What are the types of cold sheds
Most of the cold sheds are used in the south. The cold shed itself is more suitable for the rainy weather in the south. It is a simple plastic greenhouse with low cost. The cold shed has poor thermal insulation, but has a better moisturizing effect. The plastic greenhouse makes full use of solar energy and has a certain thermal insulation effect. The temperature and humidity in the cold shed can be adjusted within a certain range by rolling the film. Therefore, the cold shed is only suitable for outdoor use.
1. Cold shed with galvanized steel pipe
Galvanized steel pipes are equipped with arch rods, end columns and longitudinal tie rods of this structure are thin-walled steel pipes, which are connected by special fixtures to form a whole. All rods and fixtures are made of hot-dip galvanized anti-corrosion. Rust treatment is a factory-produced industrial product. The cold shed equipped with galvanized steel pipes is anti-corrosion, with high overall strength, strong ability to withstand wind and snow, and a service life of more than 15 years. It is also a relatively advanced greenhouse structure at present.
2. Bamboo and wood structure cold shed
The cold sheds of this structure are similar in different regions, with little differences. The span, length, shoulder height, and ridge height of the greenhouse are basically the same as the shed shape. Moreover, this kind of cold shed is convenient to obtain materials and low cost. It is also easy to build, and it is also a cold shed that we commonly see in rural areas. Its disadvantages are that there are many columns in the shed, high shading rate, inconvenient for flat farming, short service life, and poor resistance to wind and snow loads.
3. Cold shed with welded steel structure
This kind of steel structure cold shed, the arch frame is a flat truss formed by welding steel pipes, steel bars or a combination of the two. It is convenient to use and is a good cold shed facility, but this kind of skeleton is painted to prevent rust and needs to be painted once every 1-2 years, which is more troublesome. If it is well maintained, the service life can reach 6-7 years. .
