Galvalume vs. G90

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.		Rob Noah 3/22/2016	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/21061/find/
Rob, does this paper help? http://www.metalconstruction.org/index.php/media-center/press-releases/metal-roofs-can-last-60-years I will check for tests that compare Galvalume to Galvanized		Dick Bus 3/22/2016	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/21062/find/
Dick, Thank you for the quick reply. I have read through this paper from the Metal Construction Association (MCA) and Zink Aluminum Coaters (ZAC) Association and couldn't find the above statement. If yo find anything else, feel free to email me directly. Thank you for your help. Rob		Guest User 3/24/2016	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/21063/find/
