Overview
Alupanel Traffic Permanent is a substrate engineered specifically for permanent road and highway signage. Constructed with a robust 0.30mm skin bonded to a polyethylene core, it delivers the structural rigidity and surface flatness required for long-term outdoor exposure and reliable reflective film adhesion.
Manufactured in the UK, Alupanel Traffic Permanent provides highway authorities, sign manufacturers, and contractors with a panel they can trust to perform across years of weathering, UV exposure, and mechanical stress. Its high-bond surface ensures that retroreflective sheeting adheres securely and uniformly, maintaining legibility and compliance throughout the installation lifetime.
The 0.30mm skin provides the load resistance and anti-flutter performance required for fixed roadside and gantry installations. Available in a range of standard sheet sizes and thicknesses, it is the trusted choice across the UK road network for directional, regulatory, and warning signs where long-term reliability is non-negotiable.
Key Benefits:
Engineered for permanent vertical road traffic signs
providing specifiers and highway authorities with full confidence in compliance.
0.30mm Aluminium Skin
The heavier skin gauge provides superior structural rigidity and resistance to wind loading and vibration, essential for roadside and gantry-mounted permanent installations.
Premium Reflective Film Bond Surface
The factory-applied paint finish is specifically formulated to achieve optimum adhesion with retroreflective sheeting, ensuring long-term legibility and sign performance.
Proven Outdoor Durability
UV-stable polyester paint finish and corrosion-resistant aluminium construction deliver decades of reliable performance in all weather conditions without delamination or surface degradation.
Manufactured in the UK
British manufacture guarantees consistent quality, rapid availability, and full supply chain traceability, reducing lead times for highway contractors and local authorities.
Cost-Effective Long-Term Value
Superior material quality reduces sign replacement frequency, lowering whole-life costs for highway management and maintenance programmes.
