![]() You'll also find aluminum-coated (aluminized) wire on the market. GAW ensures that all of the wire is coated, even the cut ends, and galvanizing the wire after it is formed also tends to increase the tensile strength of the finished product. There is some debate over which is the best method. The alternative is Galvanized Before Weaving (GBW), where the strand of wire is coated with zinc before being formed into the mesh. The most common is Galvanized After Weaving (GAW), where the steel wire is formed into chain link fabric first and then galvanized. There are two primary ways that chain link fabric is galvanized or coated with zinc. As you might expect, the longevity of the protective coating is directly related to the amount of zinc that is applied. For specification projects requiring greater degrees of longevity, two-ounce coatings are available. Typically, galvanized chain link fabric has a 1.2-ounce per square foot zinc coating. 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. In other words, it dissipates while protecting the steel. As we mentioned previously, the most common protective coating for chain link fabric is zinc. Several types of surface treatments help protect and beautify steel chain link fabric. Smaller meshes such as 1 3/4-inch are common for tennis courts, 1 1/4-inch for pools, and high-security mini meshes of 5/8-inch, 1/2-inch, and 3/8-inch are also available. The smaller the diamond, the more steel is in the fabric.įrom largest to smallest, typical mesh sizes are 2 3/8-inch, 2 1/4-inch, and two-inch. Mesh size tells you how far apart the parallel or diamond shape wires are in the fabric, and it's another indication of how much steel is in the product. Six-gauge is typically for heavy industrial or specialized uses, and the lighter gauges are best suited for temporary fencing. Unless you are building a temporary fence, choose fencing between 11-1/2 and nine-gauge. ![]() The smaller the gauge number, the more steel, the higher the quality, and the stronger the wire.įrom lightest to heaviest, common gauges are 13, 12-1/2, 11-1/2, 11, nine, and six. This helps tells you how much steel is actually in the fabric. Gauge or diameter of wire is one of the most important factors. Select your chain link fence fabric based on these three criteria: gauge of wire, size of mesh, and type of protective coating. Choosing Materials for a Chain Link Fence They'll also give your chain link even more protection against corrosion or rust. These color treatments enhance landscaping and blend naturally with trees, shrubs, and bushes. The most common coating is zinc (galvanized), but you'll also find chain link components with vinyl or polyester color coatings in addition to zinc. Each of these components is available in a range of weights (gauges) and types of protective coatings. ![]()
