Structural features

Circular Cage

Used in offshore, lakes and reservoirs, suitable for small circular cages with a circumference of less than 60 meters.

  • Marine-specific HDPE materialGreen and environmentally friendly, 100% recyclable, with the advantages of high strength, high toughness, oxidation resistance, acid and alkali resistance, and impact resistance.
  • Simple and solid structure, small resistance coefficientIt has strong wind and wave resistance and can withstand level 12 typhoons and 6m waves.
  • Wide range of applicationIt can be installed in oceans, rivers, lakes, reservoirs and other waters with water depths from -6m to -50m.
  • Investment cost is relatively lowIt occupies a large proportion in the domestic deep-water cage culture industry.
  • Split I-frame and columnsThe I-frame (connector) and the column adopt a split structure.

Project Support

Overall communication from surface framework to anchorage packages

GENTAIN can combine the sea level, water depth, culture species, operation methods and project scale to communicate supporting solutions such as cage structure, net clothing and anchoring.

  • Confirm the frame specifications based on sea conditions, water depth and breeding scale
  • Confirm the net clothing and platform configuration based on the breeding species and operation methods
  • Communicate supply, installation and technical data support based on project rhythm
