How are steel structures anticorrosive?

　　The characteristics of steel structure and the increase of national steel production are the rapid development of steel structure. Steel structure has many advantages. It is easy to corrode. The newly built steel structures usually need to remove rust, galvanized or brush paint carefully, then repair it again after a certain time. So how do steel buildings anticorrosion? The steel structure of Foshan tells you that the main properties of steel in steel construction should be analyzed from mechanical properties and chemical components.
1. mechanical properties of steel: it refers to the yield strength, tensile strength, elongation and impact toughness of steel under the standard conditions, also known as mechanical properties.
2. the chemical composition of steel: carbon structural steel consists of pure iron, carbon and a variety of impurity elements, of which pure iron accounts for about 99%. In low alloy structural steels, alloying elements are added, but the total amount is usually not more than 5%. The chemical composition of steel has an important influence on its properties.
Foshan steel structure company said that in order to reduce or prevent the corrosion of steel structure, the coating method is basically applied at home and abroad, that is, the protective layer is used to prevent metal corrosion.
