1. Project Background
A commercial grower in South Africa was expanding production but faced severe climate-related challenges. Intense UV radiation, large temperature fluctuations, and seasonal winds caused rapid deterioration of their traditional film greenhouse. The structure required frequent repairs, struggled to maintain a stable environment, and could not support the grower’s goal of year-round production. To ensure durability and long-term performance, the customer decided to upgrade to a polycarbonate (PC) greenhouse known for its strong insulation, UV resistance, and structural reliability.
2. Key Challenges Faced by the Grower
Harsh Climate Conditions
The region experiences powerful sunlight and high UV exposure, leading to heat stress inside the greenhouse and quick aging of traditional covering materials. Sudden temperature drops at night further affected plant growth.
Vulnerability to Strong Winds
Seasonal winds caused film tearing, structural shaking, and temperature instability. The grower needed a greenhouse capable of withstanding these conditions without constant maintenance.
Inconsistent Growing Environment
Poor ventilation and weak insulation made it difficult to stabilize temperature and humidity, resulting in lower production efficiency and increased risk of pests and diseases.
High Cost of Frequent Replacements
Due to import logistics and installation labor, replacing old film greenhouses was costly. The customer needed a long-term investment that minimized future maintenance.
3. FANGCHENG’s Customized Solution
Durable PC Panel System with UV Protection
FANGCHENG selected 8–10 mm twin-wall polycarbonate panels, offering high light transmission while blocking harmful UV rays. This improved environmental stability and extended material lifespan.
Reinforced Steel Structure for Wind Resistance
A galvanized steel frame with strengthened connectors ensured the greenhouse could handle strong winds without deformation, significantly improving safety and durability.
Optimized Ventilation for Climate Control
Roof and side ventilation systems were designed to create natural, balanced airflow. This helped prevent heat buildup, maintained proper humidity, and ensured a healthier growing environment.
Enhanced Insulation for Temperature Stability
PC panels provided excellent thermal performance, reducing nighttime heat loss and helping crops maintain steady growth conditions throughout the day.
Improved Drainage and Water Management
High-capacity gutters and reinforced drainage channels prevented overflow during heavy rainfall and protected the structure from water-related damage.
4. Project Outcome
After installation, the PC greenhouse delivered notable improvements in productivity and environmental consistency. Internal temperatures became more stable, reducing crop stress and increasing uniformity. Light transmission improved, resulting in healthier plant growth and higher yields. The structure withstood strong winds without issue, giving the grower greater operational confidence. Maintenance needs decreased significantly, saving long-term costs. Overall, the greenhouse allowed the client to expand production capacity and improve market competitiveness.
