Tunnel Wall Panels & Boards
Extremely fireproof, moisture-resistant, and highly reflective board solutions for tunnel infrastructure.
Product Systems For Tunnels
For tunnel infrastructure, our solutions primarily focus on high-performance decorative cladding engineered to withstand harsh, confined environments.
Decorative Panels For Tunnels
Highway & Road Tunnels
Engineered with a smooth, fluorocarbon (PVDF) or inorganic coating that effectively resists corrosive vehicle exhaust. The highly reflective surface reduces tunnel lighting costs, and it easily withstands regular high-pressure water jet cleaning.
Utility Tunnels / Trenches
Utility tunnels are permanently damp environments. Our calcium silicate-based decorative panels offer exceptional dimensional stability, preventing warping or rotting in high-humidity conditions, while providing reliable electrical fire containment.
Pedestrian Underpasses
Features an ultra-hard, non-porous finish that makes it difficult for paint or markers to adhere. Graffiti can be wiped away easily with standard solvents, ensuring public underpasses remain clean and structurally sound.
