Thailand customers purchased more than 3,400 of our flat sawtooth film greenhouses. The length of the greenhouse is 48 meters and the width is 36 meters. Height 7 meters, 2 sets of greenhouses for growing cannabis. This greenhouse has an internal sunshade system, a fan wet curtain cooling system, a top-opening window ventilation system, a circulation extension system and a fill light system. This greenhouse was built in 2022 and has been in use for 3 years. Everything is running well. Customers in Thailand purchased our zigzag greenhouse for growing cannabis. Due to the hot weather in Thailand, all zigzag top ventilated membrane multi-span greenhouses are the first choice for Thai customers. 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 black shading 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.

Plastic greenhouse structure form 1. The dome structure is the most commonly used building shape of plastic greenhouses, but there are many structural forms that make up this building shape. This kind of greenhouse has a simple structure, clear stress, and large amount of materials. It is widely used in areas with small wind loads. The characteristic of this form of greenhouse structure is that it has horizontal tie rods, which affects the internal space of the greenhouse to a certain extent and limits the height of the greenhouse. For this reason, an improved roof beam structure came into being. In fact, the existence of horizontal tie rods can not only reduce the horizontal thrust of the arch rods on the columns, but also provide convenience for indoor installation of sunshade curtains, circulation fans, and hanging crops. Another form is to use the Venlo-type glass greenhouse structure, fully consider the role of horizontal tie rods, and evolve it into a horizontal truss, which not only facilitates the installation and hanging of indoor equipment, but also greatly simplifies the upper arch. Like the traditional Venlo-type greenhouse, two or three small roofs can be installed on the horizontal frame, which not only greatly reduces the cross-sectional size of the arch, making the installation more convenient and faster, but also makes the indoor lighting fractal more uniform.

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.

Our company undertakes the construction of the Modern Agricultural Science and Technology Industrial Park project in Lanshan District, Linyi. The park covers a total area of ​​300 acres.
