Paul L [name deleted for privacy] ITW Magnaflux - Manchester, Iowa, USA   GALVANNEAL Carbon steel sheet with a fully alloyed iron-zinc coating on both sides. I don't know if you would consider it simple, but it may have a different galvanic potential compared to some electrode. Tom Pullizzi Platronica.com Falls Township, PA   Galvanizing, where 100% Zn on the top surface of the steel,where as in Galvannealed,90-93% Zn with 10-7% Fe on the top surface. The simple way to distinguish is that Galvannealed material will look like matte finish, where as Galvanized material will look like bright finish.
