Description
The 25km speed roundel communicates moderate-speed zones in residential streets, industrial estates, and mixed-use precincts.

Select aluminium or polypropylene in three standard dimensions: 300×225mm, 450×600mm, or 600×450mm. Add Class 1 or Class 2 reflective finishes for enhanced visibility in low-light conditions.

Frequently asked
Which size is best for a residential street?
The 300×225mm size suits local streets with lower traffic volumes, while 450×600mm works better for busier residential roads or entry points to speed-restricted zones.
Are these signs reflective by default?
Reflective grades provide different visibility performance. Choose the grade required by the project specification and site conditions, and confirm any road, traffic or high-risk requirement with the relevant authority before ordering.
How do I install these on a concrete or timber post?
Pre-drilled holes allow bolt-through or bracket mounting. For concrete, use concrete anchors; for timber, standard wood screws or bolts work well. Installation guides are included with your order.
Do you supply these signs to councils and local governments?
Yes, we work with councils and government bodies on bulk orders. Trade accounts offer invoice payment terms and volume discounts tailored to your procurement schedule.
What's the lead time for a bulk order of 50+ signs?
Automatic volume pricing is 5–9 signs: 8% off, 10–24 signs: 15% off, 25–49 signs: 24% off, 50–99 signs: 32% off, 100+ signs: 40% off. The configurator is the source of truth and updates the unit price as quantity changes.
