900x1200mm- Class 1 – Aluminium – 70 km Speed Restriction in Roundel

The R4-1C(70) provides commanding speed limit communication through substantial dimensions and premium construction materials. This 900x1200mm regulatory sign displays the 70 km/h speed restriction within the universally recognized red roundel format, engineered to ensure drivers receive adequate advance warning when transitioning from higher-speed zones to more controlled environments. Manufactured from robust 1.6mm aluminium alloy with Class 1 high-intensity reflective vinyl laminate, this sign maintains exceptional visibility regardless of lighting conditions or weather challenges. The larger format proves essential on roads where advance speed communication enables safer vehicle speed transitions, particularly on routes where traffic flows from highway speeds into more controlled environments requiring gradual speed reduction. The Class 1 reflective technology features microprismatic elements that create brilliant light return when struck by vehicle headlights, maintaining sign clarity during nighttime driving, in adverse weather, and when viewed from oblique angles. The aluminium substrate delivers superior longevity, resisting corrosion, physical damage, and environmental degradation while maintaining structural integrity and professional appearance through extended service life. Weather-resistant graphics and UV-stable materials prevent fading ensuring speed limit numerals remain crisp and highly legible throughout years of continuous operation. Pre-drilled mounting holes accommodate standard Australian traffic sign mounting systems for secure compliant installation. Full AS1742 compliance makes this sign approved for public road use and suitable for private applications requiring regulatory-grade signage and professional traffic management solutions.
