❯ Hot Dip Galvanizing – Corrosion and corrosion protection (Part II)

Dr. Caius Bulea

Abstract: The article concerns to the hot dip galvanizing process that realize the coating of a thin layer of zinc on the steel product surface by immersion in molten zinc. They contend that the objective of hot zinc coating is to protect the steel products against corrosion. Below is the cost analysis. The cost of zinc coating is compared with the costs of painting and these costs are distributed over the entire life of a building. The conclusion is obvious: hot dip galvanizing it is the best corrosion protection process known today for steel structures and also the most inexpensive method of corrosion protection currently known. Hot dip galvanizing resists corrosion for at least two times longer than paint and cost twice less.
