Global floating offshore photovoltaic projects expand massively in 2026, steel support piles stay in severe C5-M marine splash zone with long-term seawater immersion, tidal alternation and high-concentration salt fog. Ordinary zinc-rich paint peels within 8–10 years and brings high offshore maintenance costs. FLDC develops exclusive multi-layer marine coating for sea solar piles, fully compliant with ISO 12944 C5-M standard.
Complete floating PV pile coating scheme:

1. High zinc cold spray zinc primer (96% zinc content, instant cathodic protection)
2. High-solid epoxy micaceous iron intermediate coat thick barrier layer
3. Fluorocarbon topcoat with 213 adjustable colors, strong UV & anti-chalking performance
   Core Advantages:
   ✅ Meet ISO 12944 C5-M heavy marine anti-corrosion standard
   ✅ Neutral salt spray test exceed 7000 hours, adapt sea tide wet-dry cycles
   ✅ Cold spray zinc only simple manual derusting, save offshore sandblast cost
   ✅ Flexible film resist wave impact and pile slight deformation
   ✅ 25-year outdoor service life, cut offshore repair frequency drastically
