Hot Dip Galvanizing Distortion
If steel fabrications distort throughout galvanizing, it is all because of ‘built-in’ stresses being discharged. At that time, the steel is heated to the galvanizing temperature. Steel tends to suffer from stresses on its own, but stresses can also be introduced by cold forming, welding, and hole punching. What is galvanization and its associated risks? When it is decided to hot-dip galvanize, it is the responsibility of a design engineer to ensure that all the pieces can be appropriately fabricated for the best quality galvanizing. An engineer should adopt the best practices, which recommend that the steel to be galvanized should have similar thickness and symmetry. During the process of hot-dip galvanization, steel progresses via a temperature cycle while immersing and withdrawing from the bath. It is due to the fact that parts are dipped at an angle, it gives rise to uneven heating and a temperature profile along that part, which is being galvanized. These stresses ...
