Glass Multi-span Greenhouse
(1) Brief Introduction
Glass greenhouse, is mainly covered by glass, which has high translucency, suitable for the plants of great demanding for sunlight. Among the cultivation facilities, glass greenhouse, as the facility of longest service life, is fit for many places and nearly all kings of climates.
Heating problems in winter can be solved by many kinds of heating methods. The cost of the power consumption is modest and mostly accepted. The floor space, material utilization amount and usage mood can be defined by the designing and demands from clients.
(2) Structure and Configuration
The skeleton is made by rectangular steel tubes that are cold-rolled, two-sided hot-galvanizing.
The greenhouse can be collocated with some necessary systems, such as, inside & outside shading systems,side & roof ventilation system, heating & cooling systems,etc.
The covering materials include two kinds of hollow glass. The specifications are 4mm+9mm+4mm and 5mm+6mm+5mm.
The inlay materials of glass are the appropriate aluminum alloys and the adhesive tapes are used to tighten the contact area.
(3) Service Life:
The main body can be used for more than 20 years.
(4) General Technical Parameters
Resistance to Wind Load: 0.6kN/m2.
Resistance to Snow Load: 0.5kN/m2.
Constant Load: 15kg/m2.
Maximum Rate of Rain Drainage: 140mm/h.
(5) Characteristics
good and stable light transmission (more than 80%), great lighting performance and even illumination.
the spacious and bright inner part, large operating space and high availability, able to increase the number of spans.
steam-proof and condensation-Proof, strong aging resistance and drainage.
