600x800mm- Class 1 – Aluminium – 70 km Speed Restriction in Roundel

The R4-1B(70) speed restriction sign communicates 70 km/h speed limits through proven regulatory signage design principles. This 600x800mm sign displays the speed limit within the familiar red circular roundel format providing instant recognition for all motorists. Manufactured from premium 1.6mm aluminium sheeting and finished with Class 1 high-intensity reflective vinyl, the sign delivers reliable performance in all environmental conditions. The Class 1 reflective coating utilizes advanced microprismatic technology to reflect vehicle headlights with exceptional efficiency, ensuring the speed limit remains clearly visible during nighttime operation and in poor weather conditions including rain, fog, and dust accumulation. The aluminium construction provides excellent durability, resisting rust, corrosion, and degradation from prolonged exposure to sun, rain, and industrial environments. UV-resistant inks and weatherproof laminates ensure the graphics remain sharp and fade-free through years of outdoor service without requiring replacement. Pre-drilled mounting holes enable straightforward installation on standard Australian sign posts or existing infrastructure for quick deployment. Compliance with Australian Standard AS1742 makes this sign suitable for both public road applications and private property where regulatory signage standards apply and professional traffic management is required. Typical applications include semi-rural roads approaching urban areas, industrial estate collector roads, large facility access routes, and suburban roads where 70 km/h provides appropriate speed management for prevailing conditions.
