1200x1600mm- Class 1 – Aluminium – 110 km Speed Restriction in Roundel

The R4-1D(110) represents the pinnacle of highway speed limit signage, engineered specifically for high-speed road environments demanding absolute maximum visibility. This substantial 1200x1600mm regulatory sign displays the 110 km/h speed restriction within the universally recognized red roundel format, dimensioned to ensure drivers traveling at maximum highway speeds receive optimal advance notice from extended approach distances. Manufactured from heavy-duty 1.6mm aluminium alloy and finished with Class 1 high-intensity reflective vinyl, this sign delivers exceptional performance in demanding high-speed highway environments across all weather conditions. The extra-large format proves essential on highways where maximum advance warning distance is critical for safety, particularly at locations where speed restrictions commence, at major highway junctions, or where road geometry changes require speed adjustment. The Class 1 reflective material employs advanced microprismatic technology creating exceptional light return characteristics when struck by vehicle headlights at high speeds, maintaining outstanding clarity during nighttime highway operation, in severe adverse weather conditions, and when viewed from very long distances. The aluminium construction ensures superior longevity, resisting corrosion from salt spray and environmental exposure, withstanding severe weather events, and maintaining structural integrity through years of demanding highway service. Premium weather-resistant graphics and UV-stabilized materials prevent fading ensuring speed limit numerals remain crisp and highly legible throughout extended operational life under harsh conditions. Reinforced pre-drilled mounting holes accommodate heavy-duty highway sign posts and mounting systems for secure long-term installation. Full AS1742 compliance makes this sign approved for major national highway use and critical high-speed applications.
