Single-Sided Sawtooth-Type Multi-Span Greenhouse

Ruize Steel factory manufactures the Single-sided Sawtooth-type Multi-span Greenhouse for agricultural projects that require improved natural ventilation within a connected greenhouse structure. The single-sided sawtooth roof creates a high-level ventilation opening where warm and humid air can escape, while lower-side ventilation can introduce outside air and improve internal air movement. Multiple bays can be connected to form a continuous growing area, with the final structure configured according to local climate, crop requirements and site conditions.

The greenhouse combines a relatively straightforward steel frame with flexible film covering and can be equipped with side roll-up ventilation, shading, insect netting, cooling, irrigation and fertigation systems. This makes the structure suitable for projects where natural ventilation and adaptable greenhouse management are important.

Key Features

High-Level Sawtooth Ventilation

The raised roof opening helps release accumulated heat and humidity and supports natural air exchange.

Suitable for Hot and Humid Areas

The ventilation structure is well suited to projects where heat and humidity management are important during crop production.

Simple and Practical Structure

The single-sided sawtooth layout provides a straightforward greenhouse structure with flexible equipment options.

Multi-Span Growing Area

Several bays can be connected to create larger cultivation areas and separate crop management zones.

Galvanized Steel Frame

Hot-dip galvanized steel components provide corrosion protection for outdoor agricultural applications.

Flexible Film Covering

PE, EVA or PO agricultural film can be selected according to the project, crop and local growing conditions.

Natural Ventilation Design

The sawtooth roof places the ventilation opening at a higher position than the main growing area. As warm air rises, the high-level opening provides a route for heat and moisture to leave the greenhouse. When combined with side ventilation, the resulting air exchange can improve airflow through the growing space.

Actual ventilation performance depends on roof vent size, side opening arrangement, wind direction, outside temperature and other site conditions. The ventilation configuration should therefore be designed according to the local climate and greenhouse layout.

Suitable Crops

The Single-sided Sawtooth-type Multi-span Greenhouse is suitable for protected cultivation of:

● Leafy vegetables

● Vegetable seedlings

● Fruit and vegetable seedlings

● Common flowers and potted plants

● Other crops requiring protected growing conditions

Optional Greenhouse Systems

Structural and Project Configuration

The greenhouse structure should be configured according to the installation site rather than using one fixed specification for every project. Important design factors include:

• Greenhouse length and total width
• Span and bay spacing
• Eave and ridge height
• Roof vent arrangement and opening size
• Local wind and snow conditions
• Rainfall and drainage requirements
• Film covering type
• Ventilation and shading requirements
• Crop type and growing method
• Irrigation and cooling requirements

Multi-Span Layout for Crop Management

The connected multi-span structure allows the greenhouse area to be divided into different cultivation zones. Separate bays can be arranged for different crops, planting schedules or irrigation requirements.

• Different crop varieties can be managed in separate zones.
• Seedling and production areas can be arranged within the same greenhouse project.
• Different irrigation or fertigation zones can be planned according to crop requirements.
• Additional spans can be incorporated according to available land and project planning.

Covering and Frame Options

The greenhouse can use PE, EVA or PO agricultural film according to the required light transmission, climate conditions and crop application. The frame is based on hot-dip galvanized steel components, while the final member dimensions and spacing should be selected according to the structural design and site conditions.

Installation and Maintenance

The modular greenhouse structure is designed for on-site assembly. Routine maintenance mainly involves checking structural connections, film fixing points, ventilation mechanisms and auxiliary equipment.

• Inspect frame connections and structural components regularly.
• Check film and fixing systems for damage or loosening.
• Maintain roll-up ventilation and other moving components.
• Inspect irrigation, cooling and shading equipment.
• Replace damaged covering or accessories when necessary.

FAQ

What is a Single-sided Sawtooth-type Multi-span Greenhouse?

It is a multi-span greenhouse with a single-sided sawtooth roof ventilation arrangement. The elevated vent helps release warm and humid air and improve natural ventilation within the growing area.

What climates are suitable for this greenhouse?

It is particularly suitable for hot and humid regions where natural air exchange is important. The final ventilation and structural configuration should be adapted to the local climate.

Can natural ventilation alone cool the greenhouse?

Natural ventilation can improve heat and humidity removal, but its effectiveness depends on outdoor conditions and the greenhouse ventilation design. Fans, shading or cooling systems can be added when additional climate control is required.

What film can be used for the greenhouse?

PE, EVA and PO agricultural films can be selected according to the crop, climate and required greenhouse performance.

Can multiple greenhouse spans be connected?

Yes. Multiple spans can be connected to create a larger cultivation area. The final layout depends on the available land, structural design and project requirements.

Can ventilation and cooling systems be added?

Yes. Side roll-up ventilation, insect netting, shading, circulation fans, fan-and-pad cooling and irrigation systems can be configured according to the project.

Is this greenhouse suitable for vegetable seedlings?

Yes. It can be configured for common vegetable and fruit seedlings, with suitable ventilation, shading, irrigation and nursery equipment according to the crop requirements.

Can the greenhouse be customized?

Yes. The span, length, height, ventilation arrangement, covering material and auxiliary systems can be configured according to the project.

What information is needed for a quotation?

Please provide the greenhouse size, installation location, crop type, preferred covering material, ventilation requirements and any shading, cooling or irrigation systems required.
