2.Main Structural Composition

2.1 Galvanized Steel Frame

Raw material:Heavy-duty hot-dip galvanized round steel pipe,passivation anti-corrosion treatment,service life over 15 years,resistant to humid farm environment,acid rain and rustlightdep-g....

Custom sizes:Single span 6m/8m/10m/12m;ridge height 2.8–5m;column spacing 3m–4m;pipe wall thickness 1.2–3.0mm optional.

Load capacity:Standard design bears wind load up to 150km/h and snow load 0.3–0.5kN/㎡,stable for plain,coastal and hilly areas.

Gutter system:Integrated galvanized rain gutters between spans for centralized drainage,avoid roof leakage and field waterlogging.

2.2 Covering Film Options

PO Polyolefin Film

Top anti-fog&anti-dripping performance,light transmittance≥90%,UV anti-aging,service life 3–5 years,the most popular choice for commercial farms.

PE Polyethylene Film

Cost-effective,light transmittance 82%–88%,service life 2–3 years,suitable for low-budget projects.

Double-layer Inflatable Film

Extra heat insulation for cold northern regions,cuts winter heating consumption by over 30%.

All films diffuse sunlight evenly to prevent crop sunburn and reduce plant diseases caused by water condensationshinetechg....

3.Optional Full Automatic Supporting Systems

All devices can be separately equipped or integrated into one PLC intelligent control cabinet:

Cooling System:Exhaust fan+water cooling pad to rapidly lower indoor temperature in hot summer

Ventilation System:Electric top roll-up vent+side film rolling vent,natural air exchange to adjust humidity and CO₂density

Shading&Insulation:External sunshade net for summer cooling;internal thermal screen for winter heat preservation

Irrigation System:Drip irrigation,sprinkler irrigation,water&fertilizer integrated machine for automatic nutrient supply

Auxiliary equipment:Heating boiler,CO₂generator,seedling bed,environmental sensor,intelligent control system

4.Core Advantages

High land utilization rate

Shared gutters and side walls eliminate gaps between separate tunnels,land utilization ratio exceeds 85%,greatly expand actual planting area with the same plot of land.

Stable internal microclimate

Large enclosed space avoids sharp temperature changes.Cooling,ventilation and shading equipment run uniformly across the whole greenhouse,ensuring consistent light,temperature and humidity for synchronized crop growth and stable yield.

Convenient mechanized production&labor saving

Unobstructed wide interior allows tractors,transplanters and picking trolleys to pass freely,ideal for large-scale intensive farming and labor cost reduction.

Lower investment&maintenance cost

Compared with glass or PC board multi-span greenhouses,film covering and steel frame save 40%–60%total investment;film replacement is simple and low-cost without complex construction work.

Full modular customization

Span width,ridge height,total length and supporting equipment can be adjusted according to local climate,crop varieties and customer budget,one-stop design for nurseries,agricultural industrial parks and research bases.

5.Application Fields

Commercial vegetables:Tomato,cucumber,pepper,leaf lettuce

Cut flowers&potted ornamental plants:Rose,carnation,orchid

Seedling breeding:Fruit tree seedlings,vegetable plug seedlings

High-value fruits:Strawberry,grape,melon

Hydroponic&aeroponic factory agriculture

Sightseeing picking gardens,modern agriculture demonstration zones,agricultural research labs
