In the field of use of metal structures, the most pressing issues are those that relate to a decrease in the complexity of the production process and the work of installation work, saving metal, etc. To protect the metal from corrosion, it must be stored in a dry place well protected from moisture. A good medium for storing metal structures is a medium with air humidity below 60%. It is unacceptable to storage products near salts and gases, which are sources of the release of aggressive media. To protect metal structures, different products are used, which provide their reliable protection against corrosion during operation.
