Because this kind of company soon entered the field of refrigerated transport vehicle manufacturing, its design scheme and production technology level are not mature. For them, the purchase of bolts is not very critical. They do not understand the difference between general bolts and moisture-proof rivets specially used for freezing and cold storage in refrigerated transport vehicles, resulting in general application After being used for a period of time, the bolt refrigerated transport vehicle not only consumes a lot of energy, but also has a short service life.

At present, there are few companies using moisture-proof metal drawing bolts in all directions in China, so the problems mentioned above are common. However, the copper iron rivet cold chain transportation equipment company has applied this kind of moisture-proof metal drawing bolt in an all-round way. The professional and technical personnel all know the design scheme of refrigerated container. Stainless steel closed rivets are not antirust treatment of the problem, whether the bolts can be antirust treatment is a very vivid problem, that is, in the whole process of production and manufacturing of refrigerated transport vehicles, the bolt materials used must be rust proof treatment, aluminum and metal materials can be used, that is, steel bolts can not be used.
