A chain-link fence is a type of fencing made from interwoven steel wires that create a diamond pattern. It is commonly used for security and boundary purposes in residential, commercial, and industrial settings. The fence is typically supported by metal posts and can be coated with vinyl or galvanized to prevent rusting. These fences are popular due to their durability, low maintenance, and visibility. They allow light and air to pass through while providing a clear boundary. Chain-link fences can also be customized in height and color, making them versatile for various applications, including enclosing yards, parks, and sports fields.
