Spiked fences are barriers designed with sharp points or spikes along the top. They are often used to deter trespassers and enhance security around properties, such as homes, businesses, and government buildings. The spikes can be made from various materials, including metal and plastic, and can vary in height and design. These fences serve both practical and aesthetic purposes. While they provide a physical deterrent against unauthorized entry, they can also contribute to the overall look of a property. However, the use of spiked fences may raise concerns regarding safety and liability, especially in residential areas.
