: Chad,
: as you know anything that is 'galv' has zink as a primary
: material. Zink is hard to stick paint to.

Randy and Chad,

The galv does mean zinc coated, but in this case the zinc coated sheets are heat treated at up to 700 degrees C to form an iron/zinc alloy "shell" on the product. This give excellent corrosion resistance (zinc) while remaining workable and paintable (iron). Galvanneal is the most used steel in the US automotive industry right now and is the reason that the big 3 can now offer lifetime rust-through warranties.

Many roofing companies are now starting to use it also.
