900x1200mm- Class 1 – Aluminium – 80 km Speed Restriction in Roundel

The R4-1C(80) represents top-tier speed limit signage engineered for applications demanding maximum visibility and comprehensive driver awareness. This substantial 900x1200mm regulatory sign displays the 80 km/h speed restriction within the familiar red roundel format, sized to ensure readability from significant distances particularly important on higher-speed roadways where early warning is critical. Manufactured from heavy-duty 1.6mm aluminium alloy and finished with Class 1 high-intensity reflective vinyl, this sign delivers outstanding performance across all environmental and lighting conditions. The larger format proves especially valuable on roads where drivers need substantial advance notice of speed restrictions, enabling safe speed transitions from higher-speed rural roads or highways into more controlled environments. The Class 1 reflective coating utilizes advanced microprismatic technology creating brilliant light return characteristics when illuminated by vehicle headlights, maintaining clarity during nighttime operation, in fog, rain, dust, or when viewed from various approach angles and distances. The aluminium construction ensures exceptional longevity, resisting rust, corrosion, warping, and impact damage while maintaining professional appearance through extended environmental exposure. Weather-resistant graphics and UV-stabilized materials prevent fading ensuring speed limit numerals remain sharp and highly legible throughout the sign’s operational life. Pre-drilled mounting holes enable secure installation on Australian standard sign posts and mounting systems. Full compliance with AS1742 traffic control device standards makes this sign approved for public road use and suitable for private applications requiring regulatory-grade signage.
