A fence is a structure that encloses an area, typically made of wood, metal, or vinyl. It serves various purposes, such as providing security, marking property boundaries, and offering privacy. Fences can be found in residential yards, farms, and public spaces, and they come in different styles and heights to suit specific needs. In addition to their practical uses, fences can also enhance the aesthetic appeal of a property. Decorative fences, like picket fences, are often used in gardens to create a charming look. Other types, such as chain-link fences, are more utilitarian and are commonly used in commercial settings or to contain pets like dogs.
