In June 2024, Xinguangzheng delivered an 80x40x15m steel structure fruit export storage facility located in Accra, Ghana, designed specifically for fresh-keeping solutions for agricultural products. This facility adapts to Ghana’s equatorial climate and fruit trade demands, achieving an optimized cold chain design and efficient export maintenance system.
Customer Requirements
Our client is a Ghanaian fruit export alliance, primarily handling tropical fruits such as mangoes, pineapples, citrus, and bananas, headquartered in the Accra agricultural belt. With the booming growth of West African agricultural exports, the client’s storage needs have expanded dramatically: existing warehouses struggle to coordinate peak harvest seasons and diverse quality requirements. Meanwhile, Ghana’s natural conditions exacerbate challenges, including tropical hot and humid weather with an average annual humidity of 85%, risks of fruit spoilage, and regional earthquake and seasonal rain hazards. Traditional bamboo and wood warehouses have long construction cycles (13-19 months), with costs exceeding $160 per square meter, low fresh-keeping performance on fertile soil, and inability to meet strict standards of European and Asian markets.
Through multiple agricultural conferences and climate assessments, the Xinguangzheng team proposed a fresh-keeping building design solution:
- Tropical fruit anchoring: Covering at least 3200 square meters, supporting temperature-divided storage and sorting isolation areas.
- Swift harvest delivery: Project limited to within 5 months to synchronize with fruit season cycles.
- Ecological fresh-keeping protection: Structure moisture-proof and earthquake-resistant, incorporating ventilation measures to reduce spoilage rates by 45-55%.
- Trade streamlining: Configuration allows for later agricultural expansions, such as adding quality testing or solar cooling.
Solutions
Xinguangzheng focuses on fresh-keeping metal isolation and tropical integration for the fruit storage project. The facility adopts a reinforced steel structure system, with all components prefabricated in the factory, complying with ISO 9001 and Ghanaian regulations. This process enhances cold chain performance and on-site coordination, reducing rainy season interference.
Core Specifications Detailed:
- Dimensions and layout: 80 meters long, 40 meters wide, 15 meters high (eave height), total area 3200 square meters. Column-free open space, facilitating cooling zoning and conveyor line arrangements.
- Structural Components:
- Frame: Q355B agricultural-grade steel beams, load capacity 48 kN/m², adapting to light and heavy fruit loads.
- Roof and cladding: 0.9mm PUR insulation panels, R-value 5.4, resisting humid heat condensation fluctuations (24°C in winter to 36°C in summer).
- Foundation: Flexible flood-resistant pile foundation system, suitable for wetland deployment, facilitating drainage management and reuse.
- Custom Functions:
- Spacious loading area: Supporting 20-ton fruit trucks and automated sorting operations.
- Built-in ethylene exhaust ventilation and temperature zone controllers: Maintaining fruit freshness.
- 400 square meters management layer: For inspection monitoring and logistics integration. Material certificates are fully transparent, and our team (including local agricultural experts) used BIM to simulate rain floods and temperature changes, ensuring a 1.8 times safety margin.
Implementation Process
The facility was advanced in three phases, with a total duration of 4-5 months. We prefabricated components in specialized workshops in China, then shipped them by sea to the Ghana site for assembly.
- Prefabrication phase (1-2 months): Fine assembly in neutral humidity factories in China, reducing losses by 50% through strict inspection mechanisms. Each component underwent simulated hot and humid environment testing.
- Site preparation (16 days): For the tropics, flood-proof foundation solidification and pile foundation engineering. Immediate integration after containers docked, seamless Chinese export connection.
- Assembly and testing (2 months): Swift bolting installation, no welding interference. After deploying the ventilation system, rainy season simulated fresh-keeping.
For hot and humid condensation, we adopted anti-condensation protective layers. Additionally, it is recommended to reserve 15% of the agricultural project budget for cooling optimization to prevent later fruit repairs.
Results
After the facility went into production in June 2025, according to client feedback monitoring data, the steel structure building demonstrated the following advantages:
- Fresh-keeping efficiency: Zoned cooling system maintains constant temperatures of 0-10°C, significantly reducing post-harvest losses by 40%, initial reports show fruit freshness extended by 20-25%, supporting market supply.
- Structural endurance: During Ghana’s rainy season, the facility sustained zero damage from floods, thanks to earthquake-resistant pile foundations and insulation layers, ensuring long-term operational stability of over 50 years.
- Operational optimization: Large-span design improves sorting efficiency by 35%, data shows increased export turnover rates, supporting sustainable agricultural expansion.
- Ecological contribution: Rainwater recycling and energy-saving ventilation reduce water consumption by 30%, complying with Ghanaian environmental policies, and providing a green template for regional fruit trade.
