Product Description Product DescriptionHDPE Rectangular Enhanced fish farming cagesFor inshore, lakes and reservoirs, good for the square cages which single side length smaller than 15 meters. Include the single cage and combination cages.1.The cage material is marine special high-density polyethylene material which is environmental and 100% recyclable. It has the advantages of high strength, high toughness, anti-oxidation, acid and alkali resistance, impact resistance. 2. The structure is simple and strong, resistance coefficient is small, strong ability of anti-wind and waves, can withstand the 10 class of typhoon and the 6m waves. This structure can withstand the impact of external forces such as wind and waves to a certain extent, ensuring the stability of the fish cage in the marine environment. The frame's flexibility allows it to absorb wave energy, reducing structural stress. However, the specific stability is also related to factors such as the size of the fish cage, the installation method, and the environmental conditions of the sea area where it is located.3. Wide range of applications, can be set at -6m to -300m depth of the ocean, river, lake, reservoir etc. 4. The investment cost is relatively low, occupies a large proportion in the domestic dep-water cage culture industry. 5. The bracket(connector) and the column is separated.Detailed Photos   Product ParametersStock No.Length × width (M)Dia. of floating pipe (MM) Dia. of handrail pipe (MM) Dia. of stand pipe(MM)Breeding area(m2)Distance of the brackets(M)HSM0201020014×4200/25090110 Separated structure16≤2.0HSM0201020025×5200/25090110 Separated structure25≤2.0HSM0201020036×6250/31590/110110/125 Separated structure36≤2.0HSM0201020048×8250/315110125 Separated structure64≤2.0HSM02010200510×10315110125 Separated structure100≤2.0HSM02010200612×12315/350110/125125 Separated structure144≤2.0HSM02010200715×15315/350110/125125 Separated structure225≤2.0HSM02010200820×20350/400125125 Separated structure400≤2.0HSM02010200930×30350/400125125 Separated structure900≤2.0Company ProfileQingdao Haosail machinery Co., Ltd. is located in Qingdao, the central ocean city in northern China, and it is a national high-tech enterprise and technology innovation enterprise. Our company focuses on the R & D and production of the intelligent solution of deep-sea aquaculture equipment. Relying on advanced technology and reliable equipment, our company has long-term in-depth cooperation with customers in more than 20 countries such as United States, Australia, Singapore, Poland and Ukraine.Our company takes scientific and technological innovation as the driving force, inherits the enterprise culture of "Haosail, worthy of your trust", and builds the company into a brand enterprise with a sense of mission and competitiveness.Our AdvantagesHDPE, lightweight high-strength alloy materials and other new materials are adopted in the structure. Computer control, various anti-corrosive, anti fouling (attachments) and anti-aging technologies greatly improve the overall structural strength and flexibility of deep-sea aquaculture net cage, double the service life of the cage, highly reduce the daily maintenance and the cost of aquaculture in unit volume, and improve economic benefits.FAQ1. What is the main material of your square cages, and what are its advantages?Our square cages are primarily made of HDPE (High-Density Polyethylene), which offers:Corrosion resistance: Resistant to saltwater, chemicals, and microbial degradation.UV stability: Treated with anti-UV additives to prevent aging under long-term sunlight.High durability: Can withstand harsh marine environments and heavy loads.Environmental friendliness: 100% recyclable and non-toxic to aquatic life.2. What sizes and specifications of square cages are available? Can they be customized?Standard sizes range from 1m×1m to 10m×10m (depth can be customized from 2m to 8m).Customization options include:Cage dimensions (length, width, depth)Mesh size (0.5mm to 100mm, suitable for different fish/shellfish species)Frame structure (reinforced corners for high-wind areas)Additional features (escape-proof nets, feeding ports, monitoring mounts).3. Are these square cages suitable for both freshwater and saltwater aquaculture?Yes, HDPE square cages are designed for both freshwater (lakes, ponds) and saltwater (coastal areas, oceans). The material's anti-corrosive properties make it ideal for marine environments, while its lightweight structure is suitable for freshwater installations.4. How do you ensure the stability of the square cages in harsh weather?Stability is ensured through:HDPE floating frames: Buoyant and durable, with high load-bearing capacity.Anchor systems: Customizable anchors (concrete blocks, screw piles) based on water depth and current.Reinforced connections: All joints are heat-welded or bolted for anti-loosening.Wind/wave resistance design: Tested to withstand winds up to 100km/h and wave heights of 3m.5. What is the maintenance requirement for the square cages? How long is the service life?Maintenance: Minimal upkeep needed-regularly clean mesh to prevent algae buildup (recommended every 3-6 months). HDPE frames require no painting or rust protection.Service life: 8-10 years under normal use (depends on environmental factors; warranty typically covers 3-5 years).6. Can you provide a complete aquaculture system including square cages and accessories?Yes, we offer turnkey solutions including:Cage frames, nets, and floating systemsAccessories: mooring ropes, anchors, feeding systems, water quality monitorsInstallation guidance and on-site support (for large orders).
