The corrosion of structural steel is an electrochemical process that requires the simultaneous presence of moisture and oxygen. Essentially the iron is oxidized to produce rust. The rate at which this corrosion occurs varies greatly depending on external factors such as humidity and degree of pollution. Hence the corrosion preventive measures that need to be taken for structures present in cool and dry climate is relatively lesser as compared to the steps taken for structures in aggressive climates. These structures also need to be designed with maintenance in mind if extended life is required. The design and detailing of a structure also greatly influences the durability of any protective coating applied to it. For example, structures designed with small structural components and fasteners are tougher to protect than those with large flat surfaces. With years of experience to support us, BUILDTECH® INDIA specializes in both types of structures and constantly evolves the process to suit the project at hand.
While designing a suitable corrosion protective system the key issues to keep in mind include:
- Access to coating application and maintenance
- Avoidance of Moisture and debris traps
- Avoidance or sealing of crevices
- Drainage and ventilation to minimize the time of wetness
Surface preparation is perhaps one of the most essential first stage treatment before the application of any coating and is generally accepted as a deciding factor in the degree of success any corrosion control process would have. Surface cleaning not only prepares the steel surface but also makes it suitable for adhesion. Further, the performance of the coating is influenced by its ability to adhere to the surface material. BUILDTECH® INDIA ensures the success of the corrosion control measures it carries out by carefully monitoring the quality of materials used and each step of the process. Standard methods used to apply paints to structural steelwork include application by brush roller, conventional air spray, and electrostatic airless spray, depending on the project at hand BUILDTECH® INDIA used the best-suited method for an efficient and effective corrosion control method.
