The past and present life of Venlo type glass greenhouse

The Venlo-type multi-span greenhouse is the most commonly used greenhouse structure in the world. Since the application of Venlo-type multi-span greenhouses has been very widespread around the world, what is a Venlo-type multi-span greenhouse? What are the characteristics of Venlo-style greenhouses? Lets take a closer look below.


The main frame structure of the Venlo-style multi-span greenhouse is made of three-ridge hot-dip galvanized steel structure with good anti-corrosion performance. The service life of the main body is more than 20 years.


Covering materials: Covering materials are mainly divided into anti-reflection coated glass, double-layer float glass or tempered glass, PC solar panels, etc. Greenhouses are generally covered with UV-resistant, anti-condensation polycarbonate hollow panels (PC solar panels) or anti-reflective glass, and a special hot-dip galvanized steel frame, which has the advantages of good lighting, heat preservation, economy and durability, and strong resistance to impact and damage. It can also be covered with different materials according to the differences in climate conditions and specific design requirements in the customer's region.


Main configuration: The greenhouse can achieve fully automatic control, and can be configured with internal and external sunshade systems, internal insulation systems, skylight and side window systems, wet curtain fan cooling systems, heating systems, sprinkler and irrigation systems, etc. Users can customize the greenhouse according to different planting varieties and usage. Appropriate configuration is required.


Application fields of Venlo type multi-span greenhouse: It can be used as a production greenhouse for growing vegetables and flowers, and as a seedling greenhouse for vegetables and flowers.


Glass greenhouse is a new type of architectural style that gradually developed after the industrial revolution. The word "Venlo" comes from the name of a small town in the Netherlands, where the Venlo-type greenhouse was born in the 1950s. After more than 50 years of development, this kind of greenhouse has been widely used in countries around the world, becoming the most widely used and most frequently used form of glass greenhouse in the world.


Venlo type glass greenhouse structure advantages: no purlin roof system, the load borne by the glass acts directly on the greenhouse longitudinal gutter, and the gutter directly transmits the force to the columns or roof beam nodes. Therefore, the gutter bears the uniform force and concentrated maintenance load from the roof system, and the external force borne by the roof beams is mainly transmitted from the gutter.


High roof drainage efficiency: Since there are 2 to 4 gutters per span of the Venlo-type greenhouse, compared with other types of greenhouses with the same span, the water catchment area of each gutter is reduced by 60% to 79%.


Venlo type glass greenhouse supporting systems: external electric shading system, internal electric shading system, internal insulation curtain system, top electric window opening system, fan + water curtain forced ventilation cooling system, water curtain electric outward-turning window system, internal heating Equipment, etc. (selected according to application requirements)


Venlo type glass greenhouse application scenarios: vegetable and flower planting and seedling cultivation, aquaculture greenhouses, leisure and sightseeing greenhouses, ecological picking garden greenhouses, ecological restaurant greenhouses, leisure club greenhouses, high-tech display greenhouses, etc.


The main structure is a hot-dip galvanized light steel structure, and the covering material is glass or PC board. Systems such as natural ventilation, fan wet curtains, heating system, irrigation, fertilization, light supplement, and automatic control can be configured according to the needs of customers or crop growth.


The Venlo-type greenhouse has fewer columns and a large space, making it easy to arrange crop planting. The roof adopts the form of a small spire and has a small top space, which can reduce energy consumption for cooling in summer and heating in winter. The top adopts a "several" steel structure. , can effectively reduce the impact of greenhouse condensation on crops. If the covering material is glass, the greenhouse has good light transmittance, heats up quickly, is transparent and bright indoors and outdoors, and is beautiful, suitable for high-end flower planting, scientific research, and visits; if the covering material is PC board, the greenhouse has good thermal insulation performance and impact resistance. Excellent, can resist the impact of ice, suitable for the planting and scientific research of medium and high-end flowers and vegetables.
