Sawtooth Greenhouse

The Sawtooth Greenhouse is a specialized multi-span agricultural greenhouse featured with unique sawtooth-shaped roof design, professionally developed for high-temperature and high-humidity tropical and subtropical regions. Different from conventional arched greenhouses, its staggered vertical roof vents and flat-tooth structure provide superior natural ventilation and rapid heat dissipation performance. Widely used for leafy vegetables, flowers, seedlings and tropical crop cultivation, it has become the most preferred greenhouse type for summer anti-high-temperature planting and year-round production in low-latitude hot climate areas.

The most prominent advantage of the Sawtooth Greenhouse is its excellent natural ventilation system. The vertical top vents are arranged in a regular sawtooth distribution, forming an automatic hot air exhaust channel. Hot air accumulates at the top of the greenhouse and can be quickly discharged directly through the vertical vents, while cool outside air continuously enters from the side openings. This forms an efficient upper-exhaust and lower-intake air circulation system, which realizes rapid air exchange without relying on a large number of exhaust fans. It effectively reduces indoor high temperature stuffiness in hot summer and greatly lowers mechanical cooling energy consumption.

The overall frame adopts high-strength hot-dip galvanized steel structure with integrated industrial welding and anti-corrosion treatment. The whole skeleton features stable mechanical performance, strong wind pressure resistance and long service life up to 15–20 years under long-term outdoor exposure. All connecting fittings, bolts and film locking systems are made of matched anti-rust accessories to ensure firm structure, no deformation and no air leakage. The optimized tooth-shaped roof structure disperses wind force evenly, ensuring structural stability even under strong monsoon and storm weather, adapting well to complex coastal and high-temperature climatic environments.

This greenhouse adopts high-transmittance UV-stabilized polyethylene film as the standard covering material. The high-quality agricultural film maintains high light transmittance while resisting ultraviolet aging and rainwater erosion, ensuring sufficient uniform natural light for crop photosynthesis throughout the growing season. The special sawtooth roof design reduces light blocking and makes indoor light distribution more uniform compared with traditional greenhouses. For areas with intense sunlight, an external sunshade system can be installed to soften strong light and prevent crop sunburn, creating a mild and suitable light environment.

The large and continuous internal space of the sawtooth multi-span structure supports large-scale standardized planting and mechanized operation. It is suitable for dense planting of leafy vegetables, potted flowers, seedling breeding and high-value cash crops. The efficient natural ventilation always keeps indoor air fresh and humidity balanced, effectively inhibiting high-temperature and high-humidity induced fungal diseases and pests, reducing pesticide usage and improving crop quality. Meanwhile, it can be equipped with drip irrigation, spray cooling, insect-proof nets and intelligent environment monitoring systems to realize refined and automated planting management.

With outstanding heat dissipation capability, stable structure, high light efficiency and low operation cost, the Sawtooth Greenhouse solves the pain points of difficult heat dissipation and low summer output in traditional greenhouses. It is highly adaptable to tropical, subtropical and coastal high-temperature regions. As a professional energy-saving and high-yield agricultural facility, it provides reliable planting solutions for modern large-scale commercial farms, flower bases and seedling cultivation projects worldwide.
