Core Structure

Sawtooth Roof (Most Crucial) The roof consists of alternating high and low spans, forming a row of "saw teeth."

Electric/manual ventilation windows are installed at the highest point of each tooth, utilizing the principle of rising hot air to create a chimney effect, resulting in extremely strong natural ventilation.

The ventilation openings can be vertical or angled, allowing ventilation even in rainy weather without getting wet.

Hot-dip Galvanized Steel Structure Frame Columns, beams, gutters, and trusses are all made of hot-dip galvanized steel pipes/sections, providing corrosion resistance, stability, and resistance to wind and snow.

Mostly multi-span structures, allowing for unlimited splicing, offering ample internal space, no obstructed pillars, and convenient mechanized operation.

Covering Materials:

Commonly used: PO anti-drip film, PC polycarbonate sheet, tempered glass.

Light transmittance can reach 90%+, providing uniform diffused light and promoting uniform crop growth.

Supporting Systems (Standard/Optional):

Roof window ventilation system (core);

Side roll-up film ventilation, insect netting;

External/internal shading;

Evaporative cooling with fans;

Integrated water and fertilizer system, misting/spraying;

Intelligent temperature control (temperature, humidity, and light intensity linkage).

Reference Technical Parameters

Applicable Scenarios

Summer vegetable cultivation in southern regions (leafy vegetables, melons, beans)

Flower cultivation (roses, carnations, potted flowers)

Factory seedling production (vegetable seedlings, melon seedlings, medicinal herb seedlings)

High-value-added crops (strawberries, edible fungi, Chinese medicinal herbs)

Tropical/Subtropical crops (dragon fruit, passion fruit, bananas, etc.)

Large-scale bases requiring year-round production, rain-sheltered cultivation, cooling, and disease prevention
