
Specification for Polyvinyl Chloride Coated Steel Chain-Link Fences (F 668-96)
Decide on the diameter
Typical diameters are 1-3/8", 1-5/8", 1-7/8", and 2-3/8" for residential fences. ASTM makes the following recommendations for residential chain-link fence framework.

Polyvinyl chloride (PVC) and polyester color coatings can supplement the metallic protective coatings described above. You'll gain an additional defense against corrosion, and add aesthetics to blend with the environment. Standard colors are black, brown and green.
PVC is applied to the framework in a thickness of 10 to 14 mils -
Polyester coating is a 3-mil color powder that is electro-statically applied.
Framework should meet these specifications
The following ASTM specifications apply to framework:
Specification for Strength Requirements of Steel Posts and Rails for Residential Chain-Link Fence 1992 (F 761-82)
Specification for Stand Colors for Polymer-Coated Chain-Link Fence (F 934-96)
Fittings
All steel fittings such as bands, tension bars, nuts and bolts, and gate hardware must be hot-dip galvanized to prevent corrosion with similar coatings as with the framework and fabric. While there are ASTM specifications on fittings,
