When building a cold storage, do you choose color steel or stainless steel for the storage board?

　　When building a cold storage, the slab of the cold storage is the core enclosure structure, which directly affects the insulation effect, service life and operating cost of the cold storage. Faced with the mainstream color steel and stainless steel warehouse boards in the market, many builders often fall into the dilemma of choice. Although both of them are commonly used materials, there are differences in performance, cost and applicable scenarios. In the end, which one to choose needs to be comprehensively judged by combining the use of cold storage, environmental conditions and long-term operating requirements. ​

　　From the perspective of corrosion resistance, stainless steel library board has obvious advantages. Its alloy elements such as chromium and nickel can form a stable oxide film on the surface, which can resist moisture, low-temperature condensation and acid-base environmental erosion, and is especially suitable for cold storage where seafood, meat and other products are prone to salt water and blood water, or cold storage located in coastal and high-humidity areas. In this kind of scene, the stainless steel library board is not easy to rust and delaminate, and its service life can reach 15-20 years. However, the surface of color steel warehouse board is protected by galvanized coating and colored paint. If the coating is damaged due to collision and friction, the bottom steel plate is easy to rust in low temperature and high humidity environment, and the service life is usually 8-12 years, so it needs regular inspection and maintenance, otherwise the thermal insulation performance may be affected by corrosion. ​

　　In terms of thermal insulation performance and cost balance, the color steel warehouse board is more cost-effective. Both commonly used core materials are polyurethane or extruded board, and the thermal insulation effect mainly depends on the density and thickness of the core material, and the material itself has little influence on the thermal insulation. However, from the cost point of view, the unit price of color steel warehouse board is about 50%-60% of stainless steel warehouse board. For small and medium-sized food cold storage, fruit and vegetable fresh-keeping warehouse and other scenes with low corrosion resistance requirements, choosing color steel warehouse board can greatly reduce the initial construction cost. However, it should be noted that if the door of the cold storage is frequently opened and closed, the amount of people and goods is large, and the surface coating of the color steel warehouse board is easy to wear, it is recommended to choose thick color paint or add protective film to prolong the service life. ​

　　Moreover, the surface of stainless steel warehouse board is smooth and flat, with no seam dead angle, which is not easy to breed bacteria, and it is resistant to corrosion by cleaning agents. When cleaning, it only needs to be wiped with clean water or neutral cleaning agents, which usually meets the hygiene requirements of medicine cold storage and food processing cold storage. Although the surface of color steel warehouse board can also be cleaned, it is easy to leave stains at the joints, and the coating may fade and scratch after long-term use. For cold storage scenes that need high-frequency cleaning, it is relatively difficult to maintain. ​

　　To sum up, when building a cold storage, you need to choose color steel or stainless steel storage board, or you need to combine the actual needs.

　　What are the differences in the cost of building cold storage with different functions?

　　What are the differences in the cost of building cold storage with different functions? When planning cold chain facilities, one of the problems that business owners are more concerned about is the overall cost of cold storage construction. In fact, the cost of cold storage is not a fixed figure, and its cost difference mainly depends on the functional orientation of the storage body. Different storage requirements, such as storing fruits and vegetables, meat or special medicines, have completely different requirements on temperature, humidity, equipment configuration and materials, which directly determine the final investment amount. Therefore, defining the function is the first step of accurate cost budget. The following will analyze in detail the main differences in the construction cost of several common cold storages.
