ABC Machinery successfully delivered 15,900 enriched chicken cages to a poultry farm in French Polynesia.
For the island’s high-humidity and high-salinity environment, as well as old poultry house renovation requirements, we provided a corrosion-resistant and customized integrated solution based on enriched colony cages.
Existing Poultry House Condition
Our technical team conducted a detailed on-site evaluation of the project and confirmed that the original poultry house structure is in good condition and can still be used.
For the aging internal equipment and low level of automation, we developed an upgrade plan. While retaining the existing building structure, we introduced modern poultry farming equipment to improve operational efficiency and production performance.
Challenges of Upgrading an Existing Poultry House
Compared with building new poultry houses, renovating existing ones requires more practical considerations.
First, the dimensions of the existing poultry house are fixed, so standard equipment cannot be directly applied. Instead, customized designs are required based on the actual site size to ensure a reasonable layout while maintaining space utilization and daily management efficiency.
Second, the project is located in Tahiti, French Polynesia, a typical island climate with high humidity throughout the year. Surrounded by the ocean, the air contains a high level of salt, which places higher requirements on the corrosion resistance of poultry cages and related equipment.
To meet these conditions, ABC Machinery uses a hot-dip galvanized process to manufacture the enriched colony cages system, improving its anti-rust and anti-corrosion performance and ensuring stable long-term operation in high-humidity and high-salt environments.
In addition, due to the long transportation cycle in island regions, any equipment failure or replacement of parts can lead to higher time and cost. Therefore, customers place great importance on equipment quality and service life, which is also a key focus in ABC Machinery’s solution design.
Customized Enriched Colony Cage Solution
After understanding the client’s requirements and the site conditions, we developed a professional upgrade design plan.
First, based on the existing poultry house structure, we maximize the stocking capacity while keeping the original building intact.
Second, we design customized layouts for each poultry house according to their different dimensions, instead of using a uniform standard design.
Third, we improve the level of automation in the farming system to reduce labor input and increase management efficiency.
Fourth, according to the high-humidity and high-salinity island environment of French Polynesia, we optimized the equipment materials and structure to ensure long-term stable operation.
This phase-one upgrade project includes four layer poultry houses (P1, P2, P3, and P4). ABC Machinery will complete the equipment replacement and system upgrade step by step according to the construction schedule.
The overall project plan is as follows:
| Building | Length × Width | Units × Rows × Tiers × Birds/Cage | Places |
|---|---|---|---|
| P1 | 60 × 12 m | 40 × 4 × 4 × 25 | 16,000 |
| P2 | 60 × 8.69 m (alley 98 cm critical) | 40 × 3 × 4 × 25 | 12,000 |
| P3 | 75.6 × 9 m | 53 × 3 × 4 × 25 | 15,900 |
| P4 | 75.34 × 9.5 m | 53 × 3 × 4 × 25 | 15,900 |
| Total | – | – | 59,800 |
The P4 poultry house is designed for a stocking capacity of 15,900 laying hens. It is the first implementation in the phase-one upgrade project and also the first delivery project between ABC Machinery and the client.
With the successful implementation of the P4 poultry house, the P1, P2, and P3 poultry houses will be upgraded one by one according to the project plan.
Once the entire phase-one project is completed, the total stocking capacity will reach 59,800 laying hens, forming a modern and automated layer poultry farming base.
Design for High-Humidity Coastal Climates
The client’s project site is located in a typical island region, with high humidity throughout the year. Surrounded by the ocean, the air contains a high level of salt, which makes corrosion resistance and reliability essential for the customized equipment.
We use hot-dip galvanized steel to manufacture the enriched colony cages, improving their resistance to salt spray and extending service life.
At the same time, we optimized the connection structure and key load-bearing components of the equipment.
In the overall structural design, a modular assembly system is adopted. The cage frame, vertical supports, and horizontal reinforcement parts are combined through standardized connection nodes. This design avoids structural failure caused by weld corrosion in traditional welded structures under high-salt conditions.
For the connection method, high-strength galvanized bolts with anti-loosening designs are used. This ensures that all components remain firmly connected and reduces the risk of loosening over time, while also making future disassembly and maintenance easier. At key load-bearing points, double reinforcement structures are added to improve stability under strong wind and long-term operation conditions.
For corrosion-prone areas such as contact surfaces and joint gaps, additional anti-corrosion treatments are applied. We also optimized drainage and ventilation paths to prevent long-term accumulation of rainwater and salt mist, thereby reducing the risk of corrosion from the source.
Conclusion
The P4 poultry house has been successfully signed and implemented as the first order of Phase One by ABC Machinery.
It is also the first project within Phase One, while P1, P2, and P3 poultry houses will be carried out subsequently under the same phase according to the project plan.
This project also provides an important reference for the standardized design and unified construction of the Phase One poultry houses using enriched colony cages systems.
Once all four poultry houses in Phase One are completed, the total capacity of the farm will reach approximately 59,800 laying hens. After completion, the project will achieve larger-scale production, more stable operation, and more consistent profitability.
