What is an expandable safety barrier?
An expandable safety barrier is a portable or fixed retractable barrier designed to quickly restrict access to hazardous or restricted areas.
Its expandable “accordion-style” design allows the barrier to:
Extend when an area needs to be isolated
Collapse compactly when access is restored
Why use an expandable barrier instead of cones or tape?
Cones and tape provide visual warnings only, while an expandable barrier creates a physical and highly visible restriction.
How do I know which size to order?
Measure the full width of the opening you want to close off when the barrier is extended, and the height clearance you need. We stock 12 combinations across three heights (1000 mm, 1500 mm, 2000 mm) and four extended lengths (3 m, 4 m, 5 m, 6 m). Choose a length that matches or slightly exceeds your opening — the barrier can always be extended less than its maximum. If your opening is between sizes, go up to the next length so you have a secure latch point on the far side. Not sure? Give us a call, and we'll help you get it right the first time.
Can expandable barriers be overextended?
Yes, expandable barriers can be overextended beyond the advertised length, but doing so will cause a reduction in the final height of the barrier.Like all accordion-style barriers, the scissor geometry means the bottom rail sits above floor level, and this gap increases slightly as the barrier extends further.
Can I connect two barriers together to cover a wider opening?
Yes, and this is a popular setup for wide roller doors or warehouse bays. Contact our team to discuss the best way to join units for your specific opening — the approach depends on the wall or post configuration at the centre join point. For very wide spans, we can also advise on whether a pair of barriers opening from a central post is better than a single long run.
Can this barrier stops a forklift?
No — the expandable barrier is designed for pedestrian access control, not vehicle impact. It creates a clear visual and physical signal to stop people from walking into a restricted zone, but it is not rated to withstand a forklift or vehicle collision. If you need protection against moving machinery, our range of impact-rated bollards and warehouse guardrail is the appropriate solution. The two work well together: bollards to absorb vehicle impact, expandable barriers to manage pedestrian flow in the same area.
Does using an expandable barrier help with workplace health and safety compliance?
Yes. Under New Zealand's Health and Safety at Work Act 2015, employers have a duty to manage risks to workers and others in the workplace. Clearly demarcating hazardous or restricted zones is a recognised control measure. An expandable barrier creates an unambiguous physical and visual boundary that supports your site's traffic management plan, particularly in mixed pedestrian-vehicle environments. It won't replace a full traffic management assessment, but it is a practical, low-cost control that auditors and WorkSafe inspectors regularly see as evidence of active hazard management.
