1200x1600mm- Class 1 – Aluminium – 100 km Speed Restriction in Roundel

The R4-1D(100) represents the premium tier of highway speed limit signage, engineered for applications demanding absolute maximum visibility and advance warning distance. This substantial 1200x1600mm regulatory sign displays the 100 km/h speed restriction within the universally recognized red roundel format, dimensioned to ensure drivers traveling at highway speeds receive maximum advance notice from extended distances. Manufactured from heavy-duty 1.6mm aluminium alloy and finished with Class 1 high-intensity reflective vinyl, this sign delivers exceptional performance in the most demanding highway environments. The extra-large format proves essential on high-speed roads where drivers need maximum advance warning, particularly at locations where speed restrictions begin, at highway intersections, or where road conditions change. The Class 1 reflective material employs state-of-the-art microprismatic technology creating brilliant light return characteristics when struck by vehicle headlights, maintaining outstanding clarity during nighttime high-speed operation, in severe adverse weather including heavy rain and fog, and when viewed from extended distances or oblique angles. The aluminium construction ensures exceptional longevity, resisting corrosion, severe weather damage, and impact from debris while maintaining professional appearance through years of harsh highway exposure. Premium weather-resistant graphics and UV-stabilized materials prevent fading ensuring speed limit numerals remain sharp and highly legible throughout extended operational life. Reinforced pre-drilled mounting holes accommodate heavy-duty Australian highway sign posts and mounting systems for secure long-term installation. Full AS1742 compliance makes this sign approved for major highway use and critical high-speed applications requiring maximum visibility and regulatory compliance.
