What is steel beam corrosion?

Steel is a desirable material for making iron beams due to its suitable properties such as lightness, high strength and durability, and compatibility with the environment. However, steel beams are subject to corrosion. The main cause of iron beam corrosion is its exposure to water and oxygen. Also, the effect of corrosive environments and salt water on the rusting of iron beams should not be neglected. Since the beam is one of the main components in the building, its rusting can become a problem. Therefore, to prevent and fix the rusting of the beam, it is necessary to take preventive measures before using it in the structure. What are the main reasons for rusting of iron beams?

As one of the main and key components of steel structures, iron beams play an important role in the strength and stability of structures. But rust is one of the main problems of beams that can lead to weakening of the structure and reducing its useful life. It is very important to know the main reasons for the rusting of iron beams for its prevention and control. The main reasons for rusting of beams are: Moisture and water: The presence of moisture and water is the most important cause of iron beam rusting. Water accelerates the oxidation reaction. Oxygen: The contact of the iron beam with oxygen in the air leads to iron rust. Salt and chemicals: Salts and chemicals in seawater, acids and bases cause corrosion. Mechanical stresses: stresses caused by loading, impact, etc. make the surface of the beam prone to corrosion. Lack of proper coating: Failure to use protective coatings such as paint and galvanization causes rust. By knowing these factors, it is possible to prevent the rusting of beams by using appropriate methods.
