GalvInfo Notes

The cornerstone of this section, and a good starting point, is a series of information bulletins referred to as 'GalvInfoNotes.' The GalvInfoNotes serve as an excellent primer on the terminology and use of zinc-or metallic-coated steel sheet, similar to a 'frequently-asked-questions' section - but with more detail. The GalvInfoNotes will open in a new browser window as Adobe Acrobat documents.
