Expandable barriers typically extend to 2-4 metres when fully open. Larger heavy-duty models can extend to 8 metres or more. The compact folded size makes them easy to store and transport, and they can be deployed by a single person in seconds.

Are expandable barriers suitable for outdoor use?

Yes. Most expandable barriers are manufactured from UV-stabilised plastic or powder-coated steel and are suitable for outdoor use in all UK weather conditions. Rubber feet prevent slipping on wet surfaces. For exposed outdoor use, consider securing the base to prevent wind displacement.
