Single Layer Agricultural Greenhouses

Single Layer Agricultural Greenhouses

Single lay mean coveing one layer film on the greenhouse frame.  this greenhouse with low cost. 

PO film is 150 microns, with UV , and anti drip, warranty life time is 5 year. 

Agricultural greenhouses for planting vegetables, fruits and flowers are very good in whole year to keep the right temperature and humidity for crops growing deamand. 

Alway design shading net and ventilation and cooling system for greenhouse. 

greenhouse frame also have some different as the local wind , snow, and rain is defferent.

This film greenhouse project includes greenhouse foundation, main frame system, ventilation system, covering system, external shading system, power distribution system, etc. 1.2. Greenhouse performance index: (1) Wind resistance load: 0.8KN/㎡ (2) Snow resistance load: 0.6KN/㎡ (3) Suspended load: 0.5KN/㎡ (4) Maximum rain discharge: 140mm/h (5 ) Greenhouse: Dome type multi-span film greenhouse.

The top of the greenhouse is covered with a single layer of high-quality 15-filament film imported from Japan; the surrounding area is covered with imported 15-filament film, which has better thermal insulation performance.

Main Column: 100×50×2.5mm hot-dip galvanized rectangular tube.

Vice Column: 50×50×2.5mm hot-dip galvanized rectangular tube.

wind Column: 30×50×2.0mm hot-dip galvanized rectangular tube.

Aich pipe : 32×2.0mm hot-dip galvanized round tube.

Longitudinal pipe : 25×1.5mm hot-dip galvanized round tube.

Gutter: 2.0mm cold-formed hot-dip galvanized sheet is used, and the large section can resist 140mm/hour of rainfall. Downpipe: Anti-aging UPVC pipe, Ф110 mm.

The connection and fixing parts mainly use M8, M10, M12 hexagon head bolts that meet the GB5782 standard (grade 4.8) and the corresponding hexagonal nuts that meet the GB6170 standard, and are hot-dip galvanized. The service life of the main structure of the greenhouse is 25 years.

All steel structure materials in the greenhouse are hot-dip galvanized, and the thickness of galvanizing is 0.07-0.10mm. Other standards of hot-dip galvanizing adopt the national standard "GB/T13912-2002"

Natural ventilation is a relatively economical ventilation method. It uses the temperature difference to realize the air exchange inside and outside the greenhouse to achieve the purpose of reducing the temperature and humidity in the greenhouse. In the absence of a CO2 fertilization system, natural ventilation can also be used to supplement CO2 in the greenhouse. Both sides of the greenhouse and the roof use manual roll film to open the window, and the manual roll has a self-locking device

The main structure of the greenhouse external shading system is directly arranged outside the greenhouse. The middle column is fixed on the greenhouse water ditch with a height of 3.0m. The cross beam adopts a truss with upper and lower chords of 30×30×1.5mm hot-dip galvanized square tubes, and the longitudinal beam adopts 50×50×2.0mm hot-dip galvanized tubes.

The double-layer curtain line adopts domestic transparent polyester curtain line, and the deformation is small. The spacing between the supporting curtain lines is 0.5 meters, and the spacing between the pressing curtain lines is 1 m.

Black shading net, shading rate of 80%-85%, shelf life of 3 years, life of 5 years

Distribution System mainly controls all the electrical equipment of the external shading system of the greenhouse. It has double protection of thermal overload and open circuit
