Connected Multi-span Film Greenhouse

1.Product Overview

Connected Multi-span Film Greenhouse,also named gutter-connected plastic greenhouse,is a mainstream large-scale controlled agriculture facility for modern commercial farmingfcgreenhou....It links multiple single arch tunnel units side by side via shared drainage gutters to form a seamless,spacious continuous planting area,completely different from scattered independent polytunnels.

Supported by hot-dip galvanized steel skeleton and covered with high-functional agricultural PO/PE/EVA film,this greenhouse balances low construction cost,flexible layout and full climate controllability.It supports full set automatic supporting systems and mechanized farming,widely recognized by growers for vegetables,flowers,seedlings,fruits and hydroponic cultivation worldwideshinetechg....

2.Core Structural Configuration

2.1 Steel Frame System

Main material:Heavy-duty hot-dip galvanized round steel pipe,passivation anti-rust treatment,service life≥15 years,resistant to humid agricultural environment,acid rain and corrosionSAINPOLY.

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

Load capacity:Standard design withstands wind load up to 150km/h and snow load 0.3–0.5kN/㎡,stable in plain,mountain and coastal regionslightdep-g....

Gutter connection:Integrated hot-dip galvanized drainage gutters between spans,centralized rainwater collection&discharge,prevent roof water leakage and ground waterlogging.

2.2 Covering Film Material

Optional high-transmission functional agricultural film:

PO Polyolefin Film:Best anti-fog&anti-dripping,light transmittance≥90%,anti-UV aging,service life 3–5 years;

PE Polyethylene Film:Cost-effective,82%–88%light transmission,2–3 years service life;

Double-layer inflatable film:Extra thermal insulation for cold northern areas,cut winter heating energy consumption by 30%+SAINPOLY.

All films block harmful ultraviolet rays,diffuse sunlight evenly to avoid crop sunburn,and reduce mold diseases caused by condensed water drops.

3.Optional Full Supporting Automatic Systems

All systems can be equipped independently or integrated into one intelligent control cabinet:

Cooling System:Exhaust fan+water cooling pad core unit,quickly lower indoor temperature in hot summer;

Ventilation System:Electric top rolling ventilation+side rolling film ventilation,natural air circulation to adjust humidity and CO₂concentration;

Shading System:External sunshade net for summer heat insulation;internal thermal insulation screen for winter heat preservation;

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

Auxiliary options:Heating boiler,CO₂generator,seedling bed,rolling machine,intelligent environmental sensor&PLC automatic control system.

4.Outstanding Advantages

Ultra-high land utilization rate

Shared gutters and side walls eliminate wasted gaps between single greenhouses,land usage efficiency reaches over 85%,greatly expand actual planting area with same plot of landfilmgreenh....

Stable uniform internal microclimate

Large enclosed space avoids drastic temperature fluctuation.Ventilation and cooling equipment runs uniformly across the whole greenhouse,every crop gets consistent light,temperature and humidity to guarantee synchronized growth and consistent yield.

Convenient mechanized operation&labor saving

Wide unobstructed interior space allows walking tractors,transplanting machines and picking trolleys to pass freely,suitable for large-scale intensive farming,drastically cut manual labor cost.

Lower investment&maintenance cost

Compared with glass or polycarbonate multi-span greenhouses,film covering material and supporting steel frame cost 40%–60%less.Film replacement is simple and low-cost without complicated construction worksQingzhou J....

Strong modular customization ability

Length,span,height and supporting equipment can be adjusted fully according to local climate,crop type and customer budget,one-stop customized design for small nurseries,large agricultural industrial parks and scientific research bases.
