Greenhouse durability

A greenhouse is a high-input, high-output agricultural facility, and its one-time investment is higher than the open-ground production input.
Tens of times or even hundreds of times, the length of its service life directly affects the annual depreciation cost and production efficiency
Benefits, so greenhouse construction must consider its durability.
In addition to the aging resistance of greenhouse materials, the factors affecting the durability of greenhouses are also related to the main structure of greenhouses.
Carrying capacity. In addition to its own strength, the durability of light-transmitting materials is also reflected in the transmittance of the material over time.
To the extent of attenuation, the attenuation of light transmittance is often the decisive factor affecting the service life of light-transmitting materials. Design temperature
The bearing capacity of the main structure of the room is directly related to the maximum years of wind and snow load. General steel structure greenhouse
The service life is more than 15 years, and the design wind and snow load are required to meet the maximum load once in 25 years.
Due to the long-term operation of the greenhouse in a high temperature and high humidity environment, the surface corrosion of the components has affected the greenhouse.
Life is another important factor. For steel structure greenhouses, the main structure of the force is generally thin-walled steel.
It has poor anti-corrosion ability. It must be treated with hot-dip galvanized surface in the greenhouse. The thickness of the coating is up to
Above 150 ~ 200μm, it can guarantee 15 years of service life.
