The material of the steel structure engineering is mainly steel. It is well known that the steel structure has many advantages
But there are also many shortcomings, that is, it is easy to corrode. Under various atmospheric environment conditions
The use of corrosion is easy to produce, which is a natural phenomenon. How does steel structure plant effectively rot?
Professional answer for you: The main performance of steel in steel structure engineering needs to be analyzed from mechanical performance and chemical composition,
1. Steel The mechanical properties
The yield strength, tensile strength, elongation of stretching, cold bending performance and impact toughness under the index are also called mechanical performance.
2. The chemical composition of steel
Carbon structure steel consists of pure iron, carbon and multiple impurities elements, of which pure iron is about 99%. Low alloy structure steel is also added with alloy elements, but the total amount usually does not exceed 5%. The chemical composition of steel has an important impact on its performance.
Third, color steel tile paint surface, pH in the air, transportation, installation, paint surface will also be damaged. The humidity acid and alkali gangsters have been aging rust in 3-5 years. If it is not maintained for 5-6 years, it will be scrapped. How does the steel structure plant effectively resist acid and alkali and isolate air? anti-UV? Protecting the original paint is not aging? The surface corrosion of color steel tile steel is divided into four grades of A, B, C, and D. The surface corrosion level of color steel tile steel is D -Class D and C, that is, A, B, C, and grade. (D has been rusty) No anti -corrosion is recommended. Because the construction requirements for color steel tile anticorrosive materials are very high, in
https: www.sgsbuilding.comnewsindustryCrude-Steel-PRODUCTION-in-February-2022 It can achieve the best results before rust. At the same time, the cost is not very high, which can be effectively extended for 8-10 years in the original color steel tile life.
