Product Description
The Sainpoly Sawtooth greenhouse adopts hot-dip galvanized light steel structure combined with high-strength anti-aging agricultural film, with an asymmetric streamline contour in appearance. The overall force is simple and clear, and it has excellent resistance to snow pressure and wind resistance. The enclosure system can be equipped with single-layer film, double-layer film or pure insect proof net composite structure according to planting needs. The application of new technology for thin films extends their service life by 2 to 4 years compared to ordinary films. The greenhouse is compatible with various scenarios such as vegetables, fruits, seedlings, and hydroponics, and can be flexibly equipped with heating or cooling systems. Sainpoly provides one-stop services from design, installation to delivery and after-sales, balancing cost control and operational convenience.

Product Advantages
1
The main skeleton of the Sawtooth greenhouse is made of Q235B and above grade steel, which has been hot-dip galvanized for corrosion resistance. The zinc layer adhesion is significantly higher than that of conventional profiles, and the cross-sectional bearing capacity is sufficient to withstand large coverage loads. The structural design service life exceeds 15 years.
2
The Sawtooth greenhouse cover film supports both double-layer and single-layer structural options, and the measured transmittance can reach over 90%. When using a double-layer configuration, the thermal resistance of the enclosure structure significantly increases, and the insulation performance is improved by 30% compared to a single-layer configuration, making it suitable for large-scale production under different climatic conditions.
3
The Sawtooth greenhouse can be equipped with various built-in systems such as electric film rolling system, wet curtain fan cooling system, external shading net, internal insulation system, and IoT intelligent control cabinet, and supports remote control on mobile phones or PCs.
4
90% self-produced rate, CE certification, 15 patents, strict three inspection system, zero defects at the factory.Precision production of high-end equipment.
5
We provide customized services for climate data collection, structural strength verification, foundation design, environmental control selection, irrigation schemes, and supplementary lighting systems at the project site. We also provide installation drawings and engineer installation guidance.

Application and Solutions
Extremely cold in winter，conventional greenhouse vegetable crops will experience irreversible freezing damage.
Avoid freezing
Snowproof Roof
High Light Transmittance
High energy cost
Long life design
Avoid freezing
When the ambient temperature drops to -25 ℃ in a regular greenhouse, vegetables are at risk of frostbite and even death. The Sawtooth greenhouse adopts a double-layer inflatable film structure, forming a static air insulation layer between the two layers of film, which improves the insulation efficiency by more than 30% compared to a single layer. Combined with the internal insulation system and reserved heating interfaces, the temperature inside the greenhouse can be effectively maintained above the crop tolerance threshold, completely eliminating the phenomenon of low-temperature freezing damage.

FAQ
1
Q:What is the difference between a Sawtooth greenhouse and a traditional arched greenhouse?
A:The most distinctive feature of the Sawtooth greenhouse is its asymmetric sawtooth-shaped roof, with vertical or inclined vents installed at the high points. These vents utilize natural wind force to create negative pressure, extracting hot air from inside the greenhouse. As a result, its ventilation and cooling effect is significantly better than that of traditional arch-shaped greenhouses. In addition, the sawtooth structure maintains good structural stability even under large-span conditions, making it particularly suitable for hot regions or summer cultivation.
2
Q: What is the service life of the film? Is it convenient to replace?
A:The greenhouse film is imported anti-aging and anti dropping film, with a service life of 3-5 years. The film adopts a card slot fixed design, which makes the replacement operation simple and convenient, and the subsequent maintenance cost is relatively low. The main steel frame structure has undergone full hot-dip galvanizing treatment, with a galvanized layer thickness of ≥ 65 µ m and a service life of over 15 years. The main structure is guaranteed for 10 years.
3
Q: What intelligent environmental control devices can be matched?
A:The Sawtooth greenhouse supports multiple intelligent environmental control systems, including:
Electric film rolling system (automatic control of ventilation opening and closing)
Wet curtain fan cooling system
External shading net and internal insulation system
IoT intelligent control cabinet (supporting remote control via mobile phone/PC)
Flexible selection can be made according to planting needs.

Q: Do you provide installation services? Is remote guidance feasible?
A: We provide two modes: ① Send technicians from the headquarters for on-site guidance; ② Provide detailed installation videos and manuals, with full remote assistance, and installation can be completed smoothly even for beginners.
5
Q: Can Sawtooth greenhouses be customized in size? What crops are suitable for?
A:Support full-size and full system customization, flexible design according to customer land parcels and planting needs. Widely applicable to various scenarios such as vegetable cultivation (tomatoes, colored peppers, cucumbers, etc.), fruit cultivation, seedling cultivation, hydroponics, etc.
6
Q: Are your Sawtooth greenhouse materials compliant with EU standards?
A: Yes. We have CE certification, and steel, polycarbonate sheets, sealants, etc. all comply with relevant EU standards, and can assist customers to pass local acceptance.
