Galvanizing Process

What is Galvanizing Process?

Galvanizing is the process of immersing steel pipes in a bath of molten zinc to produce a corrosion resistant, multi-layered coating of zinc-iron alloy and zinc metal. While the steel pipe is immersed in the zinc, a metallurgical reaction occurs between the steel and the molten zinc. This reaction is a diffusion process, so the coating forms perpendicular to all surfaces creating a uniform thickness.

The three main steps in the hot-dip galvanizing process are surface preparation, galvanizing, and post-treatment. The process is inherently simple, which is a distinct advantage over other corrosion protection methods.
