Batch hot-dip galvanizing has been the most commonly used method of protecting steel products from corrosion. The reasons are simple – the hot-dip galvanizing (HDG) process has been around for over 200 years, it is well known and understood, it can be well controlled, and it is relatively cheap. What is most important for many industries, however,is excellent corrosion protection that HDG coatings provide for steel structures exposed to harsh environments. Bridge, highway, electrical utility, industrial and marine construction projects have all realized the benefits of hot-dip galvanizing.
