The multi-span greenhouse is an arch-shaped structure designed for large-scale agricultural operations. By connecting multiple spans, it provides a stable climate environment across thousands of square meters. These intelligent greenhouses are equipped with advanced automation, including external sunshade systems, internal thermal insulation, and wet curtain fan forced ventilation.
Applications: Perfect for growing tomatoes, cucumbers, peppers, eggplants, and strawberries hydroponically. The UV-resistant plastic film ensures optimal light transmission and crop protection.

1. Main Body Structure
Skeleton adopts double-sided hot-dip galvanized steel. Roof form is double arc arch type. Wind resistance is reinforced through high-quality low-carbon steel components.
2. Covering Materials
Top and surrounding walls are covered with PEP Lide film (0.15mm thickness) providing excellent durability and climate control for year-round farming.
3. Ventilation System
Equipped with manual or electric film rolling windows at the top and sides. Includes 25-mesh insect nets to protect crops while allowing airflow.
4. External Sunshade
Driven by steel wire with a smooth motor operation. The black tiled net provides a 70% shading rate, effectively controlling temperature and light intensity.
5. Cooling System
Combines paper porous wet curtains with water circulation and powerful fans. Evaporative cooling significantly reduces indoor temperatures during hot seasons.
6. Internal Sunshade
Adjusts shading rates and assists in heat preservation. It also helps in water and moisture retention, creating a stable micro-climate for sensitive plants.

Frequently Asked Questions
What are the main benefits of a multi-span plastic film greenhouse?
It offers a large coverage area with a stable internal temperature, high automation for ventilation and shading, and is highly cost-effective for large-scale vegetable and seedling cultivation.
Which crops are best suited for this hydroponic system?
The system is ideal for tomatoes, cucumbers, peppers, eggplants, strawberries, and various leafy greens like lettuce.
How does the cooling system work in hot weather?
It uses a wet curtain-fan system. Water evaporates from the porous curtain as air is drawn through by fans, converting sensible heat into latent heat and significantly lowering the greenhouse temperature.
What type of steel is used for the greenhouse skeleton?
The structure uses double-sided hot-dip galvanized steel pipes, ensuring strong wind resistance and long-term protection against corrosion.
Is the greenhouse film UV resistant?
Yes, the high-quality PO/PE plastic film used is UV resistant and provides over 90% light transmittance for optimal plant growth.
Can the greenhouse be customized?
Absolutely. Spans, eaves heights, film thickness, and integrated systems (irrigation, ventilation, shading) can all be customized to meet specific agricultural needs.
