Ruize Steel manufactures the Sawtooth-type Multi-span Greenhouse with Skylight for agricultural projects that require more ventilation control than a basic sawtooth structure. The greenhouse combines a high-level sawtooth vent with an additional top opening, allowing warm and humid air to move upward and leave the growing area when the ventilation system is opened. The multi-span structure provides a continuous cultivation space, while the final frame, vent arrangement and covering material can be configured according to the installation location and crop requirements.
The design can combine passive natural ventilation with mechanical cooling or other environmental control equipment. This makes it suitable for projects where ventilation, humidity management and seasonal climate adjustment need to be considered together.
The high-level sawtooth opening is combined with an additional top vent to improve air exchange and provide more ventilation control.
The skylight can work together with side ventilation, shading, fans or cooling equipment according to seasonal conditions.
The frame uses hot-dip galvanized steel components for corrosion protection in outdoor agricultural environments.
Connected spans create a continuous protected cultivation area and allow different planting or management zones to be arranged within one project.
PO or EVA agricultural film can be selected according to light, climate and crop requirements.
Warm air naturally rises inside a greenhouse. The elevated sawtooth opening provides a high-level path for heat and humidity to escape, while side ventilation can bring outside air into the structure. Opening the top skylight provides an additional route for air movement when stronger ventilation is required.
Actual ventilation performance depends on factors such as roof opening size, side ventilation, outside wind conditions, greenhouse dimensions and operating strategy. These factors should be considered during project design rather than relying on one fixed ventilation specification.
The Sawtooth-type Multi-span Greenhouse with Skylight can be configured for protected cultivation applications including:
● Leafy vegetables and common fruit vegetables
● Vegetable and fruit seedling production
● Flowers and potted plants
● Small fruit cultivation and seasonal picking projects
● Other crops requiring controlled ventilation and protected growing conditions
The configuration is particularly suitable for warm and humid growing regions, while the skylight, shading and heating systems can be selected according to seasonal climate requirements.
| System | Main Function |
|---|---|
| Electric Roof Skylight | Provides adjustable high-level ventilation |
| Side Roll-Up Ventilation | Supports natural air exchange through the lower sides |
| External Shading | Reduces excessive solar radiation during hot periods |
| Circulation Fans | Improves internal air movement when additional airflow is required |
| Fan and Pad Cooling | Provides active cooling for suitable high-temperature projects |
| Irrigation and Fertigation | Supports controlled water and nutrient delivery |
| Seedling Benches | Supports organized nursery and seedling production |
| Environmental Monitoring | Monitors temperature, humidity and other selected growing conditions |
Greenhouse dimensions and structural specifications should be determined according to the installation site, crop requirements and local environmental conditions. Key configuration factors include:
● Overall greenhouse width and length
● Span and bay spacing
● Eave and ridge height
● Skylight opening arrangement
● Side ventilation configuration
● PO or EVA film covering
● Local wind and snow conditions
● Rainfall and drainage requirements
● Shading and cooling requirements
● Irrigation and fertigation requirements
| Configuration | Main Characteristic | Typical Consideration |
|---|---|---|
| Single-sided Sawtooth Multi-span Greenhouse | Basic high-level sawtooth ventilation | Suitable for projects with straightforward natural ventilation requirements |
| Sawtooth-type Multi-span Greenhouse with Skylight | Sawtooth ventilation plus additional top opening | Suitable when more adjustable ventilation and seasonal climate control are required |
| Double-sided Sawtooth Multi-span Greenhouse | Ventilation openings arranged on both sides of the roof structure | Suitable for projects requiring a different high-ventilation structural layout |
The appropriate configuration depends on the site climate, greenhouse size, crop type, ventilation target and equipment requirements.
PO and EVA films can be selected for the roof and side covering according to the required greenhouse application. The roof and gutter arrangement should also be designed around local rainfall and drainage requirements to guide rainwater toward the designated drainage system.
The greenhouse uses modular structural components for on-site assembly. Routine maintenance focuses on the frame, film fixing points, skylight mechanism and auxiliary systems.
● Inspect structural connections and galvanized components.
● Check film fixing systems and replace damaged covering when required.
● Inspect the skylight opening mechanism and moving parts.
● Maintain side ventilation and shading systems.
● Check irrigation, cooling and monitoring equipment regularly.
● Combined sawtooth and skylight ventilation configuration
● Flexible natural and mechanical ventilation options
● Hot-dip galvanized steel frame
● PO and EVA film covering choices
● Compatible with shading, cooling, irrigation and monitoring systems
● Project-based design for different climates, crops and site conditions
It is a multi-span greenhouse that combines a sawtooth roof ventilation structure with an additional top skylight. The two openings provide greater flexibility for managing heat and air exchange.
The main difference is the additional skylight, which provides another high-level ventilation opening and allows the ventilation strategy to be adjusted according to weather and crop conditions.
Yes. An electric opening mechanism can be configured where required, with the exact drive and control arrangement determined by the greenhouse design.
Yes. The high-level ventilation design is particularly useful for projects where heat and humidity removal are important. Additional fans, shading or cooling systems can be added according to the local climate.
Yes. For colder regions, the greenhouse can be combined with insulation, heating and suitable ventilation control systems according to the crop and local winter conditions.
PO and EVA agricultural films can be selected according to the required light, climate and crop conditions.
Yes. The dimensions, span, height, skylight arrangement, ventilation, covering material, shading and auxiliary systems can be configured according to the project.
Please provide the greenhouse size, installation location, crop type, preferred covering material, ventilation requirements, local wind and snow conditions where applicable, and any shading, cooling or irrigation systems required.
Send Ruize Steel your greenhouse dimensions, installation location, crop type and required climate-control systems to receive a suitable Sawtooth-type Multi-span Greenhouse with Skylight configuration.
