Why build with steel? Corrosion Resistance
Galvalume Plus, by virtue of its combined protection of aluminum and zinc, has at least twice the service life, in most atmospheric environments, of conventional galvanized steel with the same coating thickness.
In a series of exposure tests performed over a 13-year period by Bethlehem Steel, Galvalume Plus steel was found to outlast galvanized by:
- Four times in exposure tests in a severe marine environment
- Twice as long in a less severe marine location
- Six times longer in industrial environments
- Three times longer in rural situations
