Butterfly Roof Multi-Span Plastic Film Greenhouse for Commercial Vegetable & Flower Cultivation

Product Description

Product Description

Shouguang Zenong Greenhouse Engineering Co., Ltd supplies professional butterfly roof multi-span plastic film greenhouse solutions for commercial flower farms, vegetable bases and seedling nurseries.

Distinct from conventional gable or sawtooth greenhouses, it adopts special butterfly double-slope roof structure with bidirectional openable top vents on the ridge. The double-sided vent design forms smooth air convection inside the greenhouse, quickly discharging hot and humid air, effectively reducing disease probability for crops. The whole framework adopts  hot-dip galvanized square and round steel, connected by bolts without a large amount field welding, featuring stable structure and outstanding corrosion resistance. It is covered with high light transmittance, anti-aging, anti-drip PO or PE agricultural film.

Our engineers adjust bay size, vent opening range and structural load according to local rainfall, wind speed and temperature characteristics. Various auxiliary climate control and irrigation systems can be configured flexibly. This greenhouse is suitable for continuous large-area planting and standardized management. Each overseas project provides customized construction drawings, component lists and long-distance technical guidance.

Product Overview

Zenong butterfly roof multi-span plastic film greenhouse is a tailor-made commercial growing solution designed to solve high humidity and poor ventilation pain points in traditional film greenhouses.
Featuring a unique bidirectional butterfly top opening structure, this greenhouse achieves large-area overhead ventilation that far exceeds conventional side-vent-only designs. The symmetrical double-opening roof rapidly exhausts stagnant hot air and excessive moisture, maintaining a dry, fresh and well-ventilated internal environment throughout the planting cycle and effectively reducing fungal diseases and crop rot.
The whole greenhouse adopts standardized Q235 hot-dip galvanized steel structure with bolt assembly technology, ensuring high structural stability, wind resistance and zero field welding. Equipped with high-transmittance, anti-fog and anti-UV agricultural film, it guarantees uniform light distribution and stable microclimate.
We customize structural strength, vent opening angle and complete supporting systems according to local rainfall, wind speed and planting varieties. Highly adaptable for flower planting, seedling breeding and high-value vegetable cultivation in rainy, humid and subtropical regions. Zenong provides one-stop engineering design, full set accessories and professional remote installation service to help global growers achieve stable and high-yield commercial planting.
