Something about tunnel greenhouse
Tunnel greenhouse is one of the most widely used greenhouses. Its structure is relatively simple with low cost. Tunnel greenhouse can accumulate heat by light, so that the average indoor temperature is higher than outdoor temperature for a long time. At the same time, the film greenhouse also has the function of resisting bad weather and insect pests. With the help of tunnel greenhouses, growers can harvest crops about a month earlier in spring and one month longer in autumn. In this way, the growers can not only spend about two months more planting time each year, but also avoid the time for others to sell fruits and vegetables on the market, so as to obtain higher economic benefits with better quality products.
Tunnel greenhouse is one of the most widely used greenhouse series. Usually, we also call it as Film Greenhouse, Polytunnel, and Plastic Greenhouse. It is determined by its appearance. Single-arch film greenhouse needs less space and is easy to build. It is often the preferred choice for individual growers.
Why we are better
Different film covering materials have different transmittance. Transparency is an extremely important index in greenhouse covering materials, because it directly affects crop yield. Through our years of research, we found that for every 1% increase in the transmittance of greenhouse, the yield of crops planted in greenhouse will also increase by about 1%. In order to maximize the benefits of users, we selected PEP films with a transmittance of 88%. At the same time, ordinary plastic films only have 80% transmittance on the surface in markets. Choosing us, you are choosing 8% more production!
Ordinary plastic film will aging rapidly after sunshine exposure, the product life becomes very short. As a result, growers often need to re-purchase films for coverage, which is both laborious and costly. In order to solve this problem, we add a layer of anti-ultraviolet coating on the film, which can effectively prolong the service life of the film. In non-extreme climatic conditions, the service life of our films can be as long as 5 years.
The interior environment of greenhouse is usually humid and hot. Under this condition, the common steel frame is easy to rust, which affects the appearance and service life of greenhouse. All our frames are galvanized steel, which can perfectly cope with the internal environment of greenhouse and avoid the loss caused by rusting of materials. We can guarantee that our membrane greenhouse frame can last more than 15 years.
