The reason why anti-corrosion paint for steel structure is widely used

In recent years, more and more attention has been paid to the anti-corrosion of steel structures. We all know that steel structures or steel will suffer double corrosion as long as they are affected by humid atmosphere or polluted environment, and eventually pulverize and end their service life. Therefore, in the coating process of steel structures, the primary consideration is its construction conditions to ensure the specification of the construction environment. Steel structures are used more and more in building structures, and many large convention and exhibition centers, stadiums, airport terminals, TV towers, etc. use steel structures as the main structural form. To ensure the integrity of the steel structure building and show the artistic appeal of the steel structure, it is an economical and feasible method to use heavy-duty anti-corrosion paint for coating protection, which can achieve a service life of more than 15a. If the metal thermal spraying and heavy-duty anti-corrosion coating are used for double protection, the service life of more than 25a can be achieved. Steel is an important structural material in modern buildings, with high strength, stable performance, good toughness, convenient processing and production, suitable for mass production, easy quality control, and quick installation. In the coating design of steel structure buildings, not only the long-term service life of heavy-duty anti-corrosion coatings, but also environmental protection should be considered. Heavy-duty anti-corrosion coatings for steel structures should reflect the best combination of performance, aesthetics and environmental protection. There are various matching schemes for steel structure paints, which can be determined according to the use environment and service life. Now the fluorocarbon paint with the best anti-corrosion performance on the market can be matched with epoxy zinc-rich primer + epoxy micaceous iron intermediate paint. It can be used for 15-20 years in atmospheric environment.
