Scope

Scope: This document specifies the application fields, general requirements, quality requirements for coating products, performance requirements for coating systems, on-site construction quality assurance, inspection rules, and marking, packaging, and storage of low-surface-treatment protective coating systems for coastal steel structure maintenance. This document applies to various coating products and their supporting systems that provide corrosion protection for steel substrates during maintenance coating. This coating system is primarily used for the protection of coastal steel structures where iron rust or old coatings cannot be completely removed by sandblasting or other methods during maintenance coating, as well as for structures in high-humidity environments that require rust-coated protection. The corrosion environment of coastal steel structures typically belongs to the atmospheric corrosivity grade C4 or C5 defined in ISO 12944-2:2017. Steel structures with a corrosivity grade lower than this can also use protective coating systems that meet the requirements of this document. The performance requirements of protective coating systems used for non-coastal environment steel structure maintenance where conventional rust removal methods cannot achieve Sa21/2 or St3 can also refer to this document.
