Product Description
This coastal-grade bridge guardrail is designed for marine and salt-rich environments. It provides superior resistance against chloride-induced corrosion, making it ideal for seaside highways, port bridges, and offshore infrastructure corridors.
Salt particles in coastal air accelerate electrochemical corrosion, rapidly degrading untreated steel structures.
A thick hot-dip galvanized coating combined with optional epoxy top layer provides dual protection against salt spray and humidity.

- Coastal highways
- Seaside bridges
- Port access roads
- Offshore logistics corridors
The dual-layer coating system blocks chloride ions and prevents direct steel exposure, significantly slowing corrosion reaction rates.
- Select epoxy coating for extreme marine exposure
- Use thicker steel for typhoon-prone regions
- Choose thrie-beam for high-speed coastal highways
