A chain link is a metal loop that is typically used to create a fence or a barrier. These links are interlocked to form a continuous chain, providing strength and durability. Chain link fences are popular for both residential and commercial properties due to their visibility and low maintenance requirements. The material used for chain links is often galvanized steel, which helps prevent rust and corrosion. Chain link fencing can be customized in height and gauge, making it suitable for various applications, including security, sports fields, and playgrounds. It is an economical choice for enclosing spaces while allowing airflow and visibility.
