Sea-crossing bridges and coastal viaduct steel structures bear ultra-strict long-term anti-corrosion requirements, needing stable protection for decades. The structures are continuously eroded by high-concentration marine salt fog, strong ultraviolet radiation, seasonal typhoon gales and rainwater scouring. Ordinary bridge coatings suffer from rapid aging, fading, cracking and salt corrosion, requiring frequent overhaul and repainting, which increases bridge maintenance costs and affects traffic operation safety.
FLDC ultra-long-life heavy-duty weather-resistant anti-corrosion system for sea-crossing bridge steel structures:
1. High zinc-rich electrostatic anti-rust primer: Fundamental anti-corrosion, prevent steel base oxidation
2. Glass flake dense barrier intermediate coat: Block salt ion and moisture deep penetration
3. Super weather-resistant flexible topcoat: Resist typhoon scouring and long-term UV aging
Core Advantages:
✅ Decade-level long-life protection, adapt sea-crossing bridge long-service requirements
✅ Extreme salt fog resistance, resist perennial marine atmospheric corrosion
✅ Strong typhoon and rain scouring resistance, no peeling under extreme weather
✅ Flexible and crack-resistant, adapt bridge structural micro-deformation
✅ Greatly reduce bridge later maintenance frequency and engineering cost
Widely used in sea-crossing bridges, coastal viaducts and port bridge infrastructure. Request bridge engineering anti-corrosion solutions.
