New galvanized what ? -Are you talking about galv steel framing ? If so it need no priming. Steel studs are within the wall and do not need any kind of primer or paint.
Paint? No. Primer? YES. Corrugated steel is galvanized so you will need an etching galvanized metal primer. Regular paint or primer will peel off in no time! The etching primer as you can guess by the name actually reacts with the steel for a better bond. The steel should be sandblasted beforehand, or al least pressure washed thoroughly. The paint will adhere to the primer. Go to any real paint store (not a big box store with a paint department), let them know what you want to do and they will be glad to help and answer any questions.
