There are many reasons why property owners like getting chain link fences to enclose their backyards. For one, they are among the cheapest types of fencing material available, so if budget is an issue there is always this option that you can run to. Chain link fences are also pretty strong, especially those that use thicker galvanized materials, so they are perfect for keeping dogs in and any stray animals out.
Most chain link fences nowadays are generally longer lasting compared to other types of materials and are resistant from rust and corrosion. There is no maintenance needed for these types of fences, making them perfect for gardens and sports courts as well as locations needing a temporary or boundary fence. If privacy is a concern, mesh or slats could always be added to a standard chain link fence.
