Hot-dip Galvanization: Best Solution Against Rusting and Corrosion
Hot-dip galvanization has been extensively used to prevent corrosion for 100 years. Hot-dip galvanized steel has a great lifespan. This effective form of galvanization provides 2 levels of protection : – Barrier protection – Cathodic protection In Cathodic protection, Zinc protects the underlying material. If any part is scratched, Zinc will prolong its protection. Zinc can also function as a barrier slowing down the corrosion rate. What is Hot Dip Galvanizing? Hot dip galvanizing is a process developed to prevent steel from corroding. Before the process can take place, the steel goes through a thorough chemical clean which removes all rust, oil and mill scale from the surface. When the cleaning solution has been rinsed off, the coating process can begin. The steel is dipped into a bath of molten zinc heated to around 450°C (860°F) before being left to cool in a quench tank. When the cooling process is complete, the zinc coating is then metallurgically bonded to the steel. The
