What is hot-dip galvanizing and why is it the best way to protect steel?
What is hot-dip galvanizing?

Hot-dip galvanizing is a process in which steel parts are immersed in a bath of molten zinc after surface preparation. In this process, a uniform and resistant layer of zinc reacts with the steel surface and creates a permanent coating that protects the steel from rust.

Why hot-dip galvanizing is superior to other coatings

In addition to creating a physical protective layer, hot-dip galvanizing also has cathodic protection properties; meaning that even if the surface is damaged, the zinc layer protects the steel. This feature makes hot-dip galvanizing perform better than paint and temporary coatings.

Hot-dip galvanizing applications

This method is widely used in coating lighting poles, lattice and circular electric poles, road guardrails, metal structures, pipes and profiles, and industrial equipment.

Frequently Asked Questions

How long does hot-dip galvanizing last?
