900x1200mm- Class 1 – Aluminium – 110 km Speed Restriction in Roundel

The R4-1C(110) delivers highway-grade speed limit communication through substantial dimensions and professional construction. This 900x1200mm regulatory sign displays the 110 km/h speed restriction within the iconic red roundel format, sized specifically for high-speed road environments where readability at distance is essential for driver compliance. Manufactured from heavy-gauge 1.6mm aluminium alloy and laminated with Class 1 high-intensity reflective vinyl, this sign maintains exceptional visibility across all highway operating conditions. The larger format ensures drivers traveling at high speeds have adequate time and distance to perceive and comprehend the speed limit. The Class 1 reflective coating employs microprismatic technology creating brilliant light return when illuminated by vehicle headlights at highway speeds, maintaining sign clarity during nighttime high-speed operation, in adverse weather including fog, rain, and dust conditions, and when viewed from extended approach distances. The aluminium construction provides outstanding durability, resisting corrosion from environmental exposure including salt spray and moisture, maintaining structural integrity through extreme temperature variations, and withstanding impact from debris. Weather-resistant inks and UV-stabilized materials ensure the speed limit numerals remain sharp and highly legible throughout years of continuous highway service exposure. Pre-drilled mounting holes facilitate secure installation on standard Australian highway sign posts and mounting systems. Full compliance with AS1742 traffic control device standards makes this sign approved for public highway use and suitable for private roads requiring regulatory compliance. Typical applications include national highways, major state roads, rural highway sections, and private roads where 110 km/h represents the legal speed limit and professional traffic management is required.
