The sawtooth film greenhouse was developed to address the dual needs of effective ventilation and regional climate adaptability in traditional greenhouse designs.

Early multi-span film greenhouses primarily relied on top or side roll-up ventilation. In hot and humid regions, this often led to insufficient ventilation efficiency, causing excessively high indoor humidity and subsequent crop diseases. Furthermore, relying on mechanical ventilation in such enclosed environments significantly increased energy costs.

To solve this pain point, agricultural facility engineers adapted the ventilation design principles of industrial sawtooth roofs. By redesigning the side walls into openable sawtooth-shaped slopes, this structure utilizes the stack effect (thermal buoyancy) to rapidly exhaust hot, humid air, while retaining the inherent advantages of film greenhouses: low cost and high light transmittance.

Through continuous technological iterations, the sawtooth film greenhouse has been progressively equipped with supporting systems such as shading and thermal insulation. It has now become a specialized agricultural facility perfectly suited for hot and humid climates.

The multi-span film greenhouse is a preferred facility for large-scale modern agricultural cultivation. Featuring a lightweight steel framework and covered with high-strength, long-life anti-drip plastic film, it perfectly balances economic viability with practical utility.

Adopting a multi-span connected design, this greenhouse breaks through the spatial limitations of single-span structures, increasing land utilization to over 85%. This spacious layout facilitates the entry and operation of large-scale agricultural machinery and intelligent equipment. The plastic film offers excellent light transmittance and thermal insulation, allowing for precise regulation of temperature, humidity, and lighting conditions inside the greenhouse. It is highly adaptable to various planting scenarios, including vegetables, flowers, and seedling raising.

Additionally, its supporting systemsâ??such as roll-up ventilation, external shading, and drip irrigationâ??enable refined environmental management and significantly reduce labor costs. Compared to glass greenhouses, multi-span film greenhouses offer lower construction costs and shorter installation cycles, making them the ideal choice for small and medium-sized planting bases and agricultural parks aiming to reduce costs and increase efficiency.

The Venlo-type aluminum-gutter glass greenhouse is a classic facility agriculture equipment originating from the Netherlands. Renowned for its compact structure, superior light transmission, and highly efficient operation and maintenance, it has become the mainstream greenhouse type worldwide.

The greenhouse is covered with high-transmission float glass, achieving a light transmittance of over 90%. Paired with an anti-UV coating, it not only ensures high photosynthetic efficiency but also effectively blocks harmful radiation. The framework is constructed from hot-dip galvanized steel, offering excellent corrosion resistance and a service life of over 15 years. With strong wind and snow load capacities, it is highly adaptable to diverse climatic environments across different regions.

A core advantage of this greenhouse is its intelligent control system, which can integrate modules for temperature and humidity control, fertigation, shading, and ventilation. Through real-time environmental data monitoring via sensors, the system precisely regulates temperature, humidity, light, and COâ?? concentrations, enabling uninterrupted year-round cultivation. Whether for vegetable seedling raising, flower cultivation, or the planting of high-value cash crops, it significantly boosts both yield and quality while reducing labor costs.

Compared to traditional greenhouses, it increases space utilization by 20% and reduces energy consumption by 15%. Combining ecological sustainability with economic benefits, it is the ideal choice for large-scale and intensive modern agricultural production.

The aluminum gutter greenhouse offers a variety of combination cover options, including full glazing, glass roof + polycarbonate honeycomb walls, full polycarbonate cover, sandwich panels and other customized combinations to suit your needs.
