Durability Calculator

Hot-dip galvanized steel resists corrosion in numerous environments and can last as long as 170 years under certain conditions. The corrosion rate of the zinc is directly related to the function of the coating thickness and the amount of corrosive elements in the environment.


Three, intermetallic layers are formed that are harder than the fabricated steel for excellent resistance against abrasion.


Constant exposure to temperatures below 200C is an acceptable environment for hot-dip galvanized steel. If exposed to temperatures above 200C, good performance can be achieved if exposed on a periodic basis.
