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 coated 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
