 How does galvanizing protect steel from corrosion?
Zinc metal used in the galvanizing process provides an impervious barrier between the steel substrate and corrosive elements in the atmosphere. It does not allow moisture and corrosive chlorides and sulfides to attack the steel. Zinc is more importantly anodic to steel - meaning it will corrode before the steel, until the zinc is entirely consumed. |
