What is the difference between civil cold storage and prefabricated cold storage?

　　Civil cold storage and prefabricated cold storage each have their own unique advantages and disadvantages. Choosing which one is more suitable depends on the specific use needs and conditions. The following are the main differences between the two:

　　Characteristics of civil cold storage:

　　1. Structural stability: The structure of civil cold storage is fixed, usually composed of building materials such as concrete and masonry, so it has high load-bearing capacity and stability.

　　2. Thermal insulation performance: The insulation layer of civil cold storage is usually formed by spraying materials such as polyurethane, which has good thermal insulation performance.

　　3. Strong adaptability: Civil cold storage can be designed according to terrain and specific needs, and is suitable for a variety of different environments and sites.

　　4. Long-term durability: Civil cold storage has a long service life. Once built, it can be used stably for a long time.

　　5. Construction cost: The construction period of civil cold storage is long, and the initial investment is large, but in the long run, the maintenance cost is relatively low.

　　Features of prefabricated cold storage:

　　1. Easy and quick installation: prefabricated cold storage uses standardized components, which is easy to assemble on site, has a short installation period, and can be put into use quickly.

　　2. Flexible combination: The size and structure of the cold storage can be flexibly adjusted according to user needs, and it has strong adaptability.

　　3. Light weight: The materials used in prefabricated cold storage are relatively light, which is convenient for transportation and installation.

　　4. Corrosion resistance and aging resistance: The materials used, such as polyurethane, have good corrosion resistance and aging resistance.

　　5. Low initial investment: Compared with civil cold storage, the initial investment of prefabricated cold storage is relatively low, but the long-term maintenance cost may be high.
