ISO 12944-3:2017涉及设计钢结构的基本标准，以保护涂料系统涂覆，以避免涂层或结构过早腐蚀和降解。它举例说明了适当和不恰当的设计，指出了如何避免涂装系统的应用，检查和维护问题。还考虑了便于处理和运输钢结构的设计措施。

ISO 12944-3:2017 deals with the basic criteria for the design of steel structures to be coated by protective paint systems in order to avoid premature corrosion and degradation of the coating or the structure. It gives examples of appropriate and inappropriate design, indicating how problems of application, inspection and maintenance of paint systems can be avoided. Design measures which facilitate handling and transport of the steel structures are also considered.
