Ocean Solid Round Buoy Ball

The marine solid round buoy ball is a high-strength polyethylene float with a solid foam-filled structure, designed primarily for water area demarcation, safety marking, aquaculture support, and other marine or inland water applications. Compared to traditional hollow float balls, the solid type offers superior impact resistance, buoyancy reliability, and wave tolerance, making it highly durable for long-term use in harsh environments.

  • EPS Solid Core: Filled with closed-cell expanded polystyrene (EPS) foam at 10–30 kg/m³ density. Maintains buoyancy even if the shell is damaged—much safer than hollow floats.
  • Rotomolded HDPE Shell: Made from high-density polyethylene (HDPE) via one-piece rotational molding. Excellent corrosion resistance and UV durability; lifespan up to 10–15 years.
  • Double Wall with Reinforcement Ribs: Thickened shell with anti-slip texture and circular ribs enhances wave impact resistance by 25%, suitable for sea state 4 conditions.
