Whether the fence is made of steel with a protective layer of zinc or vinyl, chain link fences can last decades, and withstand brutal weather and other elements, like the constant onslaught of abuse from children and animals.
Even in the worst-case scenario, if a car drives through your fence, or a tree crushes a section of it, you will be surprised at how little damage results, and how quickly the damaged section can be repaired.
Chain link fences make the lives of intruders pretty difficult. When high enough, they are difficult to climb, and specialized tools would be needed to cut through the strong steel chains. Chain link fences are also perfect to keep wild animals out, and your pets and children in. The security of your most valuable possessions can be trusted.
