Openable roof film greenhouse is a new type double layer greenhouse, it is combined the advantages of general greenhouse, shading house, net house, and use folding flexible covering material prevent rain and wind. Companied with shading system, the greenhouse can decrease temperature and control sunlight. No gutter needed in this kind of greenhouse and can maximize the use of natural light and heat resources, ventilation area can reach 100% of projected area, light transmittance can reach 90%. Better ventilation, decrease temperature, ability to use light and low cost than normal film greenhouses. Open-roof greenhouses are becoming more popular with commercial growers. The open-roof greenhouse offers maximum natural light and ventilation to the greenhouse crop. Similar in construction to that of the Venlo, the open-roof is constructed of two or more roof peaks per greenhouse bay. Each roof section is hinged at the gutter and is connected to a rack-and-pinion or push-pull drive system. Computer-controlled motors push the roof sections open, in effect making the entire roof into a vent. Open-roof greenhouse designs can often control the greenhouse temperature sufficiently without exhaust fans. Natural ventilation works primarily on the principle that wind blowing across a roof vent will create a low-pressure zone that will suck the air out of the greenhouse while letting air in the side vents. the biggest is the improvement to crop quality and production efficiency due to the improved range of environments they provide.

Gold sunshine has won numorous patent rights in greenhouse field and occupy the leading positon of the greenhouse.
Strong Technology Team: Professional R&D center guarantee top quality and advanced reliable design for each project.
Personal Custom: All the greenhouse design is made according to customers' local climate condition and requirements.

1. Simple structure: galvanized steel frame + plastic film cover + side ventilation.

2. Easy assembly: The precast steel pipe can be easily connected through some fasteners.

3. Large internal space, easy operation and maintenance.

4. The tunnel greenhouse cost is not high, you can get high yield with low input.

5. Multi-purpose: You can use a small tunnel greenhouse in your garden as a garden greenhouse, or you can have a large scale for your farm.

At present, there are more and more greenhouses of various types, there are simple greenhouses, but also more complex and more scientific and technological sense of intelligent greenhouse shed. In many greenhouses, many people like to build greenhouse. This kind of shed has been welcomed by more and more people with its unique advantage. Just like our present building, there are single-family buildings and several units of buildings. Our ordinary greenhouse is equivalent to a single-family building, and now the multi-span greenhouse is actually equivalent to several units of buildings. This should be better understood. Speaking of this greenhouse, in fact, we need professional manufacturers to build, we ordinary people are very difficult to build a qualified greenhouse. If we want to build a qualified greenhouse, we must find a good greenhouse in charge of construction, so that we can be more assured.
