PC Sheet Agricultural Arched Multi-span Greenhouse For Planter
Product Description
Advantage
(1) High light transmittance and uniform illumination.
Due to the characteristics of the load-bearing structure, the PC board greenhouse greenhouse roof uses PC board with high light transmittance as the lighting material, and at the same time, special aluminum profiles are used as the roof beam, which greatly reduces the cross-sectional size of the roof beam and eliminates roof purlins. And connectors, etc., reduce the shading of the entire roof system, and greatly improve the light transmittance of the entire greenhouse.
(2) The greenhouse has good air tightness.
The PC board greenhouse uses special aluminum alloy and its supporting rubber strips and injection parts as glass inlay members, which greatly improves the hermeticity of the greenhouse.The good hermeticity on the one hand ensures that the greenhouse loses heat due to convection. Lowering, on the other hand, provides conditions for good roof drainage. Because PC board greenhouses often combine a gutter with a small cross section and the roof on both sides of the gutter to form a roof drainage channel for the greenhouse, greatly improving roof drainage efficiency.
(3) Large ventilation area.
The ratio of the roof of the greenhouse with a PC board to the ground is relatively high. Compared with other types of greenhouses of the same span, it can have 2 to 4 pairs of roofs in each span, that is, 2 to 4 ridges and gutters. When the window opening method is adopted, the same ventilation rate as that of other greenhouses in the same span can be achieved. When continuous window opening is adopted, the ventilation rate is doubled. Generally, the ventilation area of a greenhouse with a PC board can reach about 30% of the area of the greenhouse.
(4) High roof drainage efficiency.
Since the number of gutters in each span of the PC board greenhouse is 2 to 4, compared with other types of greenhouses in the same span, the catchment area of each gutter is also reduced by 50% to 83%.
