Guard Rails
Guard rails, often referred to as safety barriers or guard fences, are structures designed to prevent vehicles, pedestrians, or other objects from inadvertently entering into a dangerous or restricted area. Guard rails are commonly used in transportation infrastructure, construction sites, and various industrial settings to enhance safety.
Guard rails play a crucial role in maintaining safety and preventing accidents in various settings. Their design and specifications may vary based on regional standards, the type of roadway or area they protect, and the potential hazards they are meant to address.
