1. Multi-span all-glass greenhouses
Multi-span glass greenhouses refer to greenhouses with glass as lighting materials on the top and sides, which are a type of greenhouse. Among cultivation facilities, multi-span glass greenhouses have the longest service life and are suitable for use in a variety of regions and various climatic conditions.
This type of greenhouse is the most complex and high-end type of greenhouse, generally with a Venlo structure and three or four spires in one span. The top of the multi-span all-glass greenhouse is generally covered with 5mm tempered glass (it can also be designed as double-layer hollow tempered glass), and the surroundings are generally covered with single-layer or double-layer hollow glass (tempered or float glass, depending on the customer's choice). The configured system generally includes: main hot-dip galvanized steel frame, dew collection system, top and surrounding covering materials, aluminum profile system, external shading system, internal shading and insulation system, top opening window system, water curtain fan cooling system, sprinkler irrigation system, movable seedling bed system, outward-turning window system, power distribution system, drainage system, etc.
2. Multi-span greenhouse with full PC solar panels
The appearance of the multi-span greenhouse with full PC solar panels is based on the Dutch Venlo type multi-span greenhouse with full glass, but the top and sides are covered with double-layer PC hollow solar panels, which is a multi-span greenhouse structure.
The structure of this type of greenhouse is basically the same as that of a full glass greenhouse, both are Venlo structures, except that the top and sides are covered with full PC sun panels, generally 6-8mm hollow anti-aging and anti-drip PC sun panels (the specific thickness needs to be negotiated with the customer). The configured system is the same as that of a full glass greenhouse: the main body hot-dip galvanized steel frame (surface spraying can be done separately), dew collection system, top and surrounding covering materials, aluminum profile system, external shading system, internal shading and insulation system, top window system, water curtain fan cooling system, sprinkler irrigation system, external flip window system, movable seedling bed system, power distribution system, drainage system, etc.
3. Multi-span PC sun panels - glass greenhouses
This type of greenhouse is currently the most commonly used multi-span greenhouse type, and also belongs to the Venlo structure. In order to reduce the weight of the top, the top covering material is replaced with 6-8mm PC sun panels, and the surroundings are covered with single-layer or double-layer insulating glass (the specific thickness needs to be negotiated with the customer). The configuration system is the same as the full glass greenhouse: the main body hot-dip galvanized steel frame, dew collection system, top and surrounding covering materials, aluminum profile system, external shading system, internal shading and insulation system, top opening window system, water curtain fan cooling system, sprinkler system, external flip window system, movable seedling bed system, power distribution system, drainage system, etc.
4. Ecological restaurant greenhouse and flower market greenhouse (leisure greenhouse)
The two types of greenhouses are essentially Venlo structures, but their main purpose is to be used as greenhouses for restaurants in ecological park complexes or greenhouses for flower markets. Now more and more ecological park greenhouses and flower market greenhouses are being built, and the greenhouse structures used are all high-end multi-span greenhouses. The configuration system is the same as that of the full glass greenhouse: the main body hot-dip galvanized steel frame, dew collection system, top and surrounding covering materials, aluminum profile system, external shading system, internal shading and insulation system, top opening window system, external flip window system, water curtain fan cooling system, power distribution system, drainage system, etc. This type of greenhouse can be arranged with gardening, bonsai, vegetable walls, and exhibitions of various cultivation methods. It can be used for planting, visiting, leisure, entertainment, catering, sales, exhibitions, teaching, training, scientific research, and can also be used for greenhouse yoga, which is a cross-border use.
5. Multi-span greenhouse
Multi-span greenhouse refers to a greenhouse with a single span and multiple spans. The roof can be arched, pointed, sawtooth, half-slope, etc. It is a type of greenhouse with multiple water tanks and large span structure. It is also the most widely used greenhouse. It is mostly used for leafy vegetables, fruits and vegetables, seedlings, and professional seedlings and planting of cruciferous flowers. The top and sides of this type of greenhouse are covered with a single-layer film or a double-layer film, and the windows are covered with insect-proof nets or bird-proof nets. The span of the multi-span greenhouse is generally 6-9.6 meters, the bay is generally 4 meters, the shoulder height is generally 3-6 meters, the top height is about 5-8 meters, and the height of the external shading system is 5.4-8.5 meters (if the external shading system is configured). The configured systems include: main hot-dip galvanized steel frame, top and surrounding covering materials, external shading system, internal shading and insulation system, top window system, water curtain fan cooling system, movable seedbed system, irrigation system, side window system, growth line system, power distribution system, drainage system, etc.
6. Simple multi-span film greenhouse.
This type of greenhouse is a simple version of the multi-span film greenhouse. It does not need to be configured with so many systems. It is just a simple steel frame and covering materials. Roll-up film ventilation windows can be appropriately arranged on the top and around the sides.
7. Single arch shed
Single arch shed, commonly known as cold shed, is a simple and practical protected cultivation facility. It is widely used by growers in various places because of its easy construction, convenient use and low investment. The main purpose of this simplest single arch shed is to allow vegetables and fruits to be "early in spring and late in autumn" to achieve staggered listing and obtain higher returns.
Most arch sheds are made of hot-dip galvanized steel pipes and covered with plastic film to form an arched shed for growing vegetables. This single arch shed can provide vegetables earlier or later, increase the yield per unit area, and can simply prevent natural disasters, making it convenient for growers to supply fresh vegetables in the early spring and late autumn off-season.
