Most of the sunshine board greenhouses are Venlo type, adopt the one-cross and multi-top structure, and are characterized by the modern appearance, stable structure, elegant form, fluent vision, excellent insulating property, moderate light transmittance, many rainy slots, large span and drainage and strong wind resistance ability. They are suitable for the region with larger wind force and rainfall. 

The sunshine board greenhouse is characterized by good transmittance and low coefficient of heat conduction. Since the sunshine board is light in weight, long in service life and large in tensile strength, so the single steel rib structure could meet the requirements for wind resistance and snow resistance. It is the preferred product to replace the original plastic film greenhouse and glass greenhouse at present by virtue of long service life, elegant appearance and reduction of repeated construction and investment.  

The cover materials of the sunshine board greenhouse are the polycarbonate polypropylene hollow sheet. Both the dual-slope grand-proof structure and the arch structure are adopted. The hot galvanizing steel profile framework is adopted. It is characterized by the light structure, resistance to impact, anti-condensation (anti-condensation coating process), good load performance and good thermal insulation property. It is durable in use, with elegant appearance. Compared with other cover materials, the greenhouse could save over 40% energy. 

Greenhouse materials 

Main structure of greenhouse adopts the cold-reduced hot-galvanizing pipe, the ridge is connected by the herringbone hot galvanizing bolt, with good antiseptic property, and the specialized aluminum alloy section are used as the surrounding framework. 

Main configuration 

The equipment such as inside and outside sunshade, slide window for ventilation, and nappe fan for cooling, etc. could be configured. For other equipment, the users could select the corresponding configuration according to the plantation demand. 

The life of subject is over 20 years. 

The roof is covered by the ultraviolet-proof and anti-condensation Polycarbonate polypropylene hollow sheet, while the wall in four faces is covered by the Polycarbonate polypropylene hollow sheet or glass according to the general requirement. Based on the difference of regional climate condition, in some cold areas (such as Jilin, Heilongjiang, etc.), the north wall is covered by the thermal insulation composite panels, and the sash window could be installed to enhance the ventilation area of greenhouse. 

Greenhouse specification 

The span of sunshine board greenhouse could be divided into 9.6m Venlo-type greenhouse and 10.8m and 12.  

The eaves height could be divided into 3.0m- 5.0m. 

The column spacing could be divided into 4.0m, 6.0m and 8.0n. 

Wind load 0.5KN/m2 

Snow load 0.3KN/m2 

Dead load of greenhouse: 15㎏/㎡ 

Maximum rain discharge amount of greenhouse: 140㎜/h
