The ISO 1 2944.4 - 2017 standard deals with the protection of Paints and varnish for steel structures, with a specific focus on surface types and their treatment methods. This section defines treatment standards for various steel surfaces, including non-coating, thermal spray zinc, aluminum alloys, hot dip galvanizing, etc., and details surface cleanliness, surface profile, surface preparation grade, and temporary protection methods. The updated standard removes unused terms, adjusts the appendix structure, and adds new treatment content. It aims to provide clear, detailed guidance on anti-corrosion coatings for steel structures to ensure long-term effective protection.
