Curious about HDPE floating fish cages? Learn about their main benefits and farming capacity.

The diameter measured from the central axis of the inner pipe is 15 m, with a circumference of 47.1 m. The spacing between each bracket is approximately 1.67 m, and the water covering area is around 177 sq.m. Unit price: USD 22 per sq.m.
| Items | Specification |
|---|---|
| Main Float Pipe | Φ 250 mm OD × 11.9 mm wall thickness, SDR21 |
| Handrail Pipe | Φ 110 mm × 10 mm, SDR11 (thickened) |
| Bracket | Simplified single-post |
| Frame Material | High-density PE100 pipe, anti-aging and UV-resistant |
| Buoyancy System | Integrated high-buoyancy PE float modules. Suitable for 6 m to 15 m water depth in lakes and reservoirs |
| Anti-Wave Grade | Designed for significant wave heights up to 3 m, class 10 monsoon resistant, suitable for most lake areas |
| Design Drawing | See pictures below |
| Unit Price (EXW Dongguan, China) | USD 4,000 / unit |
| MOQ | 5 units (available for trial) |
| Lead Time | 7–10 working days after deposit |

| Feature | 15 m HDPE Circular Cage | Traditional Galvanized Steel Cage |
|---|---|---|
| Initial Framework Cost | Around $4,000 USD only | Significantly higher total budget needed to build 14 separate units |
| Total Farming Water Volume | ~1,060 m³ (spacious, all-in-one modern aquaculture system) | ~1,050 m³ (split into 14 separate, cramped boxes) |
| Single Cage Specification | Diameter: 15 m (net depth: 6 m) | 5 m × 5 m (net depth: 3 m) |
| Lifespan & Maintenance | 15–25 years (premium high-density material, ultra-long anti-aging life) | 1–3 years (welds crack under waves, metal rusts quickly, oil drums leak constantly) |
| Labor & Management Cost | Ultra-low (1 feeding zone, simple 1-net cleanup, highly efficient) | High (workers must row between 14 separate nets to clean and feed) |
| Site Adaptability | Deep waters, open sea, lakes & reservoirs (high oxygen exchange, faster fish growth) | Shallow near-shore stagnant waters (high risk of mass mortality due to low oxygen) |

To ensure your trial runs smoothly, we provide complete after-sales support:
If you share your farm's specific location and conditions, we can also adjust the cage design to better fit your environment.

It was a pleasure to receive our international partners for a full factory visit. We demonstrated our patented brackets, anti-wave fish cages, and full line of farming nets, plus live load tests that meet universal aquaculture standards. We shared tailored technical proposals and anticipate lasting, mutually beneficial cooperation across the globe.
