CFGET Greenhouse Structure
Greenhouse structures evolved from arch and peaked roofs to meet crop and climate needs, improving efficiency and control.
🌱 Sawtooth Greenhouse
The Sawtooth Greenhouse gets its name from its distinctive sawtooth-shaped roof structure, designed primarily for hot, humid, or tropical climates. The open roof vents allow for enhanced natural ventilation, improving air circulation and preventing excessive heat buildup inside the greenhouse. This passive cooling design significantly reduces the need for mechanical cooling, making it an energy-efficient solution.
Typically built with galvanized steel frames, sawtooth greenhouses can be covered with PE/PO plastic film, polycarbonate panels (PC), or glass, making them ideal for tropical, subtropical, and warm climate regions. They are widely used in vegetable and fruit cultivation, flower production, and high-efficiency agricultural projects. Their effective airflow system makes them particularly suitable for crops requiring high ventilation, such as tomatoes, peppers, melons, orchids, and leafy greens.
Structural Advantages
✅ Superior Natural Ventilation
✅ Reduced Cooling Energy Consumption
✅ Ideal for Hot and Humid Climates
✅ Optimized for High-Ventilation Crops
💡CFGET
The Sawtooth Greenhouse is an evolved structure of multi-span greenhouses, designed specifically for regions with fixed single-sided airflow, such as coastal areas in China, Malaysia, and Southeast Asia.
Its one-way ventilation system provides excellent airflow, while the elevated roof structure expands the internal space, allowing heat to dissipate more efficiently. When combined with internal circulation fans, this design further enhances air movement and overall ventilation efficiency. However, it is crucial to carefully assess the local wind direction during construction to optimize its ventilation performance. Additionally, the sawtooth roof design improves rainwater drainage, preventing water accumulation and enhancing the greenhouse’s durability.

✅ 10 Simple FAQ for Sawtooth Greenhouse
A sawtooth greenhouse uses a roof shape that looks like teeth of a saw. This design brings in more light and helps plants grow better.
The sawtooth design gives even light, good ventilation, and better climate control. It works well for large-scale commercial greenhouses.
It is great for vegetables, fruits, flowers and medicinal plants. Because the light and climate are well-managed, crops perform well.
The “tooth” roof canopy brings in overhead daylight and supports ridge vents. This helps cool air flow and good light for plants.
We use strong galvanized steel for the frame, and you can choose glass, PC sheet or film for the cover. Your choice depends on budget and climate.
Yes. We design based on your local climate—wind, snow, rain or heat. The sawtooth structure is adaptable to tough weather.
Time depends on size and system. Typically a few weeks to a few months from production to installation when all is planned well.
• Your land size and shape
• Local weather data (wind, snow, sun)
• Crops you want to grow
• Budget and desired systems (irrigation, ventilation)
This helps us design your ideal sawtooth greenhouse.
Costs depend on size, materials, systems and crops. Return depends on crop value and efficiency. With the right setup your investment can pay back in a few years.
The steel frame lasts many years. Glass or PC sheet covers last 10 + years. Film covers may need replacing every 3-5 years. Regular checking of structure, cover and systems keeps your greenhouse running well.
