Sawtooth Multi-Span Plastic Film Greenhouse for Tropical & Subtropical Crop Cultivation

Product Description

Product Description

Shouguang Zenong Greenhouse Engineering Co., Ltd provides professional sawtooth multi-span plastic film greenhouse solutions, specially optimized for high-temperature and high-humidity tropical and subtropical regions.

Different from conventional gable multi-span greenhouses, it adopts characteristic sawtooth roof structure with continuous top vents on the ridge. Hot air inside the greenhouse rises and discharges naturally through the top openings, achieving efficient passive ventilation and cooling, greatly reducing reliance on mechanical cooling equipment. The whole framework adopts hot-dip galvanized square and round steel, connected by bolts without a large amount of on-site welding, stable and anti-corrosion. It is covered with anti-UV agricultural PO or PE film to ensure high light transmittance while resisting aging.

We adjust the bay size, vent height and structural load according to local temperature, rainfall and wind speed. A full set of auxiliary equipment can be equipped to control temperature, humidity and pests. This greenhouse is widely used for large-scale commercial farms and seedling bases in hot areas. Each order comes with customized construction drawings, component lists and long-distance technical guidance for overseas customers.

Product Overview 

Developed specifically for large-scale commercial planting in tropical and subtropical high-temperature, high-humidity regions, the Zenong sawtooth multi-span film greenhouse adopts innovative serrated roof ventilation architecture that differentiates it from traditional multi-span greenhouses.
The entire load-bearing structure adopts full hot-dip galvanized  steel with standardized bolt assembly, ensuring overall structural stability, strong wind resistance and long-term anti-corrosion performance. The continuous top sawtooth ventilation openings form an efficient upper and lower air convection system with side vents, relying on natural hot air rising principle to realize passive cooling and dehumidification, effectively reducing mechanical energy consumption throughout the year.

Matched with high-transmittance, anti-aging and anti-drip agricultural film, the greenhouse maintains uniform indoor lighting and stable growing environment. Our team optimizes vent height, structural load and overall layout according to local typhoon, heavy rainfall and high-temperature climate characteristics. It supports flexible integration of shading, cooling, irrigation and intelligent control systems, perfectly adapting to large-scale seedling breeding, tropical vegetable and economic crop commercial cultivation. We provide one-stop customized design, complete supporting accessories and professional remote installation guidance for global agricultural investors.
