Protective coating systems for corrosion protection of steel structures
Part 8. Create and maintain technical specification development
1 Scope
GB/T 30790 in this section discusses the use of protective coating systems for corrosion protection of steel structures when technical specifications development.
Involved in the workshop or on-site maintenance and new paint and corrosion protection of individual workpieces. This section concerns exposure to different stress corrosion ring
Defense. (indoor, outdoor, immersed in water or buried in the soil, as well as special or high temperature stress generated by China, for example) of the steel structure under ambient conditions
Corrosion protection. Therefore, the durability of different ranges need to be considered.
This section also includes a hot-dip galvanizing, metal spraying, electro-galvanized or powder galvanized steel surface and painted steel surface
Protection.
Appendix B describes the assessment of corrosion protection and construction quality of the protective paint system performance reference surface. Appendices C and D to mention
A detailed flowchart for planning new and maintenance painting protection, it should be considered in the preparation of technical specifications.
If there is extreme stress corrosion or high temperature conditions exist, or protective coating system applied to other substrates, for example, or non-ferrous metals
Concrete, in the preparation of the technical specifications of these factors should also be considered. GB/T 30790 in this section can also be used as guidance in this case.
