  Steel Structure Surface Related Design Anti-corrosion Coating 1. The adhesion between the anti-corrosion coating and steel base should not be lower than 5MPa. 2. For newly designed steel structures , it is not suitable to use rust coating for descaling and painting, and when rust coating is required for repairing the steel structures of existing buildings, it should be used after the demonstration. 3. The fireproof coating on the surface of the steel structure generally does not have an anticorrosive effect, so the fireproof coating should not be used as an anticorrosive coating. The surface of the steel structure should be coated with antirust primer, corrosion-resistant intermediate coating, fireproof coating, and then anticorrosive surface coating according to the structure of protection treatment. 4. Galvanized steel plating amount of micro-corrosive, weak corrosion or corrosive environment in the double-sided galvanized amount should not be less than 180g/m2, 250g/m2, or 280...

  Design related to different structural elements Anti-corrosion Coating 1. The friction surface of high-strength bolt connection should be processed strictly according to the design requirements, and ensure that the anti-slip coefficient meets the requirements of the bearing capacity, without special requirements, its rust removal level should be the same as the rust removal level of the main material. 2. When the connection is in the open air or in a moderately corrosive environment, the friction surface after descaling should be coated with inorganic zinc-rich primer or zinc plus primer coating level structure, and the thickness of the coating should not be less than 70μ. 3. Common bolts in moderately corrosive environments shall be galvanized bolts. 4. The buried part of the steel column foot should be wrapped with dense concrete of strength class not less than C20 (the thickness of the protective layer should not be less than 50mm), and not less than 50mm above the indoor grou...
