Corrosion Rates of Galvanized Steel from Galvanizers Association

The atmospheric corrosion rate of hot dip galvanized articles is predictable and offers considerable benefits to the specifier over uncoated steels.

In many cases, it is essential to provide corrosion protection for the steel in order to meet the design life of a structure and in most cases hot dip galvanizing provides an economical and attractive solution.

A designer must take into account the location of the finished article, which requires a consideration of the regional or macro environment, the site and local or micro environments around the location as well as an understanding as to whether the environment will change over time.

Hot dip galvanized articles have performed successfully in the Australian environment for many years and their durability is well understood.

Numerous structures have performed for over 50 years, with documented cases of products lasting over 100 years.
