Frequently asked questions
Why is the roundel design preferred for speed limits?
The circular format is instantly recognisable and meets international traffic sign conventions, making it effective even when viewed at an angle or from a distance.
What's the typical installation height for this sign?
For optimal visibility, mount at eye level (1.5–2 m high) on posts or walls, ensuring the sign face is perpendicular to the direction of travel.
Is Class 1 reflective material sufficient for daytime use?
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.
Can I mix materials in a bulk order?
