600x800mm- Class 1 – Aluminium – 60 km Speed Restriction in Roundel

The R4-1B(60) speed restriction sign provides essential speed limit communication optimized for moderate-traffic environments. This 600x800mm regulatory sign displays the 60 km/h speed limit within the universally recognized red circular roundel on white background, ensuring immediate comprehension by all motorists. Manufactured from robust 1.6mm aluminium sheeting with Class 1 high-intensity reflective vinyl laminate, the sign maintains excellent visibility throughout day and night operation. The reflective coating features honeycomb microprismatic pattern that captures and returns light from vehicle headlights at wide angles, ensuring the speed limit remains clearly visible even when drivers approach from oblique angles or in challenging weather conditions. The aluminium substrate offers exceptional durability, resisting corrosion from salt, moisture, and industrial pollutants while maintaining structural integrity through temperature extremes and weather exposure. UV-resistant inks and fade-proof materials ensure the speed limit numerals remain crisp and legible for years of outdoor service without deterioration. Pre-drilled mounting holes enable straightforward installation on standard posts or brackets. Full compliance with Australian Standard AS1742 makes this sign suitable for public road applications and private property where regulatory compliance is essential and professional traffic management is required.
