Galvanized vs. galvannealed
Galvanized vs. galvannealed
(OP)
Is there any difference in corrosion protection for steel sheet hot-dip galvanized (zinc coated) vs. the heat-treated or "galvannealed" material that produces a zinc/Fe alloy at the surface? The environment is indoor and possibly outdoor on commercial buildings.
