What is the difference between the Galvalume Metal you use for metal roofs and the competitors Galvanized Metal?
Galvalume sheet has been successfully used in roofing applications for more than 25 years; it has been evaluated in outdoor tests for well over 30 years. Based on these tests, in which corrosion weight losses were measured and compared with galvanized, Galvalume sheet is projected to outlast galvanized sheet (with and equivalent coating thickness) in various atmospheres by up to (9) nine times.
