Galvalume vs. G90 | Ask The Experts Forum

Rob Noah 3/22/2016	I have read on several manufactures' websites and marketing literature that "tests show that Galvalume is 3 to 4 times more corrosive resistant than G90 in most applications" but they never back it up with a reference for the tests. Can you provide a link to where I can validate this statement with actual documentation? Thank you.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/21061/find/
