Greenhouse major types: plastic greenhouse structure. The main structure. Plastic greenhouses main structure is generally used for hot-dip galvanized steel main load-bearing structure, industrial production, on-site installation. Because of their light weight plastic greenhouse, resistance to wind, snow load is weak, so the overall stability of the structure must be fully considered, in general or in the interior of the second cross the bay to set the second vertical bracing, in the greenhouse the external structure and the roof space should also consider setting up the necessary support. Best supporting oblique (oblique rod) anchored to the base cost of Greenhouse sun panels, forming a space force system. Height and north-south span greenhouse: height and north-south span of Greenhouse construction Greenhouse sun panel should be set according to the local latitude. Because height and angle of the sun determines the span of Greenhouse Greenhouse lighting board surface, angle light plane around the sun but also the size of the angle of incidence. To ensure that there is a greater incidence rate of sunshine, it should be less than 40 degrees angle of incidence. Solar elevation angle, its location decision latitude, different in different parts of its latitude, its different solar elevation angle.
