Expandable safety barriers are a type of crowd control barrier that can be expanded and contracted to fit a range of different spaces and situations. These barriers are typically made of lightweight and durable materials such as plastic, aluminum, or steel.

The expandable design of these barriers makes them a versatile option for crowd control, as they can be easily adjusted to fit a wide range of different areas, including walkways, entrances, and exits. They are commonly used in retail stores, airports, and other public spaces to control crowds and direct traffic.

Expandable safety barriers can be deployed quickly and easily, making them an ideal solution for emergency situations or situations where rapid deployment is required. They can be folded down into a compact size for easy transport and storage when not in use.
