Bangkok Expressway and Metro applied Rust-Oleum 9100, 9300, and 9400 series industrial coatings to safeguard both interior and exterior steel structures across its infrastructure network. This included corrosion protection for steel frameworks in above-ground areas as well as tunnel environments within the underground metro system. The coating systems were selected for their strong adhesion, long-term durability, and resistance to harsh urban conditions.

In addition, Denso anti-corrosion tape was used to wrap underground piping systems, providing a reliable moisture barrier and mechanical protection against soil and environmental exposure. Together, these solutions support the long-term integrity of Bangkok’s critical transit infrastructure, minimizing maintenance needs and ensuring continuous, safe operation.
