Galvanized steel is carbon steel that is hot dipped and coated with zinc on both sides of the steel itself. Through hot dipping, the iron-zinc alloy forms a bond to prevent the carbon steel from rusting.
Before hot dipping can occur, the surface prep to the steel is critical to ensure the zinc adheres properly and provides the necessary protection to the steel.
The governing specifications of hot dip galvanizing are:
- ASTM A123/A123M
- ASTM A153/153M
- ASTM A767
- CSA G164
- ISO 1461:2009
