Venlo greenhouse

The framework of Wenluo greenhouse is composed of steel frame and aluminum alloy, and the transparent covering material is 4mm thick flat glass. The shape and type of greenhouse roof mainly include multi ridge continuous span type and single ridge continuous span type.

The standard ridge span of multi span text greenhouse is 3.2m or 4m, the span of single room greenhouse is 6.4m, 8m and 9.6m, and the span of large span can reach 12m and 12.8m. In the early stage, the column spacing of greenhouse was 3 ~ 3.12M. At present, 4 ~ 4.5m is more used. The traditional roof ventilation window of this type of greenhouse is 0.73M wide and 1.65m long: at present, the glass width is about 1m, and the commonly used is 1.25m. Taking 4m ridge span as an example, the length of ventilation window glass is 2.08 ~ 2.14M. Similarly, the height of the drain is gradually adjusted over time. At present, the column height of this type of greenhouse is 2.5 ~ 4.3m, the ridge height is 3.5 ~ 4.95M, and the angle of glass roof is 25 °. The standard span of single ridge multi span greenhouse is 6.4m, 8m, 9.6m and 12.8m. In the case of multiple span greenhouse and single ridge greenhouse, the ventilation rate is the same.
