GB/T 30790.3-2014 specifies the basic guidelines for the design of steel structures for anti-corrosion painting using protective coatings systems, aiming to avoid premature corrosion and aging of structures or coatings. The standard emphasizes anti-corrosion factors that should be considered at the design stage, such as structural shape, surface preparation, operability of coating construction and maintenance, etc. For example, the design should reduce the corrosion hazard of the structure, avoid the accumulation of water and sediment, ensure that the coating can be evenly covered and easy to construct and inspect. In addition, electrochemical corrosion protection measures when connecting different metals, as well as anti-corrosion protection during loading and unloading, transportation and installation are also discussed. This standard provides comprehensive guidance for the anti-corrosion design of steel structures and is suitable for the selection and construction of protective coatings systems.
