600x800mm- Class 1 – Aluminium – 80 km Speed Restriction in Roundel

The R4-1B(80) speed restriction sign delivers effective speed limit communication for moderate to higher-speed road environments. This 600x800mm regulatory sign features the 80 km/h speed limit displayed within the iconic red circular roundel on white background, utilizing universally understood traffic signage design principles recognizable across Australia. Constructed from high-quality 1.6mm aluminium sheeting and laminated with Class 1 high-intensity reflective vinyl, the sign provides excellent visibility during both daytime and nighttime conditions. The Class 1 reflective material incorporates microprismatic technology that captures and returns light from vehicle headlights with exceptional efficiency, ensuring the speed limit remains clearly visible in darkness, fog, rain, and when viewed from various approach angles. The aluminium construction offers outstanding durability, resisting corrosion from environmental exposure, maintaining structural integrity through temperature extremes, and providing resistance to physical impacts from debris and weather events. UV-resistant inks and fade-proof materials ensure the speed limit numerals remain sharp and legible throughout years of outdoor service without color degradation. Pre-drilled mounting holes facilitate straightforward installation on standard sign posts or existing mounting infrastructure for rapid deployment. Full compliance with Australian Standard AS1742 makes this sign appropriate for public road applications as well as private property installations requiring regulatory compliance and professional traffic management. Typical applications include suburban arterial roads, semi-rural collector roads, industrial zone primary access routes, large facility perimeter roads, and transitional zones between rural and urban environments where 80 km/h represents appropriate speed management.
