Metal barricades are sturdy physical barriers used to control crowds, secure areas, or direct traffic. Made from durable materials like steel or aluminum, they offer strength and stability. Commonly used at events, construction sites, or during emergencies, they can be easily assembled and disassembled. Many designs are portable and stackable, often featuring reflective surfaces or signage for increased visibility. Their versatility makes them ideal for both temporary and long-term applications in managing public safety and ensuring orderly flow.
