A Qatari customer purchased our 3,000-square-meter film greenhouse. The length of the greenhouse is 64 meters and the width is 54 meters. Height 6 meters, used for hydroponic lettuce. This greenhouse is equipped with an internal and external sunshade system, a fan wet curtain cooling system, a top-opening window ventilation system, and a circulation extension circulation system. This greenhouse was built in 2020 and has been in use for 5 years. Everything is running well.

Customers in Africa purchased our zigzag greenhouses to grow vegetables. This greenhouse is 60 meters long and 40 meters wide. The greenhouse frame is hot-dip galvanized and covered with a 3-layer PO tape scattering anti-drip film with a 5-year warranty. Equipped with internal shading system and top ventilation system. This ventilation system is suitable for use in tropical and rainy areas. Top ventilation helps the hot air inside the greenhouse escape to the outside of the greenhouse. At the same time, this top ventilation method does not need to be closed even on rainy days. At the same time, this kind of greenhouse has a very good cost performance, so it is recognized and chosen by many customers.

sawtooth roof greenhouses are divided into three types: fully serrated, sharp serrated and blunt serrated according to the different forms of roof serrations. The corresponding structural forms are also different. The sawtooth openings of the fully sawtooth roof are set up vertically from the roof ridge to the gutter. According to the shape of the roof, fully sawtooth roof greenhouses can be divided into pitched roof sawtooth greenhouses and arched roof sawtooth greenhouses. Regardless of the roof type, the greenhouse structure generally connects the columns directly to the greenhouse roof, and forms a slope roof or semi-circular arch roof from the roof ridge to the gutter. The sawtooth opening of the sharp sawtooth roof is from the ridge of the greenhouse to the middle of the greenhouse roof. If the greenhouse ridge is in the middle of the span, an asymmetrical greenhouse roof with high and low ridges can be formed. When the roof ridge is in the middle of the span, vertical poles can be set on the horizontal tie rods of the columns to connect with the left and right roof arches to form mid-span sawtooths. Columns can also be set up in the middle of the greenhouse span, and the tops and middle upper parts of the columns are connected to the two columns respectively. The roof arch bars on the side form saw teeth in the middle of the span. The former has fewer indoor columns and a large working space, while the latter has high structural strength. The greenhouse arch pole can completely adopt the arch pole method of the round arch roof.

The construction investment per unit of facility area in a single span greenhouse is the lowest. However, the investment in heating and ventilation systems is higher in single span greenhouses because each greenhouse needs to have separate heating and ventilation equipment. Once the total production area of the greenhouse exceeds 05 acres, the cost of labor and mechanization of production in single span greenhouses is usually higher than in continuous greenhouses because it is difficult, though not technically impossible, to transport crops in single span greenhouses using equipment such as rails, conveyor belts, and mobile cutting beds.

. Single-span greenhouses take up more land than continuous greenhouses because space must always be left between each greenhouse, and if the building site is a valuable building land resource, the low-cost advantage of a single-span greenhouse compared to the land-saving advantage of a continuous greenhouse is close to nothing when determining the greenhouse form for the remaining building site after all the other individual building facilities that must accompany it have been planned and laid out.

If crop production requires a high level of greenhouse environmental control and operational automation, such as the production of bedding plant hole seedlings, a continuous greenhouse may be considered.

When pests or diseases are encountered, they are easily isolated using a single span greenhouse.

If the field layout needs to be changed, a single-span plastic greenhouse is easier to relocate than a continuous greenhouse.
